Very good thought process of what time really is to humans. Maybe the Egyptians had it right all along and knew way more than what we now know.

JADES, my vote is definitely for the deep field of JWST. The find of orgo that soon, wow!!! I wonder how many super Nova would have to happen to get enough elements for large amount of orgo molecules,?
Fraser, do you know if the falcon 9 has any moving parts to transfer the center of mass from one tip to the other? i really can't grasp my mind around a huge steal hollow rod going up and down at tens the speed of sound and then landing like a hummingbird on a flower
At 14:45, isn't it literally possible and no longer theoretically possible, since they succeeded with a demonatrator project? Not sure how practical it is, but it sounds like it's no longer just theory, then again i think we have demonstrated terrestrial power transmission this way before.
It's probable that the main reason that Betelgeuse is behaving so weirdly is because of the mass ejection that caused it to dim in the first place. When that amount of material is ejected from a star there are going to be aftereffects, in this case large amounts of plasma sloshing around in the same way a bath sloshes around if you quickly pull a large bucket of water from it. In this case the effects on Betelgeuse would include shockwaves causing the core of the star to ring, and collisions between large amounts of plasma at very high speeds, the effects of which would lead to increased fusion and a brightening of the star.
I wonder if these brightness fluctuations could be attributable to the end of an elementary burning cycle, be it Carbon, Oxygen or any other heavier element(s).
I assume that the 500 light year distance of Betelgeuse is enough to protect Earth life from significant effects when it goes supernova. Maybe you covered this issue in a previous video. Great explanations. I also hope that Starliner flies successfully before too long.
I sure hope Betelgeuse will go nova in my lifetime. That would be even better than watching Halley's comet. It will need to hurry though. lol. So Betelgeuse is my favorite story this time. As for power from space. One of the big advantages when the technology is developed enough would be that the power receivers on earth would receive power long before sunrise and long after sunset. That would drastically reduce the time that energy needs to be stored or generated in another way. (if I remember correctly, there are even some satellite constellations that could generate power close to 24/7)
In Bladerunner, when Roy Batty gives his iconic speech at the end, he says in part; "If you could see what Ive seen with these eyes. Attack ships on fire, off the shoulder of Orion." It was many years later that I realized that the shoulder of Orion is actually Betelgeuse (Alpha Orionis). Just putting that out there. Kinda wonder if those attack ship were on fire because of war, or Betelgeuse was throwing a fit and hitting them with unexpected solar flares about a thousand times more lethal than our sun. Becuase if you think about it, there couldnt be an offworld colony there. Betelgeuse is far too volatile.
I often stand in our darkened garden, in the Southern Hemisphere, gazing at Betelgeuse and quietly pleading "Go on, just do it! Just explode before I shake off this mortal coil." It never does. Eventually my wife calls me to come back indoors. She threaten's to speak to our doctor!
Hi, very random question: How would one measure mass in microgravity - lets say on board the ISS? I.e. I would imagine it comes up in various experiments, and apart from a centrifuge and measuring the pull i couldn't really come up with a decent way. And the centrifuge way might not be the best choice for all scenarios, for example if we want to measure how much biomass we produced in some plant growth experiment, where the object can be somewhat large (plus the plant might not take it kindly).
@Frasier Cain Would it make sense to launch a Solar Gravity Lens mission to catch Betelgeuse in the act? Or maybe send probes in it's direction for direct sampling and/or monitor the effects on the Heliosphere?
There are several stars withing 10 Light years of the sun so no doubt there are atars withing 10 light years of beatelgeuse and beyond and no doubt some of these stars have planets.
Space based power was a thing in the old Maxis/EA Sim City games. Microwave power, only caveat was that there was a disaster available where the satellite could get misaligned with the ground station and you have some nice crispy microwaved citizen sims. The video of the Falcon 9 landing was a software stabilized video, if you noticed how the top of the frame moves down near the end.
So question, asuming that, that paper on betelgeuse is correct and it has "10s of years" left; wouldn't that mean that its already blown up and we're just waiting on the light of the explosion to reach us...
How are they transmitting the power to and from space? Wouldn't it be dangerous with more power, in case of some issues with the satellite or if something get in between?
Awesome story. Love your RUclips channel and what you do!! I learn so much!!! Boeing will get it figured out. Better to find out now than something happens on flight 😮. Great job as always
What would be the best way to beam energy? Signal going through storms, rain, wind, snow. But it seems a network of geostationary satellites with highly-efficient transmission of energy whether laser, microwave, radio...should give a nice boost to global grids.
*Solution to the "Time Light Problem"* The reason why people often stumble over the *assumption* that light years in outer space equals the same measure of distance and passage of time on earth is because general relativity is not being taken into account. In general relativity, the local rate of time and the measure of distance depend on the amount of matter or mass in the vicinity. Locally, the rate of time and measure of distance doesn't change much inside of our galaxy. However, the distance in our line of sight between us and distant galaxies is extreme and running at a much faster rate of time as well as an expanded measure of distance outside our galaxy compared to where we are near Sagittarius A's Milky Way black hole (where our rate of time is much slower and our measure of distance is much more contracted). The same way the earth appears flat locally, our universe also appears to be flat locally. However, over great distances throughout the universe there are differing measures of distance and differing rates of time from black holes to the lagrange points between black holes where there is very little acceleration compared to our relatively flat contracted local frames of reference near Sagittarius A. When we observe other galaxies, we are effectively looking at vastly differing measures of time and distance relative to our local observations within the gravitational force of the mass of the Milky Way galaxy. This can lead to various observed phenomena as we look into outer space such as redshift, superluminal motion and the apparent faster motion of the outer spiral arms of galaxies. It's not the same as our flat observations of cats and dogs locally here on earth where we don't observe differing measures of distance and time. So the supposed expansion of the universe, imaginary inflatons, invisible dark matter and dark energy or vacuum energy are *not* required to explain the observed redshift of light from distant galaxies or the faster than expected motion of the outer spiral arms of galaxies. As predicted by general relativity, the expanded space between galaxies due to the absence of matter in our line of sight where much less acceleration can explain the observed redshift without the need for a nonsensical universe expanding into oblivion for no apparent reason and it explains the faster than expected motion of structures and objects the farther it is from supermassive black holes. It turns out that the vacuum energy of space is due to the frame dragging of black holes that are growing from gobbling up spacetime regardless of the amount of matter being consumed. Recent findings of a team of scientists have found that dark energy or vacuum energy is associated with supermassive black holes that are all growing in size, as opposed to an ever expanding universe. It turns out that light is blue shifted going into a gravitational well so the converse is true of being redshifted traveling great distances outside of gravitational wells. Supermassive black holes are the most powerful forces in the universe with far reaching effects of gravity and vacuum energy. The problem and solution is that between galaxies, all of the galaxies all around are all together pulling and drawing in spacetime as well as exerting equal gravitational forces on empty space. This is the reason there is very little acceleration between galaxies and where there is expanded distance and a faster rate of time. The clocks are running faster outside of galaxies and the measuring sticks are larger meaning things are actually less distant than they appear. The more gravity drops off outside of the galaxy and in between galaxies, the more distance will be expanded and the faster the rate of time will be. As predicted by general relativity, the expanded space between galaxies due to the absence of matter in our line of sight where there is less acceleration explains the observed redshift without the need for a nonsensical universe expanding into oblivion for no apparent reason at all. The differing rates of time and differing measures of distance also explain *how* a day is the same as a thousand years and a thousand years is the same as a day, at the same time in the same universe. 13.8 billion years is the same as 6,000 years and 6,000 years is the same as 13.8 billion years *within the same created universe!*
Being 73 I would not expect to be around to witness the supernova phenomenon of Betelgeuse...but what an absolute life experience that would be...terrifying but at the same time, the most fantastical, beautiful show the cosmos could ever provide us...🌃
About the perfect locked in view of Falcon 9 landing: several artifacts show that it's been digitally stabilized. First when the engine lights up, the rocket wobbles a bit. That means the view moved a bit and the shutter scan had an effect on the apparent size of the rocket. So it wobbled. Second, you can see the framing in top of the image when the rocket lands. That means the camera tracked too low. It was good, but it was not a perfect tracking.
Did anyone notice what looked like lightning on the Mars live stream at 17:38? About four frames have a moving flash but it would be really big, so it must be a glitch.
NASA contracting with private companies completely killed the vibe. It’s like awesome space exploration, except now we’re making a few rich a-holes way more rich… for some reason… 😒
Oh interesting, sure, if there were clouds high in the atmosphere, you'd see a supernova-bow. Whoa, but I wonder if you'd see different colours because it would be a different source of illumination. That's actually a mind-boggling question...
@@arnelilleseter4755 time scale for C, Ne, O, Si are 1000 y, 3 y, 4m, 5d for a slightly more massive star. Core collapse is seconds . We should see it coming.
Rain bows we see on earth are not created in space, sunlight going through water vapor or rain causes them here, I would think that it's possible in space but temperatures for water in space is not conducive
have to remember too.. we arent seeing the star as it is now.. but as it was... ( however long ago determined from speed of light) whatever many years ago
❓ What are some of the best practices or tips that you would give to aspiring space & astronomy journalists❓How do you differentiate yourself from other space and astronomy journalists in terms of your style, approach, or perspective?
I'd also like to add that the JWST images of these earliest galaxies are beginning to show up on Galaxy Zoo for classification. If you're someone who likes astronomy and has some spare time, you might want to take a look. (For those who don't know what I'm talking about, Galaxy Zoo relies on citizen scientists to classify galaxies and point out anything of note. Occasionally you'll see something really spectacular.)
9:45 Just spitting ideas. But it would be cool to know if, Jupiter being Jupiter had a collision with another smaller planet or other with a core. But it had a different density which is why there seems to be separation and influence on the surface scans.
When Betelgeuse does go supernova, will it appear as brightening over weeks and months, or will it just be like a giant lightbulb turned on in the sky?
Space based power might find a niche in solving the long haul electric aircraft problem. Battery technology might advance sufficiently to negate even that, but it's a use case where I can't think of an alternative power source that doesn't involve hybrid propulsion.
If the first stars in the early universe had much shorter lifespans and all formed about the same time, shouldn't there be a sweet spot in time where super novae happened with relatively common frequency? Is that something observed? Expected?
14:45 I think it demonstrated it to be possible in practice, not just in theory, considering they did it. ;) 18:20 It's been stabilized in post, far less impressive of a feat than perfect tracking with a camera. Still a pretty cool video though, even if my vfx-artist side is bothered by the shoddiness of the execution and the absolutely zero effort made to avoid the stabilization artifacts. :)
Re: Jupiter's blue spot... Is it possible that Jupiter has what could be described as a compound core where there are 2 or more large masses of heavy material rolling around each other? I would imagine such a configuration could exist if high mass or high density objects conjoined during the early formation of the planet without collapsing into each other.
Space based solar power good for polar orbit satellites, down to temporary science or military outposts where the extra infrastructure would be hard to bring. In the summer get power above the Arctic, 45 minutes later you're beaming it to Antarctica.
As everything is cyclical the old universe collapsed and boom, the big bang happened but this may have happened in multiple places and different times across the universe. It would be silly to think there was only one big bang. It would be like thinking there was only one galaxy or one star system. This concept would allow for differences in our thoughts on distance and time.
Hi Fraser, Firstly thank you for all your hardwork! Your podcast makes long distance driving much more enjoyable with something interesting to listen too! I’ve been wondering for a while, have we been thinking about terraforming all wrong. Shouldn’t we be focusing on “bio-forming” . So instead of trying to make a planet like earth, we make a dynamic ecosystem which is setup for organisms on that specific world. Such as creating a biosphere on Mars which creates its own magnetosphere via bio-magnetism. Is this all gobbledygook or actually feasible? Thanks, Ophir
I can't think of how an organism could generate a magnetic field that's equivalent to a 1000 km ball of spinning metal. But it could help produce an atmosphere that would help block the radiation.
Hi Fraser love your content as always. Everywhere we look in space we detect CMB. Any chance that is what is pushing the expansion of the universe?? Inside of dark energy as we think?
What NASA could do regarding Starliner's electrical cabling and its flammable insulation is to paint all the cables with West System epoxy, the hardest and toughest epoxy in the universe (used for boats and canoes), and absolutely non-flammable. Far cheaper than having to redo the wiring, and far easier than to wrap anything around the cables; and probably far safer, as a wrapping would leave gaps, while a couple of coats of epoxy will probably not leave even a single point of exposed flammable material.
@@frasercain This WS epoxy is pretty light, in spite of its amazing strength. I know because when I've used it I often had a glassful of mixed liquid left-over, which solidified in the plastic cup or whatever I mixed it in, and then it hardened and I kept it as a souvenir, and it is definitely lighter than water. And thinking about this in comparative terms, the solution that NASA considered, of over-wrapping all the cables, THAT would definitely add more weight than a coat or two of this epoxy varnish. To get to a millimeter thickness, as used to bullet-proof those kayaks for navigating rocky rapids, for example, it takes about 10 coats of the stuff. This solution would be superior, in that a manual over-wrap would leave gaps, whereas painting with epoxy, specially a double-coat, would not leave even a point anywhere of exposed flammable material. Additionally, WS epoxy is the toughest in the world, famous for it, and so doing this would strengthen all the cabling against accelerations, vibration and whatnot. I left a message for NASA through their website Contact; I hope they read it and consider it. EDIT: Been looking for density info on West System epoxy, but can't find density data. However, suffice it to say that this epoxy does not "want" to be applied thickly; it "slowly runs", pardon the oxymoronic sound... This is counterintuitive because it is quite viscous, which one might incorrectly assume to imply something about surface tension ... West System epoxy has almost zero surface tension; it flows slowly but it flows steadily. If you paint it on top of a wooden surface with a thin crack, it will slowly but steadily penetrate the crack and start dripping from the underside. Painting cables with it, and trying to be "generous" with it, would probably result in the stuff dribbling down the cable to the lowest point and dripping from there; so it kind of forces you to apply it thinly for it to NOT do that.

Is there a reason why JWST bypassed UV which would also make it 20X bigger?
I know you've been in there for a while now, but I like your new studio. The lighting is good and the image and sound are really on point.
Thanks, it's a process. Definitely so much easier to create content now.
When Betelgeuse explodes everybody on the planet will experience what the summer is like at night in Alaska. Lol
It won't be that bright. Not a second Sun, more like a crappy moon.
@@frasercain I was wondering about that. Still would be pretty incredible to see!
Plants are NOT doing it around my house right now, because it is dark.
That's amazing, because the rain in Spain falls mainly on the plain. Couldn't resist.
I hope Betelgeuse 'splodes in our lifetimes 🤞👀🤞 What a magnificent site that would be, and what an honor it would be to witness it!
Yep, it would really be amazing if it actually happens on our watch.
Oh Fraser... I get it... Rockets that land like in Buck Rogers ! It's still gives me goosebumps !
JADES, my vote is definitely for the deep field of JWST. The find of orgo that soon, wow!!! I wonder how many super Nova would have to happen to get enough elements for large amount of orgo molecules,?
I like the starliner story.
They really need to double check their MCAS systems, to the MAX
Super excited about the NIAC interviews, great work!
Thank you for the excellent coverage of space news!
Great episode. So much great information 😘
Maybe if all of humanity says "Betelgeuse, Betelgeuse, Betelgeuse" at the same time, it'll explode. :D
Thanks for all the news, Fraser! 😊
Stay safe there with your family! 🖖😊
Thanks as always!
That falcon 9 booster video is as brilliant and it is beautiful.
Fraser, do you know if the falcon 9 has any moving parts to transfer the center of mass from one tip to the other? i really can't grasp my mind around a huge steal hollow rod going up and down at tens the speed of sound and then landing like a hummingbird on a flower
At 14:45, isn't it literally possible and no longer theoretically possible, since they succeeded with a demonatrator project?
Not sure how practical it is, but it sounds like it's no longer just theory, then again i think we have demonstrated terrestrial power transmission this way before.
I hope we get to see it!
I really hope it goes supernova in my lifetime (and yours too Fraser!!!) Edit: Also hoping to see pop 3 stars via JWST.
Same. I'm so ready.
I have it on ny list. right under a dual lap dance from Joey Heatherton and Ann-Margaret.
I would love to see this too!
As always you deliver good info
The rain in Spain is mainly in (terfering with pictures of) the plains (of Mars being seen).
Thanks for letting me know I’m not the only one who remembers
15:24 I am unable to find the "Space Power Grid" interview...?
Here it is

Seeing these molecules are in line with doubting our ideas of deep time atleast in the concept of entropy time form.
Thanks for the news man!
It's probable that the main reason that Betelgeuse is behaving so weirdly is because of the mass ejection that caused it to dim in the first place. When that amount of material is ejected from a star there are going to be aftereffects, in this case large amounts of plasma sloshing around in the same way a bath sloshes around if you quickly pull a large bucket of water from it. In this case the effects on Betelgeuse would include shockwaves causing the core of the star to ring, and collisions between large amounts of plasma at very high speeds, the effects of which would lead to increased fusion and a brightening of the star.
I wonder if these brightness fluctuations could be attributable to the end of an elementary burning cycle, be it Carbon, Oxygen or any other heavier element(s).
I assume that the 500 light year distance of Betelgeuse is enough to protect Earth life from significant effects when it goes supernova. Maybe you covered this issue in a previous video. Great explanations. I also hope that Starliner flies successfully before too long.
Yeah, supernovae are only a problem if they're within 30 light-years or so.
Yes, what a time to be alive!!
I sure hope Betelgeuse will go nova in my lifetime. That would be even better than watching Halley's comet. It will need to hurry though. lol. So Betelgeuse is my favorite story this time.
As for power from space. One of the big advantages when the technology is developed enough would be that the power receivers on earth would receive power long before sunrise and long after sunset. That would drastically reduce the time that energy needs to be stored or generated in another way. (if I remember correctly, there are even some satellite constellations that could generate power close to 24/7)
This is exactly why I think wind farms are a better idea than solar panel arrays.
this is exciting ! thank you
In Bladerunner, when Roy Batty gives his iconic speech at the end, he says in part; "If you could see what Ive seen with these eyes. Attack ships on fire, off the shoulder of Orion." It was many years later that I realized that the shoulder of Orion is actually Betelgeuse (Alpha Orionis). Just putting that out there. Kinda wonder if those attack ship were on fire because of war, or Betelgeuse was throwing a fit and hitting them with unexpected solar flares about a thousand times more lethal than our sun. Becuase if you think about it, there couldnt be an offworld colony there. Betelgeuse is far too volatile.
I often stand in our darkened garden, in the Southern Hemisphere, gazing at Betelgeuse and quietly pleading "Go on, just do it! Just explode before I shake off this mortal coil." It never does. Eventually my wife calls me to come back indoors. She threaten's to speak to our doctor!
Hi, very random question: How would one measure mass in microgravity - lets say on board the ISS? I.e. I would imagine it comes up in various experiments, and apart from a centrifuge and measuring the pull i couldn't really come up with a decent way. And the centrifuge way might not be the best choice for all scenarios, for example if we want to measure how much biomass we produced in some plant growth experiment, where the object can be somewhat large (plus the plant might not take it kindly).
@Frasier Cain Would it make sense to launch a Solar Gravity Lens mission to catch Betelgeuse in the act? Or maybe send probes in it's direction for direct sampling and/or monitor the effects on the Heliosphere?
You could never reach it from here. I think it would be a great target for an SGL mission, though.
I’m 75. I hope Betelgeuse goes nova sooner.
To see it go supernova, we all need to say "Betelgeuse, Betelgeuse, Betelgeuse!" at the same moment. Maybe if we chew betel nuts and chant Betelgeuse?
It could happen.
Question: Do we know of any worlds sufficiently close to Betelgeuse that the supernovae would be more than just a light show?
Google said no.
There are several stars withing 10 Light years of the sun so no doubt there are atars withing 10 light years of beatelgeuse and beyond and no doubt some of these stars have planets.

Oh noooo the NIAC interviews finished? I found those really interesting. Oh well, here is hoping for next round not being tooo far away 🤞
Space based power was a thing in the old Maxis/EA Sim City games. Microwave power, only caveat was that there was a disaster available where the satellite could get misaligned with the ground station and you have some nice crispy microwaved citizen sims.
The video of the Falcon 9 landing was a software stabilized video, if you noticed how the top of the frame moves down near the end.
So question, asuming that, that paper on betelgeuse is correct and it has "10s of years" left; wouldn't that mean that its already blown up and we're just waiting on the light of the explosion to reach us...
Maybe. Nobody knows for sure.
The rain in Spain stays mainly on the plain.
How are they transmitting the power to and from space? Wouldn't it be dangerous with more power, in case of some issues with the satellite or if something get in between?
Awesome story. Love your RUclips channel and what you do!! I learn so much!!! Boeing will get it figured out. Better to find out now than something happens on flight 😮. Great job as always
What would be the best way to beam energy? Signal going through storms, rain, wind, snow. But it seems a network of geostationary satellites with highly-efficient transmission of energy whether laser, microwave, radio...should give a nice boost to global grids.
*Solution to the "Time Light Problem"* The reason why people often stumble over the *assumption* that light years in outer space equals the same measure of distance and passage of time on earth is because general relativity is not being taken into account. In general relativity, the local rate of time and the measure of distance depend on the amount of matter or mass in the vicinity.
Locally, the rate of time and measure of distance doesn't change much inside of our galaxy. However, the distance in our line of sight between us and distant galaxies is extreme and running at a much faster rate of time as well as an expanded measure of distance outside our galaxy compared to where we are near Sagittarius A's Milky Way black hole (where our rate of time is much slower and our measure of distance is much more contracted).
The same way the earth appears flat locally, our universe also appears to be flat locally. However, over great distances throughout the universe there are differing measures of distance and differing rates of time from black holes to the lagrange points between black holes where there is very little acceleration compared to our relatively flat contracted local frames of reference near Sagittarius A.
When we observe other galaxies, we are effectively looking at vastly differing measures of time and distance relative to our local observations within the gravitational force of the mass of the Milky Way galaxy. This can lead to various observed phenomena as we look into outer space such as redshift, superluminal motion and the apparent faster motion of the outer spiral arms of galaxies. It's not the same as our flat observations of cats and dogs locally here on earth where we don't observe differing measures of distance and time.
So the supposed expansion of the universe, imaginary inflatons, invisible dark matter and dark energy or vacuum energy are *not* required to explain the observed redshift of light from distant galaxies or the faster than expected motion of the outer spiral arms of galaxies. As predicted by general relativity, the expanded space between galaxies due to the absence of matter in our line of sight where much less acceleration can explain the observed redshift without the need for a nonsensical universe expanding into oblivion for no apparent reason and it explains the faster than expected motion of structures and objects the farther it is from supermassive black holes.
It turns out that the vacuum energy of space is due to the frame dragging of black holes that are growing from gobbling up spacetime regardless of the amount of matter being consumed. Recent findings of a team of scientists have found that dark energy or vacuum energy is associated with supermassive black holes that are all growing in size, as opposed to an ever expanding universe. It turns out that light is blue shifted going into a gravitational well so the converse is true of being redshifted traveling great distances outside of gravitational wells.
Supermassive black holes are the most powerful forces in the universe with far reaching effects of gravity and vacuum energy. The problem and solution is that between galaxies, all of the galaxies all around are all together pulling and drawing in spacetime as well as exerting equal gravitational forces on empty space. This is the reason there is very little acceleration between galaxies and where there is expanded distance and a faster rate of time. The clocks are running faster outside of galaxies and the measuring sticks are larger meaning things are actually less distant than they appear. The more gravity drops off outside of the galaxy and in between galaxies, the more distance will be expanded and the faster the rate of time will be.
As predicted by general relativity, the expanded space between galaxies due to the absence of matter in our line of sight where there is less acceleration explains the observed redshift without the need for a nonsensical universe expanding into oblivion for no apparent reason at all. The differing rates of time and differing measures of distance also explain *how* a day is the same as a thousand years and a thousand years is the same as a day, at the same time in the same universe. 13.8 billion years is the same as 6,000 years and 6,000 years is the same as 13.8 billion years *within the same created universe!*
Being 73 I would not expect to be around to witness the supernova phenomenon of Betelgeuse...but what an absolute life experience that would be...terrifying but at the same time, the most fantastical, beautiful show the cosmos could ever provide us...🌃
Quite interesting, the contrast between our sentiment about it and that of a hypothetical civilization that exists within the kill zone..
About the perfect locked in view of Falcon 9 landing: several artifacts show that it's been digitally stabilized. First when the engine lights up, the rocket wobbles a bit. That means the view moved a bit and the shutter scan had an effect on the apparent size of the rocket. So it wobbled. Second, you can see the framing in top of the image when the rocket lands. That means the camera tracked too low. It was good, but it was not a perfect tracking.
Did anyone notice what looked like lightning on the Mars live stream at 17:38? About four frames have a moving flash but it would be really big, so it must be a glitch.

My new favorite drinking game is taking a shot every time Fraser says STRONOMERS... Send help!
Take care of your liver...
It's as live as it gets!
It's in your light cone, anyway.
Take a shot every time beteguise does something weird
14:40 it was theoretically possible before the test.
After the test it is known possible on small scale at least.
Possible isn't practical mind you.
I would also like to see it, but please... (my wishful thinking) during the Northern Winter. If it goes off in summer, we all be veeeery dissapointed!
NASA contracting with private companies completely killed the vibe. It’s like awesome space exploration, except now we’re making a few rich a-holes way more rich… for some reason… 😒
Would a Betelgeuse supernova be bright enough to make rainbows? I saw a 'moonbow' once, it was super cool!
Oh interesting, sure, if there were clouds high in the atmosphere, you'd see a supernova-bow. Whoa, but I wonder if you'd see different colours because it would be a different source of illumination. That's actually a mind-boggling question...
I need an answer to this in a big way.
@@frasercain How accurately could we predict the supernova if it were imminent? It would be amazing if we could see it as it happened.
@@arnelilleseter4755 time scale for C, Ne, O, Si are 1000 y, 3 y, 4m, 5d for a slightly more massive star. Core collapse is seconds . We should see it coming.
Rain bows we see on earth are not created in space, sunlight going through water vapor or rain causes them here, I would think that it's possible in space but temperatures for water in space is not conducive
have to remember too.. we arent seeing the star as it is now.. but as it was... ( however long ago determined from speed of light) whatever many years ago
it probably already did, its just the light has not reached us yet
Maybe, but there's no way to know without going faster than the speed of light.
❓ What are some of the best practices or tips that you would give to aspiring space & astronomy journalists❓How do you differentiate yourself from other space and astronomy journalists in terms of your style, approach, or perspective?
I'd also like to add that the JWST images of these earliest galaxies are beginning to show up on Galaxy Zoo for classification. If you're someone who likes astronomy and has some spare time, you might want to take a look.
(For those who don't know what I'm talking about, Galaxy Zoo relies on citizen scientists to classify galaxies and point out anything of note. Occasionally you'll see something really spectacular.)
That's fantastic. Many hands make light work.

Just spitting ideas. But it would be cool to know if, Jupiter being Jupiter had a collision with another smaller planet or other with a core. But it had a different density which is why there seems to be separation and influence on the surface scans.
When Betelgeuse does go supernova, will it appear as brightening over weeks and months, or will it just be like a giant lightbulb turned on in the sky?
It might be the brightest thing in the sky other than the Sun and Moon for a while. Not very much brighter than Venus on a good day though.
@@alangarland8571 but if it isn't brighter than Venus, it won't be visible during the day
It rained in Spain, were they on the plain?
So when will we see the 32-day JWST Ultra Deep Field?
Space based power might find a niche in solving the long haul electric aircraft problem. Battery technology might advance sufficiently to negate even that, but it's a use case where I can't think of an alternative power source that doesn't involve hybrid propulsion.
I was wondering if could we map the path of our galaxy could we look back at that region of space and see our own path space?
Was the rain in Spain falling mainly in the plains? 🤔
If the first stars in the early universe had much shorter lifespans and all formed about the same time, shouldn't there be a sweet spot in time where super novae happened with relatively common frequency? Is that something observed? Expected?
Rumor has it if you say Betelgeuse 3 times in a row it will explode!
14:45 I think it demonstrated it to be possible in practice, not just in theory, considering they did it. ;)
18:20 It's been stabilized in post, far less impressive of a feat than perfect tracking with a camera.
Still a pretty cool video though, even if my vfx-artist side is bothered by the shoddiness of the execution and the absolutely zero effort made to avoid the stabilization artifacts. :)
Yes, of course. Yeah, I should have realized that it was stabilized in post...
why will it become a pulsar ?
Re: Jupiter's blue spot... Is it possible that Jupiter has what could be described as a compound core where there are 2 or more large masses of heavy material rolling around each other? I would imagine such a configuration could exist if high mass or high density objects conjoined during the early formation of the planet without collapsing into each other.
Space based solar power good for polar orbit satellites, down to temporary science or military outposts where the extra infrastructure would be hard to bring. In the summer get power above the Arctic, 45 minutes later you're beaming it to Antarctica.
As everything is cyclical the old universe collapsed and boom, the big bang happened but this may have happened in multiple places and different times across the universe. It would be silly to think there was only one big bang. It would be like thinking there was only one galaxy or one star system. This concept would allow for differences in our thoughts on distance and time.
Hi Fraser,
Firstly thank you for all your hardwork! Your podcast makes long distance driving much more enjoyable with something interesting to listen too!
I’ve been wondering for a while, have we been thinking about terraforming all wrong.
Shouldn’t we be focusing on “bio-forming” . So instead of trying to make a planet like earth, we make a dynamic ecosystem which is setup for organisms on that specific world. Such as creating a biosphere on Mars which creates its own magnetosphere via bio-magnetism.
Is this all gobbledygook or actually feasible?
Thanks, Ophir
I can't think of how an organism could generate a magnetic field that's equivalent to a 1000 km ball of spinning metal. But it could help produce an atmosphere that would help block the radiation.
Hi Fraser love your content as always. Everywhere we look in space we detect CMB. Any chance that is what is pushing the expansion of the universe?? Inside of dark energy as we think?
What NASA could do regarding Starliner's electrical cabling and its flammable insulation is to paint all the cables with West System epoxy, the hardest and toughest epoxy in the universe (used for boats and canoes), and absolutely non-flammable. Far cheaper than having to redo the wiring, and far easier than to wrap anything around the cables; and probably far safer, as a wrapping would leave gaps, while a couple of coats of epoxy will probably not leave even a single point of exposed flammable material.
I wonder about the additional weight?
@@frasercain This WS epoxy is pretty light, in spite of its amazing strength. I know because when I've used it I often had a glassful of mixed liquid left-over, which solidified in the plastic cup or whatever I mixed it in, and then it hardened and I kept it as a souvenir, and it is definitely lighter than water. And thinking about this in comparative terms, the solution that NASA considered, of over-wrapping all the cables, THAT would definitely add more weight than a coat or two of this epoxy varnish. To get to a millimeter thickness, as used to bullet-proof those kayaks for navigating rocky rapids, for example, it takes about 10 coats of the stuff.
This solution would be superior, in that a manual over-wrap would leave gaps, whereas painting with epoxy, specially a double-coat, would not leave even a point anywhere of exposed flammable material. Additionally, WS epoxy is the toughest in the world, famous for it, and so doing this would strengthen all the cabling against accelerations, vibration and whatnot.
I left a message for NASA through their website Contact; I hope they read it and consider it.
EDIT: Been looking for density info on West System epoxy, but can't find density data. However, suffice it to say that this epoxy does not "want" to be applied thickly; it "slowly runs", pardon the oxymoronic sound... This is counterintuitive because it is quite viscous, which one might incorrectly assume to imply something about surface tension ... West System epoxy has almost zero surface tension; it flows slowly but it flows steadily. If you paint it on top of a wooden surface with a thin crack, it will slowly but steadily penetrate the crack and start dripping from the underside. Painting cables with it, and trying to be "generous" with it, would probably result in the stuff dribbling down the cable to the lowest point and dripping from there; so it kind of forces you to apply it thinly for it to NOT do that.
Might be a series of micro novas , could go on foe a very long time ?
Using entangled particles for point-to-point audio particles
The camera shacked a lot, but they stabilized the video, you tell for the black bar at the end of the landing sequence, Still a great video.
