46 views and only 6 likes?, what the hell is wrong with people? This is a kickass channel John and I really appreciate the work that you put into it. You keep us posted on the latest in science without dumbing it down. And perhaps the best feature is that you don't use the robo-voice crap, your narration is spot on! How's that new project coming along?, just a hint...please?
No robovoice ever! I hate those channels. It's always going to be me or a fill in if I'm sick. And, looking like August for the debut of the new project. I can tease a bit about it; similar content and topics, it's me after all, ... but live with MUCH longer run times.
Thanks for the update, really looking forward to it! Btw, speaking of methane, have you seen the new pics of "methane dunes" on Pluto? Really cool stuff.
cant hit like on some phones
Greg Brockway it's a RUclips algorithm thing. It catches up later with views and likes
I of course love your videos for their great content but I also play your videos at night when I'm trying to sleep. You've got one of the most relaxing voices I've heard and send me to sleep so I have to watch again in the morning. John Michael Godier, educating us and curing insomnia at the same time! A major talent.
The idea that life formed on Mars then came to Earth still leaves the question open, how does life originate?
That first step is a biggie...
From a vagina.
It also gives us plenty of new and completely different environments to consider when we try to find an answer to that question.
Life originate from a dead planet is stupid idea
ww3 Fire - it indeed is. The idea is, however, that Mars wasn't all that dead when life arose billions of years ago so it's not as stupid as it seems.
Of all the videos I've watched in the last couple days about recent discoveries related to life on Mars, this is the most informative, knowledgeable, and grounded. Thanks, John.
Haha, it'll be like, "where's JMG?" "I dunno, last I saw he was Lysoling a rock."
Dudes, if we found alien organic molecules in our small solar system, imagine what's out there.
MegaSlothGhost It still doesn't deal with exceptionalism, since a unique event could have occurred on Venus, Earth or Mars and one of the three contaminated the others.
We are the aliens. We are the proof of life evolving.
Isn't the point of panspemia(?) that its not a question of whether life arose on either Earth or Mars but that it could also have arisen from elsewhere in the Galaxy. If Mars life is related to Earth life then it could also support the idea that this solar system was bombarded with Archaia from who knows where and it found a foothold on both planets, only one of which went on to flourish.
I've mostly heard of it as the idea that life could be seeded by asteroids and such from planet to planet, I'm not aware of any other factors required for panspermia. Could be both I think. But if there's actually life on mars, then I hope it's because of "local" panspermia. I'm too terrified by the idea of the fermi paradox to want something else.
Most likely our solar system was seeded with life from the galaxy. Proving this is a big step though. I would be shocked if Mars life is extinct and unrelated.
BLAIR M Schirmer "great filter" Evidence of lots of ancient primitive life is not bad news for humanity. There are lots of hurdles between primitive life and space faring civilization.
Now, if we found loads of radioactive ruins of advanced civilizations everywhere that would be terrible news. It would suggest that all the hurdles between abiogenesis and technological civilization were easy but something about technology is always fatal.
Yes Isn't the idea of "hard panspermia" - Wickramasinge and Hoyle - that life arose ins space itself along with the rest of the stuff we see, and that such "spores" can give us colds (viruses) as they are continually raining down. It may have seeded both earth and mars and many other places. Alternatively abiogenesis (life evolving from non-life) may have happened - maybe more than once and independently. Worse, these ideas are not mutually exclusive. I guess we don't know but ideas of panspermia are certainly more respectable these days. And of course we have to define "life".
Correct. Life could be relatively common in the form of simple lifeforms that, over the span of cosmic time, is moving all over the galaxy and universe. The possibility that life in our solar system came from a distant solar system is highly likely compared to Mars or simply Earth. Not proven in any way, clearly lots of assumptions, but as far as the panspermia theory goes, it's not so much about planet to planet exclusively.
Let’s hope we can devote more resources into more probing
my ass can only take so much
that's what she said.
Mayor of Big Daddy’s Pizza That's what she said.
Don't worry, there are plenty of resources going into an ever increasing amount of probing... in the bedroom.
More probing = more life.
I've been on youtube for nearly 12 years and mate you produce some damn good stuff. Heard a blurb of this subject this morning but make it so eloquent and easy to access, appreciate mate. Been with ya since
Congratulations on the effective, unbiased presentation of the findings and your accumulation of past and present research in order to construct an exceptionally interesting case for life on Mars.
Unfortunate if Curiosity ran over last living Martian. oops
If Martians reproduced sexually then euthanizing the last specimen would have been a mercy.
Viking had crushed the rest
Fresh Martian roadkill right there.
Probably not too tasty, but certainly one of a kind!
Don't worry, it only kills cats.
+Lenard Segnitz so if you're the last human on earth; you would like to some exterrestrial come and kill you ? :P
longtime sub here i love these videos you really put time into them and make it easy to follow whats being talked about its only a matter of time until this channel blows up keep up the great work and ill always promote this channel the best i can! thanks John
Wow JMG! Nice job putting that one together so quickly after the news release. This channel is such a nice compliment to my news feed and I'm always pleased when I see a notification of a new JMG video pop up.
I'm sending a link of your channel to the guys who do the NPR show, Radio Lab. Maybe they'll do a segment on you, or better yet, collaborate with you to produce more amazing science content.
That last bit gave me chills.
As per usual, informative, interesting and a classic voice! Thanks John!
"Last I saw he was Lysol-ing a rock." OK, that more than makes up for your last vid's weak closing joke, this one's another All-Time Classic!
Ancestral Homeworld sounds like a nice title for a book on the reconquering of Mars!
Thanks for the update. Appreciate the work you put into your videos, they’re are very informative without being sensationalistic.
I recall a documentary on the early Mars landers and a scientist describing the experiment he designed to search for life. Even after all these years you could hear the frustration in his voice over the experiment being positive but the scientific community writing it off.
It's out there. I believe that it's quite likely that life is everywhere, even places we don't think are hospitable.
I just hope they tell us when they find it.
Our track record, where in our "certain knowledge, life is impossible" here on Earth is none too stellar. Even in (relatively) recent history life has been found to thrive, let alone survive, in environments we deemed "far too hostile".
We are far too Earth - centric. Life almost certainly does NOT "Need" Earth-like environmental conditions, only life that evolved on Earth. Life on other Worlds will be suited to their conditions, and though strange by our very narrow standards, may well be very capable and possibly advanced life.
Phil S , I think you're right. Life is likely everywhere and possibly completely different from the life on Earth.
There's a huge difference between life being capable of adapting to all kinds of habitats and life arising somewhere. The conditions and limitations as to where life can exist are reasonably well known today. The conditions required for life to arise on the other hand, are an unsolved mystery.
Thank you for all you do
Always Gold to be found here
another great video. very informative and obviously well written. keep up the good work!
Love your channel, man!
I usually don't find myself laughing at your videos but the "Lysoling a rock" comment caught me by surprise :-)
Another great vid. Keep 'em coming!
Either way, the discovery of life on Mars would have massive implications for the probability of life elsewhere in the cosmos. If life emerged on two planets independently in the same solar system then it implies that life arises anywhere with the right conditions and is common. If panspermia is true then it implies that life has been spred across the universe and is common.
It also has Fermi paradox implications. If the emergence of life isn't some incredibly improbable occurrence, then the supposed rarity of abiogenesis can't be the explanation for why we don't see extraterrestrial civilizations.
Alex M Not necessarily. It could be that life arose in one spot in the solar system and contaminated the neighbouring bodies. This would mean that it could travel those distances but not necessarily interstellar space.
Instead of terrestrial exceptionalism, you end up with solar system exceptionalism. We really need to find life in other systems for the idea to hold up better.
Otherwise we could be dealing with an exceptionally rare or even unique event within our system.
I suspect any Martian and Terrestrial life could well be distantly related, as could the alleged microbes in the Venusian atmosphere.
Still plenty of great filter hurdles between abiogenesis and technological civilization. Now if we found lots of technological ruins everywhere then humanity would be getting terrible news... the great filter is still in front of us.
+Lenard Segnitz RUclips comments war is the great filter, bitch.
Somehow I knew I could expect an immediate vid on this announcement. With all of this news, I feel like any manned mission to Mars trying to search for life would have an answer in under a week of landing.
Exciting stuff ladies and gentlemen,...exciting times.
Yet another fine presentation. 👍
this stuff gets me hyped up
Thanks for another great video! I look forward to them every week. You should see if you could narrate a show on the Science channel. :)
Great stuff.
As Greg said, great channel, thanks!
I wish I could've seen Mars 3.5 million years ago. I bet it was beautiful.
This is the most significant finding of its type to date IMO.
'WHere's JMG?'
'I dunno last i saw he was lysoling a rock.'
pffft.
Great stuff! I'm anxious for a manned mission to the red planet to try to solve some of these mysteries!
This should be a bigger story in the national media. I'm quite sure NASA will make a definitive announcement about life on Mars soon.
Came to John's post for the real deal about Mars.
3:45 That hit me hard.
Clearly what is needed is more exploration. Lots and lots of exploration. More robots, human expeditions, fine gentlemen in space suits styled after Victorian garb tromping across the Martian landscape and having tea in between exciting excursions to obtain fossils in the name of the Queen.
The unexpected things you learn. Until now, I didn't know "Lysol" is a verb.
I love this channel. The fact you have less than 20,000 views tells me humanity is doomed. But I'll enjoy every video you make until the Aliens come to kill us in revenge for "Reality TV".
Awesome video JMG!
Lysoling a rock... oof. This puff is for you John. Thanks for the mind benders
i hope i don't see anybody yelling first
JoinAnamoly first!
Shut it pimp
This post is equally as futile as any "first" Comment.
hopefully they find a trace of the cavs still having a chance to win the series
I like all your "currently"s.
Its possibly an intergalactic heritage site ..and were driving all over it !
peter lewis Terrians have no manners *rolls eyes
So exciting!!!!! Organic material, confirmed. Methane present, confirmed but not sure why. Microbe fossil maybe.
Wow it’s kinda painting the picture by its self now.
It could just mean that Mars is a toilet, a rest-stop on some lonely galactic highway.
Thanks for this video Jean-Michel, keep us up to date with this sort of thing, thanks again and keep up the good work.
There are other eplanations for Martian DNA resembling Terrestrial DNA (if this were found to be so), Terrestrial life and Martian life could have the same orgins but these origins are elsewhere other than Earth or Mars.OR maybe that early Martian and Terrestrial conditions were suffiently similar for life to have evolved similarly in parallel. OR it could be that the DNA of carbon based life forms always resembles eaach other for some reason.
Lysol a rock!
I met one of the scientists that handles the driving and pictures taken by the rover.
One big problem with complex life evolving on earth, (and one any biologist will admit to), is that 99% of of its evolution most likely took place between 'dirt' and simple single cell organisms. In other words, just getting from 'dirt' to one celled creatures was by far the biggest step in evolution. Once one cell creatures existed, the rest was fairly easy from an evolutionary standpoint. But...then it begs the question, if the earth is only 4.5 billion years old, how could this be? We know that 1 billion years ago we had only one celled creatures. SO how is it that 99% of evolution occurred prior to 1 billion years ago? This is one of the main arguments for the idea life came here from outside earth.
John, would you ever talk about the cost, logistics and risk that would take for a manned mission to Mars? With discoveries like this it could be a boost for that sort of mission but I don't know with humans can survive being that long in deep space.
No wonder we destroy so many things! We are children of the god of war!
Like... Cheers John. Regards G
Tantalising but positive confirmation is needed before we can break out the champagne. If some form of microbial life still exists on Mars it most likely will be restricted to certain areas of the planet such as the poles or the equator and in most cases be buried quite deep in the equivalent of Martian geothermal vents, as on Earth. I suppose we'll never know for sure until a more comprehensive survey can be done on a much larger scale involving probes taking random core samples from the different types of rock that exist there and analysing them in minute detail and combining that by placing remote sensing devices under the Martian soil, together with satellites placed in geostationary orbit, that monitor specific areas continuously for signs of microbial life or other activity that might provide further, circumstantial evidence where direct evidence is lacking.
So you're saying there will be champagne... just not yet? What moment exactly do they open the champagne?
*Interesting!*
Mars has a large intelligent insectoid colony that was soft disclosure in the John Carter Between Two Worlds move.
If genetically distinct from Earth mind blown
If genetically linked to Earth mind blown
It's exciting either way if there is or was microbial life. Like he mentioned, if it is related to us then Panspermia is true and may in fact happen over even larger distances.
If it is completed unrelated then life may be common throughout the galaxy. If life arised independently twice in our solar system then it is likely easier than we thought.
I'm not sure if the 0, 1, infinity rule applies here but I've heard it said before that certain events either never happen (0), happen once by fluke (1) or are common (infinity). For it to happen twice in our tiny patch of the galaxy and nowhere else doesn't seem right and would go against this rule.
I think it very likely that basic simple single cell life will be found in almost every solar system with a rocky and watery planet or planets in the given star's goldilocks zone. Finding intelligent life is going to be exceedingly rare due to the many things that have to happen just right to produce such life. Of course considering the shear numbers of solar systems in the universe. It is thus likely that Mother Nature probably has several billion or more of the solar system laboratories with a star and planet that had/have the pre-requisite starting conditions for allowing single celled basic life to take hold and then evolve into intelligent human like creatures. And I say human like because form tends to follow function; on a planet where intelligent creatures are created eventually they'll have to do the same things our ancestors had to do on earth to survive i.e., learn to protect themselves against predators by learning to make and use weapons and tools etc...etc... so I suspect throughout the universe with planets similar to earth where intelligent life has evolved, there is the likelihood that the same basic floor plan will be used by nature - (bi-pedal, arms and hands with opposing thumbs or some form thereof) - and evolution there, while it will not take the same path as here, or anywhere else for that matter due to local evolutionary conditions, but will take a basic similar path. IMHO
That Methane is the rover sniffing it's own farts. Well back to the drawing board.
I'm still holding out hope that we will one day find intelligent life on Earth.
There is a problem though: If we find evidence of life, how exactly would we determine, if it is related to earth life? Which aspects of life can be unique to a single origin and which are a necessary consequence of basic chemistry? For example: If we find out, life on Mars is(or was) based on RNA or DNA, that could mean that either the lifeforms are related or that RNA is just the most likely molecule to be used for genetic encoding due to its superior suitability for this task.
What exciting news! I dig it! ☆
I love your content, I'm always captured by the subject matter but could you read the script just a little less quickly? It'll feel less like a bulletin, and therefore not only have greater appeal but be more understandable for those not as sharp witted as yourself. Keep up the great content!
If I was you John, I'd go by JMG all the time. Look how well NPH is working for Neil Patrick Harris...
Methane seeps are also responsible for non-photosynthetic ecosystems in the deep sea. This is exciting news.
great video !
keep it up ! :p
The Earth vs Mars Chess playoff still on hold?
If panspermia did occur, we don't know that Earth or Mars was the location of orgin; it could have been somewhere else entirely.
Venus is the most likely location other than Earth or Mars. Early in its history (~4 billion years ago) it had a much more hospitable climate and probably oceans on its surface.
It would be really cool if anywhere life could form it does and it isn’t rare at all. I bet that’s the case
Any life on Mars would be more than likely to be genetically related to life on Earth. The two planets must have exchanged billions of tons of rocks over the past 4.5 billion years or so through asteroid impacts carrying building blocks of life back and forth.
I think there is life there. Something is creating methane too. It might be too hard to find though with current tech.
Not sure why the origin of life should be confined to Earth or Mars if panspermia is really a thing, so playing a bit of devil's advocate are we? Love these Mars updates :)
I want Heinlein's Martians!
The methane gases coming from the ground are coming from sewage vents from underground cities!
Wow this is amazing.. this is indeed a weird, fascinating and wonderful universe, in which we are just getting started. Good day, Earthlings, Martians and Venusians!!
The one reason I wouldn't want to go to be the first on mars Perchlorates. (I hope I spelled that right.) Mars is low gravity though so I wanna go skate there even if it was tricky to get used to.
Also once there was a decent atmosphere on mars would it be low enough gravity to be able to fly with a modified wingsuit?
I always have wanted to go to venus. Imagine we could live in the atmosphere for a while concentrate on learning how to reverse run away global warming. This would give us time to fix what is going on here as well. Great job today JMG
What if there is a complex subterranean ecosystem?
Excellent as always, but why would panspermia be limited to only Earth and Mars? Isn't is possible humanity hitched a ride a billion years ago from elsewhere?
JMG, have you postulated on electrical or plasma discharge being the source of many crater forms we see? Does this hint that an advanced propulsion system need not carry fuel but rather harvests potentials?
They've known about life being on Mars for years.
Lewis Viking certainly suggested that there could be life there but the results were written off. Microbial life could be common.
I suspect most of it is subsurface. Maybe we need to look for life under Mars not on it. We have a lot of underground microbial life here on Earth.
*_...did you forget the 'organic' twin-stiped mushrooms (not a Rhawn Joseph Apothecium)..._*
Do we know that the organic molecules on Mars were generated there? Or are we just looking at an ancient comet impact site? I believe Rosetta did find complex organic molecules on 67P. And Gale Crater, where Curiosity is rolling around, is a ... crater, an ancient impact site.
If life is found on Mars, and it didn't come from Earth, we can conclude that life is common in our galaxy..
Martin Andersen 😂 I just thought of something.. what if they located life but then realize that the microbes came from off of curiosity and not that it evolved on mars😂. That would be a total buzz kill
Shoot! I almost rocketed myself off the chair, and yet Johny speaks about ancient Mezopotamia;p... just kidding, it was obvious what is going on;)
Let's see if I understand this correctly. Four years after Curiosity left the bottom of Gayle Crater they notice that it detected organics? Four years? Why would it take 4 years? What was being done with the data for all that time? Makes one wonder how much other data is being sequestered.
Are they able to do a carbon-12 to carbon-14 ratio analysis?
Question: Have we absolutely and positively eliminated the existence of life on the Moon? It is possible the Moon has microbe in lava tubes, at the poles, or deep within?
Couldn't it also be that life originated elsewhere and migrated to both Earth and Mars?
How often do you get the chance to say, tantalizing ?
And he used it twice .
On such a hostile planet what are the chances that organic materials would assemble (and remain complexly assembled) for life to arise? I think people are too biased about this question. If lifeforms aren't detectable among all those stars out there -- why would we would expect to find it on Mars? Because if we did find it on Mars that would probably mean that primitive lifeforms are everywhere. Do we believe that?
I just thought about what if life can arise only in planets having the conditions Mars had back then, but then it can only evolve to what it is now on Earth in planets having Earth's conditions? It will throw the rare Earth theory, and many theories away because now life will be needing TWO planets, and then panspermia. So, even a rarer path for life to reach intelligence.
Also consider our Solar System if Mars and Venus were swapped around. Mmars is currently on the outer edge of the Circumstellar Habitability Zone, so a larger planet that can better hold its atmosphere might have been able to keep any life that arose early in the Solar Systems history and would now have a head start as the planet warmed as Sol heats up again.
Do you have a FB group/page?
I'd like to follow it
LMFAO @4:00
Yeah, we'll teach them to possibly be where we came from!
Can’t wait to see the fish fossil
Find any banths or kaldanes yet?
Mars being the origin of life on Earth might have the opposite implications than we might expect on the Fermi paradox. Mars would have been a friendlier environment for life than Earth was around 3.7 billion years ago. Maybe life needs more time than it normally gets on a single planet.
Would it ? Mars is still outside of the habitable zone and 4.5. bya the sun's solar radiation was roughly 30% weaker, so mars was a lot colder than it is now. Further is Mars a lot smaller than earth, so it has a lot less gravity, meaning atmospheric pressure has always been much lower than on earth, meaning fluids will easily boil away (which is why there is not a lot of water left on Mars).
Looking for life on mars is like the drunk looking for his keys around a street light, despite having them lost somewhere else, because that's the most convenient place to look.
The likelihood of extraterrestrial life in the solar system is pretty close to zero, but IF there is, then probabilities are a lot higher on iovian moons.
