I'm 72 years old and it makes me happy to see wonderful young people who are making the world a better place.
Wonderful person bringing wonderful news in this daily mundane life.
I love you.
Look within to detach from the mundane. There’s so many amazing things to discover there! 😊
As far as you know.
One day I think we'll be finding planets with habitable atmospheres all the time. Just like we went from not knowing about other planets to knowing there are billions of them
Most people interested in this stuff read it as NASA publishes it. What you get here is at best a couple weeks old.
You "KNOW" there are billions? Or just ASSUMING there are? Don't like science much do ya?
@@user-oh2zx6kk2u Oh, LA DEE DAA....
@@dcpackreally dood?
@@user-oh2zx6kk2u Most of the stuff here is confirmed, and well researched. Other people upload 30 minutes after nasa declassifies a finding with out knowing anything is confirmed about it. Some people do it for the money, some people do it to spread the truth.
I love this guy. Where else are you going to learn something new almost everyday from someone who does his best to keep it real. Right here kids. Cheers.
Cheers 🎉
The fact that this planet is so close to us and already contains such promising features feels like a great sign for things to come
I do not want to shake hands with the magma people
@@akd8525 Weren't they called Lithoids or Silicoids?
Well, I guess “close” is a relative term.
@@oberonpanopticon Yup! There are only around ~200 subgiant/giant stars within 100ly of Sol. For a planet to have that many terrestrial features so close really feels astonishing! Maybe those magma-people aren't too far after all :p
well get that "fact" out of your head, we will never leave this planet.
That JWST is pretty awesome! And so is Anton! Thank you Anton
I'm amazed at the scientific advances that have occurred in my lifetime. I'm 66 YO and remember the day they landed on the moon. Now to see what the JWTS is finding it incredible. I can hardly wait to see what will happen in the next 25 years, and yes, I do plan on being around that long, lol
Best of luck and good health.
It is likely we might live to see the colonisation of the Moon, at the very least
mostly just those in the countries most responsible for global warming and polluting can plan to be safe that long, so... gross.
@@Poodleinacanhopefully Mars in 10 years.
You’ll be 91, it’s definitely possible, just eat healthy, sleep, laugh with your family.
They landed on the moon??? You sure ?
At times I wonder if on a distant planet there are Astromers looking at our atmosphere wondering if earth support life.
I wonder if in another Galaxy if there's an Alien Anton saying " NO IT'S NOT ALIENS, NOT THIS TIME BUT ONE DAY !! " Maybe not there's only one Wonderful Anton. Have a great week everyone. PEACE AND LOVE TO EVERYONE ❤❤.
When they or us see a planet with life, it will likely be dead as 100s of millions of years of light travelling
In reality, the odds are probably fairly good that humans are perhaps the only sentient, technologically intelligent life forms that likely exist at this time in the entire universe.
@@rolandblock2530 Wrong, we can only see planets close to us, they have to be at least in our milky way and the longest distance is 100k light years.
It's very unlikely, the time span is very short to look at something. Other planets have life living either in the stone age or are way more advanced than humans.
Anton, you are by far my favorite science explainer. Please never stop making awesome videos.
Yes Anton and Anton please start addressing the most important issue in science ever that we are being visited by a non human intelligence and that the government admitted this and we even have recovered their technology, this topic is no longer taboo, but these so called scientists are too biased out of fear or ignorance to do the research
One day we will be an interstellar species. So exciting
Considering that we are made of stardust, technically we already are.
If we survive to see "one day."
Yes we already are.
Lets see if we make it so far til we become interstellar species or if we blow ourselfs up to planetdust
@@idrisyakubi1015 Probably doesn't matter much from a Cosmological perspective... we possibly are just atmospheric phenomena, and by WE I mean not just little homo sapiens sapiens, but all LIFE on Earth, from the smallest virus tobthe tallest sequoia. Because we never stopped being form by the dame molecules, our feagile lifes at the mercy of a more grandiosedance of celestial bodies. But we? Atmospheric phenomena, like wirlwinds on top of a sea, or bubbles of oxygen instantly created and dissolved by the mixing of water and air when waves hit the rocks. Like the storms of Neptune that can speed up particles of methane, water and helium up to 2000 km/h creating the big blue storm, thanks to the action of superhigh temperatures coming from within its core.
Anton dropped a new video... Time for a break from gardening to have a science lesson... 😁
Gardening is for women. That's why you want to know it, to talk to beautiful capable women.
Anton dropped a new video... Time for a break from going to sleep to have a science lesson... 😁
I actually folded towels!😄
Best comment on TH-cam. I donate fluids to science.
Or from cooking (my case). 😊
As my old pappy would say "it's only exciting if there's a disco there!"
Well-spoken as always.
Thanks, Anton! 😊
Planet Jensen? WooHoo! A home for us at last. But "eight Earth-mass lava world" does present challenges.
Thanks Anton, another super cool video & a lovely way to end a nice weekend. I'm still staying WONDERFUL and still WAVING. Have a great week everyone. PEACE AND LOVE TO EVERYONE ❤❤.
I also wave back every time and am delighted. Thank you very much for the good wishes and I wish the same for you and everyone!

Very exciting to learn more about solar systems
Thank you Anton. You always make my day 🙂
Thank you Anton, always great topics, always put together thoughtfully.
Great video Anton. Thanks as always!
So happy that it’s not just speculation. . maybe educated speculation but some degree of evidence of an atmosphere surrounding an exoplanet. I always assumed it wasn’t unusual but nice to see this. Amazing!
Wonderful as always Anton. Thank you. ☺️
Anton is King of public education! Long live the King 🤴
Love these thought provoking videos, and the fact that you indicated that some of the background visuals are simulations, and the data that is used by the scientists to make sense of the observations. This is very important when talking about what the JWT can "see"!!!
I offer two scenarios. First: The planet is larger than earth so I consider it possible that the core takes longer to solidify. Basically, the magnetosphere lifespan could have a exponential or even logarithmic relationship to planet radius or diameter.
One more possibility is that gas is being literally baked out of the rock due to sufficient energy, replenishing the gas lost to outer space. In such a scenario, the thickness and overall pressure of the atmosphere at surface level is the balance between the gas lost to outer space due to solar radiation and proximity to the star, versus the replenishment of the gas from the intense energy causing said gas to be released from rock. There have been some studies about humans potentially extracting oxygen from rocks on the moon or Mars, but it requires extreme amounts of energy. Basically something a Fusion enabled society might do. So it makes sense if a “hell planet” close to a star does this.
I'm wondering if this planet would look like it has a big tail like a comet. Would be quite a sight to see up close.
Wonderful news from a wonderful person.
Pound for pound one of the best TH-cam channels out there. I have a 3D printed, life sized Anton doll with a wonderful person shirt. I talk to Anton every day “hello wonderful person, how are you?” it always makes me smile.
Bro don't talk about pounding and life size dolls in the same sentence 😭😭
Ok, owning that Anton doll is a little creepy.... Can you make me one? Ta.
Omg i cant tell if this adorable or a Massive over share...
Did you get that 3d print (scan) from an airport body scanner? asking for a friend
Is it ‘fully functional’?
Um… restraining order?
The way the sun ended right above your head at the end of the video.....
Just PERFECTLY WONDERFUL 😌
Thank you, Anton.
Great video, Anton...👍
Thanks for sharing 😀👍
Great Content. So thankful for JWST.
Seguo da anni il suo canale con meravigliosi e interessantissimi video grazie per il suo meticoloso lavoro e le auguro buon lavoro per altri video di grande interesse. ❤❤ Un amico e affezionato dall Italia
Anton, Thank you for mentioning Zooniverse a few episodes ago. We definitely got a good boost in volunteers across all projects. We powered through our last TESS dataset. Could we maybe get a video just covering all the methods of citizen science so more people can participate. Not enough people are advertising it.
Awesome video! This is a really exciting step for exoplanet science. We are just beginning to see the capabilities of JWST. We are hoping to observe many more rocky planets, including those that are more Earth-like in nature.
There could still be multicellular life on a hot planet-life that floats at survivable temperatures if the atmospheric gasses and mineral particulates can facilitate an ecosystem.
Im glad i came back to these videos
Some of the next generation space & terrestrial telescopes on the way in the next decade or two are insane & the techniques studying data are just getting better all the time but need the funding.
Really fascinating times in the world of astronomy.
Great post as always Anton, keeping us updated on these amazing discoveries in the world of science
When disclosure happens and we learn NHI have been here for thousands of years, a lot of people are going to be in shock.
We are amassing new data very quickly, compared to any time in our history, communicating and sharing that data around the planet in minutes, and using machine intelligence to analyze it.
Will we ever again plateau and stagnate as some civilizations have done? Barring worldwide catastrophe, of course.
We are honing our ability to detect, observe and measure at greater and greater distances from earth!
Thanks for sharing this, Anton.
Which civilizations stagnated? And i mean genuinely stagnated, not was declared as such by poets and politicians of their time.
Interesting to know this,thanks 👍😊
I wish we could travel as far as we can see. Thank you Anton, stay wonderful
Honestly I'm still super skeptical about any exoplanet discoveries. Maybe bc I'm illiterate when it comes to the technology they use, but I legit can't even fathom how they would ever accurately measure something that far away and that tiny. (In terms of arc size).
We can't even find Planet 9 but they expect us to believe they know the atmospheric contents and surface temps for planets that are allegedly, at most, a couple sizes larger than Jupiter. In the cosmic scheme of things, a planet is so small to begin with. I would think that even with the best telescopes, one would appear to us, from such a distance, as a single pixel of information, at the absolute best. I'm also very skeptical.
These exoplanet readings are taken by light coming directly from the star itself after being filtered through the edge of the planet's atmosphere. It's much easier to do that with all of a star's light available than to essentially blindly search for an object that doesn't emit any of its own light purely by occultation of a star or the extremely tiny amount of reflected starlight from our sun. In the exoplanet case, we know exactly where to look, we just need to wait for the optimal alignment. Any planet 9 search is like looking for a needle in a haystack the size of Texas in the dark.
@@AndyWitmyerIt's almost like it's very hard to see something that barely reflects any light in a dark space.
It's like a dark room. You can't see a moth in the dark yourself, but you will see that it's there when it crosses the line between you and a lightbulb.
@@AndyWitmyer well you just have to take a look at the detailed publications to see how it works. ..
Thanks Anton.
exoplanet video are always apreciated
Take care of Earth, it's all we've got.
It's all we've got *so far.*
The spread of Democracy will rectify this one planet issue.
@hungryowl1559 let's democratically conjure up a breathable atmosphere
😂@@sir_dragonfly7287
In a billion or so years, we won’t even have Earth as it will become uninhabitable.
This is cool. Mathematically and statistically speaking. This should not be surprising though.
That JWST is expanding horizons.
Yeah I’ve been reading about this. Exciting ❤
Oh good this was one of the planets I was excited about.
In the Trappist system, I would expect the atmosphere to contain alcohol and traces of malts and hops.
Thanks
Take care of Earth, it's all we've got
Earth will be just fine. We have seen several mass extinction before us and it kept us going. We might not be okay, but the earth will keep spinning.
Agreed. Thinking Mars is a backup is stupid.
Exactly, plus even if we found a second Earth, that planet would be so far away that it’s a pointless find. We need to stop trying to find a planet to escape to because we can’t get there anyway, it’s really overestimating our spacefaring capabilities. As of now, we can barely colonize outside our planet properly let alone go 30,000 light years to a random planet with life. Also how likely would it be that a civilization is on that planet with life? Probably not that likely.
@@metatechnologist especially with how hard it would actually be to colonize, there’s a lot more to space colonization than what many seem to think. It’s obviously not like colonizing the Americas or Africa.
@@jonathanhughes8679 I think that may have been implied by: "it's all we've got."
Anton you are the Man !!!
Yup you better believe it.
All facts!!!
Anton, love, u spelled major maior in ur popup suggestion ❤
Great day to be alive. First heard of 55 cancri in 2002 and the earth like planet they expected to be there
While my parents called me into the living room to watch one of the Apollo launches; they didn't do the same when they landed on the moon. I grew up watching the amazing footage of the Pioneer Mission, followed by Voyager, Skylab, and the development of the shuttle which occured while I was in High School in the early 80's. I became a major science and Science Fiction fan hrowing up; and experienced the switch from analog electronics, to digital electronics. I atill remember the hand held elwctric games of my childhood; that used light emitting diodes, then the ones with simple liquic crystal displays.
Seeing what has occured in what is hopefully just the first half of my life; I can only imagine where space wxploration, science, amd technology will be in the next 25, 50, or 100 years.
From what I see abundant and low cost wnergy is just around the corner; and that will change the gave of aociety. I keep seeing progress with fusion twchnology; which will someday power our space ahips, space stations, and space collonies. If I live to see the future technologies and maned space colonies seen in the scifi series The Expanse; I will die a happy man.
Here is what Google says. "But exoplanets, which orbit distant stars, are more difficult to directly observe, because they are much farther away and close to their extremely bright stars. Instead, astronomers often detect exoplanets indirectly, through the effect they have on their host star."
often
Entirely pointless comment, but thanks for helping Anton in the algorithm despite that
No.Anton said we could detect the exoplanet through dips in the star’s light with our backyard telescopes. Not true.
@@paulbyrne2893 that's the transmit method with which, if you had a big enough telescope, you could. You really don't understand any of this do you?
@@jameshall1300 ANTON IS A LIAR
Very much appreciated...I'm learning again
Why in the world isn’t your channel at 13 Millions subscribers already😡 where the hell is everybody
Agreed! Not enough T&A for smooth brains 😂
people headed on their own rocket ships to stupidland these days, expect it to shrink tbh.
I would love a report on damage done to JWST so far. We heard of one major event so far never early on but nothing sense then. I am curious to know if the open face design should be used again in the future, or maybe just that location might be the issue.
Still no news on looking for atmospheres around the Glise system of planets where some are in the habitable zone of their star. Atmospheres on hot jupiters with 1000 - 2000 degree Celsius temps doesnt seem likely for life to me ...
These types are probably easier to get clear readings on since they're larger planets. I'd imagine there's probably timing issues involved as well, since you'd need a transit to take a reading in the first place.
Will you please do a video about the solar storms.
Yay more preliminary work.
It seems that every week the JWT discovers something interesting, can’t wait for something totally mind blowing for us on earth
Unfortunately I cant found the link to the comsmic call or matti. Is it accidentally not included in the description this time or am I just mistaken? Thank you very much for your great work Anton!
If someone could attach the name of the video, it would be great. Unfortunately, I couldn't find it via the YT search with the search words either. Thank you.
I won't hold my breath in anticipation.
you should really only do that for submersion, it's not super healthy.
Awesome 😄
Thanks for providing a facts based source for space news. There’s so much garbage out there. This show is refreshing.
Amazing.
Loved it
Cab you have an episode on the magnetic pole movement and how long before it flips?
Basic meteorology is usable here: A hyper extreme low pressure area with a hyper extreme high pressure area. The efficient distribution of heat from winds traveling faster than the speed of sound.
I'd expect a boat load of sulfur compounds bubbling up from the magma. Most likely, volatiles trapped in the mantle are bubbling out gradually over time. This, along with the temperature difference, should increase the convection in the mantle greatly compared to Earth, which would help delay the loss of all the volatiles through getting baked out.
So, I guess my prediction (which can't be tested without going there and digging in the mantle, but is _technically_ testable?), is that the night side has more volatiles trapped in the mantle than the day side, but much less than we'd expect in the absence of super convection stirring things up.
Does anyone know the name of the music at the end of Anton's videos? If you do could you pass it along? Thanks.
Anton is the chosen one.
How is this even possible? I thought the only way to discover planets around a star (even the closest star) was to detect the brightness dim. So I don’t really believe if that’s the case that you can detect anything else about the plant, I would even question that you know for sure that the dimming of a star can confirm that it’s a planet!
There's multiple ways. Transit method ( dimming ) and radial velocity ( the wobble of the star due to the gravity from the planet ) are the two I've heard the most about. For these readings, they take multiple spectrograph readings from the star when the planet passes in front, and using a baseline from the star itself, you can see what is missing from the spectrograph reading when the light passes near the planet. Those missing spectra are what are used. It's no different than doing transmission spectroscopy on earth, just on a much much larger scale. We've been taking spectra of stars for well over a century now.
Why won't you talk about the recent extreme geomagnetic storm we had, the danger and the beauty of norther lights? Its the strongest since 2003
Such exciting news! These are the technologies and techniques that could find an Earth-like world.
Love to know if there's a way to detect liquid water. That would be a great sign for finding life.
I first read “JWST finds EXTINCT atmosphere..” after learning yesterday that one of the ways its looking for alien life is by sign of them having already destroyed their planet and went like “WHAAAT!?”
It is beyond astonishing that scientists are now able to measure details about planets so far away - even more so considering that we only recently confirmed the existence of such planets outside our own solar system in the first place. Fascinating times
Nice
They said Webb is revolutionizing astronomy, but everything is so slow: we are talking about Trappist star system again and again, find new systems already!
I can safely theorize that any planet with liquid water in a habitable zone would support some sort of life ! There are probably billions of planets out there !
Extremely doubtful, imo
We know so much, yet so little.
no, we know enough to know how little we know, it being a lot is just how limited our capacity is in relation to the information, not the amount of information we know, nearly nothing.
Constant edit cuts remind me of Max Headroom in the 80's
Earth, circa 2090:
"Sir! Sir! We have received a reply to the message our great grandparents sent to 55 Cancri e!"
"Well, has it been translated?"
"Yes, Sir! We've just completed the task!"
"Well, spit it out! What does it say??"
"OK, let's see here...'OW'...another 'OW'...then 'OUCH MY FEET ARE BLISTERING'...and finally...'HURRY, SEND AIRCON'...and that's it, Sir!"
"Astonishing! Quickly! We must let the Earth Council know! Tell them that we have decoded the 'OW' signal!"
9:30 atmospheres can last long, can be created by various planets and can contain volatiles
Have we found any planets in orbits that don't cross between us and the star? Considering the number of "nearby" planets, it seems that there must some of every imaginable configuration even in this one galaxy.
Hello Anton, can you explain how we are so sure this information prove what they say?
So… its so hot we wouldn’t last a minute. Welp, it’s still nice to discover planets with atmospheres and volatiles and what not.
It seems like there is always something new to learn about Uranus

I just want to live ling enough for them to discover life in other planets
I wonder would it be a waste to get the jwts to look out towards voyager 2, it would be a great picture beside the pale blue dot
Planet f in this system is very interesting. 55 Cancri A star is slightly smaller and less luminous than the Sun, and Planet f is in an orbital distance almost the same as Venus. This puts it within 55 Cancri A's habitable zone. It's a sub-Saturn-mass planet, and could host a large moon stably. This moon would be able to host liquid water, and since it would be orbiting the parent planet likely in several days to a week or two, it would be protected from tidal locking relative to the star, and have a day-night cycle. Interestingly, it would also have a situation where one side of the moon could experience a 'double day', since the side facing the planet would be eclipsed by the large planet every orbit if it's in a planar orbit with the star. This might result in a more habitable side of the moon, especially if the orbit is on the slower side, since when that side faces the star, it experiences a second 'night' of the eclipse that will let it cool off again. That side of the moon is also further away from the star when it is facing the star, and thus will not heat up as much.
The outward-facing side of the moon, however, will have much more extreme temperature swings. It faces the star when the moon is closest to the star, and away from the star when the moon is at its farthest. Given the dramatic differences in temperature variations between the two sides of the moon over the period of a typical Jovian moon's orbital period, I would expect it would host powerful winds and raging storm systems if it has a significant atmosphere.
