Binary rogue planets orbiting each other and not stars is a new phenomena I have never heard of, thanks Becky, good to know new discoveries are being made even with exoplanets too✌️❤️🇬🇧
@@mal2kscMore likely theories about how such objects can form are either wrong or inadequate. One pair can be accidental, many pairs are not. Whatever is happening appears to be pretty common and normal.
Thanks Dr Becky. I watch your channel with my Grandson. We spend hours talking about and investigating the topics you cover. It’s so exciting for me to see him so enthused by your videos. We both like forward to your next edition. Thank you so much. Peter.
I feel like those attosecond pulses would have been useful for my university thesis (tracking the movement of proteins in a cell. The experiment failed because we couldn't record them fast enough, the motion just looked like a random mess)
The more I see if your INCREDIBLE monthly videos the more 1) I look forward to the next one, 2) I get more interested in astrophysics thanks to your wonderful explanations and 3) WHY DON'T WE HAVE THIS FOR BASICALLY EVERY SCIENTIFIC AREA OF STUDY? Would love to have hours of monthly videos summarizing very technical modern scientific discoveries. Cheers Becky, you're showing everyone the way!
You might like This Week in Virology, available on YT or as a podcast. Most eps are a group of virology experts discussing latest paper/s for 1-2 hours - so more long winded than Dr Becky... they are timestamped at least. There's a huge archive of 1000+ episodes, covering a wide range of topics; and plenty on COVID of course. Also a free lecture course that gets updated every January. I've learned a lot from TWIV despite dropping formal Biology education at 16 so I can highly recommend 🙂They also have sister podcasts about microbiology, parasites, neuroscience, the immune system, evolution, etc(?) which I haven't really gone into because there's so much content just on viruses and I honestly haven't found the time!
Just taking a moment to thank you again Dr.Becky for taking the time out to produce this video! I know when I say we all are grateful for the professional insight you bring to us! 🙂
Thanks Dr. Becky! You have such an amazing skill for communicating complex concepts across such different expertise levels without ‘talking down’. Always looking forward to the new news 🥰
I can't believe there won't be a Dr. Becky video for one or even TWO weeks!! You're wonderful explanations of complex topics and fun, enthusiastic videos are one of the highlights of my week.
Watching the live retrieval and reveal of the Benu samples reminded me of being in middle school at Chabot Space and Science Center on the day that Spirit and Opportunity landed on Mars
I was fortunate to be right in the middle of the last annular solar eclipse that happened in Brazil in 199(7?, I'm not sure) and this one Saturday, thought it will be only partially visible where I live will be a bit more special because it's my birthday as well :)
To me its always more exciting when we find something we can not yet explain as oppose to finding evidence for a prediction. still both are very exciting.
I had my HA telescope all ready for the annular eclipse only to be clouded out here in Northern California. Disapointing, but there is always next year!
We definitely get dust devils that get tall in New Mexico. I've seen some that were nearly a half mile wide too. Not going to say they have been 2km, but you can see them from Miles away and they still look tall.
Becky casually singing Light Years by The National's in the outtakes and taking me completely by surprise. It was one of my favourites of theirs, then I figured out what it might be about and was devastated and couldn't listen to it for ages, and then I dug a layer deeper and managed to reconcile with it. It's a beautiful song.
This is the content I come to see. 30 quality minutes with NSN and Dr. Becky. No fluff, no gimmicks, just straight up appreciation for the universe :D Oh, and 27:03 missed a chance to say "JUMBO problem for our models". I woulda fell out of my chair if you had.
17:45 - I was confused at first that you said "GIza" (like Egypt), then figured you said geyser a few moments after. Looked it up, and today I learned in the UK geyser is pronounced that way!
I used to participate in BINAST (Binary Asteroid project) as an observer (data collector not a scientist). Binary Asteroids are far more abundant than were first thought. One of the leading theories for their existence (I am summarizing as a layman) is where mass is sloffed off a fast spinning object and 'captured' in orbit for those asteroids that are effectively just held together by gravity. Given these 'failed' stars are just held together by gravity and are very hot, why could a similar mechanism account for them?
I've been in love with phyics and astronomy since I was 15 but never got a chance to study in college. You do a great job in describing things. Wonderful job
Loved that you demonstrated the three finger technique, Dr. Becky! Usually, folks just say what to do. A live demonstration... caught me offguard, goodly so! (I know that isn't an actual word.) Are the book sales doing well?
I'm sad that it's supposed to be completely overcast for the region I live in for the eclipse. It's only going to be a 50% coverage eclipse but that's still very cool and very rare. I got a filter for my telescope and binoculars to be able to look at it but then saw it's supposed to be rainy. Sucks when the clouds ruin one of only a handful of chances I'll have in my life to see an eclipse.
I expected antimatter to fall "down" because gravity is not understood to be a charged force that can have poles. Its a result of curvature in spacetime, and the resulting time dilation involved. Its cool that this has been confirmed.
I watched the orionids with my coworkers once. The once every 3-6 minutes frequency really tested everyone's patience! At least we saw a few streaks of light.
The dust-disks and 'coffee stains' around those stars is SO COOL! I want to break into the spectroscopy of those and dig into that data kinda bad! All of that is so neat. The binary planets thing is also so tantalizing. Someone is likely crunching a big data set right now trying to find a best fit model to explain that.
I can understand double rogue planets-- they would probably not be ejected planets (the gravitational movement would make capture difficult, and if one of a double is ejected, the other should be sent inwards), but form directly from a nebula collapse that wasn't big enough to produce brown dwarfs, but otherwise akin to stellar creation. The difficulty is that, in the Orion Nebula, we shouldn't have small bits to collapse down like that. There's just so much more star creation, and their gravitational wells ought to disrupt or even capture small clouds like that.
@Dr_Becky Isn't that red colour of the Moon due to blue being scattered by the atmosphere and thus being effectively filtered out, leaving more red? The same effect causing a sunrise and sunset to be reddish?
I live right under the path of the shadow path Looking forward to it. Never was good at the higher maths, but astrophysics has always been a fascination of mine. Keep up the good work, love your content
my first video, 5 minutes in and I already love your content! thank you so much for your hard work and for presenting informative, relevant and up to date news in a simple and entertaining way! I am so thankful you share your knowledge with us
Imagine if we see 3 rogue planets orbiting each other. I know it’s technically not possible and if it’s it’s not long lasting, but still that would be awesome
I was a bit surprised to see Durham NC as a reference point for the Stellariam graphic. Makes sense for an academic to travel here but it was a bit unexpected!
Absolutely awesome post Dr becky , stunned by the news of rouge planets but very puzzling as to why so many binaries systems , this really tickles my fancy , I have watched orion for decades now as it's my fav but now even more so , if there are so many free floating planets in such a small area , can we assume this may be typical of most nebula systems ?
One thing you did not mention is that the 43 attosecond laser is still off by a factor of about 5 from actually being able to probe the movement of electrons.
She's a very beautiful woman AND highly intelligent. What's not to like? I have always been attracted to intelligence. I enjoy intelligent conversations
mike brown was one of my inspirations to study astronomy!!! i'm currently a student researcher at the national radio astronomy observatory in virginia. i'm so happy to see his name on a recent paper!!!
Dr. Becky, I live in NY state and will BARELY experience anything from the Annular eclipse that is coming up soon. This got me interested, however, so I looked up coming eclipses and don't ya know: NY state will experience Totality on April 8th 2024!!! Next Year!!! That's one HUGE check off from my bucket list! Thanks, Dr. Becky, you rock!
Ok, I decided to give it a shot. Why are binaries more common on the low and high ends, but less in the middle? Why the bimodal distribution? That kind of bimodal distribution really wreaks of their being two different binary formation mechanisms at play. One could be in situ formation, and the other could be chance random encounter. Larger objects like stars might be more prone to form binaries by in-situ formation simply because they're formed in regions with more mass available. But smaller objects, like planets, might be more prone to form binaries due to chance encounters in their original formation nebulae. Why? Perhaps the good old square-cubed law. The only way two objects, formed separately, will ever be able to form a binary is if they get close enough together, at a low enough relative velocity, and then can lose enough velocity, while they're close enough, to become bound to one another. But think about gravitational attraction and gaseous friction. First, with gravitational attraction, more massive objects should accelerate to higher relative speeds than smaller objects as they come close to one another. The more massive a pair of objects, the faster their gravity will pull them as they accelerate inward. Two person-mass objects flying close to each other will barely perturb each other at all. Two neutron stars flying towards each other will accelerate each other to relativistic speeds. Larger objects, in a random encounter, will accelerate each other more as they fall in, providing more relative velocity that needs to be bled off to produce a capture event. Then think about gaseous friction. These encounters are likely occurring in dense nebula. For two objects encountering each other to be bound, they need to lose relative velocity. And to do that, they need to be slowed down. Short of a gravitational interaction with a third object, the only way this can happen is via friction with the surrounding gas. And the smaller the object, the easier it is to slow it down via friction. Friction is proportional to surface area, while kinetic energy is proportional to mass or volume. This might explain the bimodal distribution of binaries. On the heavy end, in-situ binary formation dominates, and you have more binaries forming simply because there is more mass available in regions of formation. On the light end, chance encounters dominate binary formation. And lighter objects are more prone to capture via chance encounter than heavy ones, as heavier objects produce a greater infalling increase of velocity, and smaller objects are easier to slow down via gaseous friction/drag.
As a glider pilot from down under, a 2km high dust devil is pretty common. That's only about 7000 feet. On the huge days here, you'll be flying is heavy dust and chaff above 10000 feet
Hello. By the way, I have difficulty communicating because I had a stroke in Broca’s area, the part of the brain that controls speech. 2/8/2021 but I lived again. (My wife helped me compose this.)
Thanks for the excellent work you do to keep me informed! Can I make a small critique? You edit your videos to compress the empty space between certain sentences. I know that a lot of youtubers do this. I really prefer a more natural speaking cadence throughout the video. But again, thanks for all you do!
Two possible topics for a future video: Tom Scott recently released a fascinating video about the Very Large and Extremely Large telescopes. Among other things, he discussed the interferometer capability and shared his opinion that the ELT would be the largest optical telescope ever built. Would you talk about the interferometer, and in particular its research results to date (I'm not aware of any, but I'm not as plugged in as you are). Second, what is your opinion on whether there will ever be a larger ground based optical / infrared telescope than the 40 m ELT?
Interesting that the dust devil on Mars isn't dense enough to see much beyond the base (although that was a fairly large base) but still dense enough to cast a shadow up high
I'm from Melbourne Australia and Andromeda is in our northern sky right now. I use Stellarium to locate it but the light pollution makes it hard to see in real life.

Binaries usually orbit one another, so rotating would be rather odd
They're not rogue yet, but Pluto and Charon are also a binary planet system
Welcome to last week, lol. Other channels have been talking about it for a while.
@@mal2kscMore likely theories about how such objects can form are either wrong or inadequate. One pair can be accidental, many pairs are not. Whatever is happening appears to be pretty common and normal.
It's a pretty obvious one though right? There have to be billions more rogue planets than those in solar systems, it's just an obvious numbers game

I feel like those attosecond pulses would have been useful for my university thesis (tracking the movement of proteins in a cell. The experiment failed because we couldn't record them fast enough, the motion just looked like a random mess)
atto second is probably too fast and hot
That sounds like a cool thesis
Isn’t electron microscope scanning destructive by nature, and something like proteins would be too damaged in just a few pulses?
Imagine if you got sidetracked in your experiment and invented those fast light pulses before they did 😅✌️
Human chemistry is amazing. Some critical protein configurations last only seconds

Finding stuff we can't explain is my favorite part of science. I think it provides a healthy dose of humility.
Interesting that the dust devil on Mars isn't dense enough to see much beyond the base (although that was a fairly large base) but still dense enough to cast a shadow up high
I'm from Melbourne Australia and Andromeda is in our northern sky right now. I use Stellarium to locate it but the light pollution makes it hard to see in real life.
love your videos and the way you explain things. you are the best at it. but your mic was driving me crazy in this video
Love the news! Enjoy your vacations!
