It's weird to be at an age where I hear a future date and realise that I may not be alive at that time. I really want to know what those future telescopess find!

1:04 the most logical answer to the Fermi paradox I’ve ever heard.

One of my favorite Si-Fi movies is 'Contact'. A major milestone toward our search for extraterrestrial will be when we can actually image exo-planets. I hope I'm still around for that and the first human landing on Mars. I was very excited to witness our first lunar landing on July 20, 1969 just after graduating H.S. and now I'll be able to see our return next year.

I'm glad they pointed out some of the difficulties and possibilities of false signals and uncertainties.

I refuse to believe that we are alone in the Universe, just that life might be a bit rare, like maybe on 1 planet in a billion, in galactic scale, that's relatively rare, in Universal scale, it would be common, but of course we don't know. The question is then, will we ever discover alien life? Maybe, but if we could be so lucky to find life or traces of life or building blocks of life on just some of the moons in our own Solar System, it would be THE NR.1 GREATEST scientific discovery ever.

I'm going to be very upset if we don't discover alien life in my lifetime. It is the one thing I am most curious about.

"More than five thousands planets" Wow! This is a lot! I remember the first one(s). "In the last three decades" Wait... I resent that that one. 🤨

The thing with studying atmospheres is the best we can get is "highly probable". Only "intelligent" life could send signals or show signs of life "beyond any doubts" and those have abysmal odds. Even at that scale. Still. Exciting stuff! Keep on going researchers.

Let's hope we don't destroy ourselves before we can get to those distant worlds.

What I would love to see is observatories built on the dark side of the Moon and networked together.

Telescopes are our starships. We may not ever be able to travel the stars like in sci-fi, but we can do so much with telescopes thankfully. I really wish we would prioritize many more telescopes and get the luvoir up before 2040!

Hey Hank, i know you love learning. You can say Chile like the chileans if you read it backwards "Elihc" then keep that "E" sound (phonem) for Chil"E" instead of Chil(ee, ɪ). Hope you like it, if you do, try it for the next video!!

I had my eyes closed and heard you talk about the “Play Doh” telescope. I think I should probably lay down for a while.

Great video, Hank, but I'd say that the greatest moment in human history will come when we stop destroying the only habitable planet we know. If we ever have a convo with aliens I'm sure they'll ask why are we not taking care of our green jewel. We don't even have an answer for that.

We're going to have a VERY hard time if we end up discovering (or getting discovered) by a form of life that does not have one single solitary thing in common with ANY of the lifeforms on this planet. We'd have literally no idea what we were looking for

It's life Jim, but not as we know it not as we know it, not as we know it It's life Jim, but not as we know it not as we know it, Captain

If we find a planet with a heavily polluted atmosphere, does it count as harboring an intelligent species?

Forget space. We should be trying to find intelligent life here.

The future of search of life AS WE KNOW IT FROM EARTH would be the correct title

If there is any life on another planet, one thing is for sure. They will all start as simple single cell organism. How ever what they will evolve into is where things get complicated. Just the probability that one single cell organism will engulf another to form a complex organism with a nucleus is extremely low, and even for those to grow into multicellular is even lower than that. Everything from the amount of energy from their star to the gases in the atmosphere to the geography of the surface of the planet will make a huge difference as to where their evolution will take them.

There could actually be alien life all around us but if they're light has to travel a thousand light-years to get to us we wouldn't see it

1:45 , I understood that Stargate atlantis reference.

I really hope we can set up some sort of system to use our sun to create an Einstein ring. Like... Please do this before I die. I want to see alien worlds in detail. I want to experience that moment when we conclusively prove we aren't alone.

thank you

Go Go Sci Show!

As soon as those NIMBYists realize that the TMT isn't a "colonial" project, but rather something that generates knowledge that will benefit everyone (and grant prestige to the locals), the sooner the TMT can be built and fulfill its role in the search for life in the universe.

The calendar looks great 👍

Thanks 👍

Thumbnail: "Could this find life?" My first thought: "Maybe. Let's get a bird up there and see."

Fantastic

This is so awesome!

Can we find planets, or detect possible life on planets, whose orbital axis goes through us? Such planets don't block their star, nor does the starlight get doppled.

Of course we have to look for life as we know it. How would we even recognise life as we *don't* know it?

After discovering alien life, we do what? Anything. Because those worlds are so many quadrillions km away, it's impossible to say a signal meaning HI and wait the response who will take more than a lifetime.

Now someone come up with a propulsion system that can obtain light speed yet carry life.

Hank, I can’t tell how excited/concerned you are without you grabbing your hair. Please carry that over.

Perhaps it would be easier/cheaper to first rule out planets that probably do not have life, then plan expeditions to the other planets. Or, we could focus our attention on biosignatures that probably indicate life, even if there are known life forms that do not emit such biosignatures. Then we could try to study the life on those planets and thereby gain additional insights as to biological life in general, which could be used to inform our search for life elsewhere.

Recap by Tammy AI

WHERE IS CAITLIN HOFFMIESTER ???? what have you done with her ?

So wouldn't plants on a planet orbiting a start producing different strengths and frequencies in the electromagnetic spectrum than our own star, act differently. Would they still be identifiable the same way?

it can find life if you stand in front of it

Esperare con mucho gusto! Love from México baby

I wouldn't get to excited. If we by some miracle find what we think may be intelligent life several thousand or million light years away we'll never meet them. Would take hundreds of thousands of years to travel there

please tell me you said "more than a puddle jump away" as a stargate reference =P

Cool.

Imagine, 50 or 100 years from now if we discover that there is alien life out there somewhere (or at least all signs point to that conclusion), so much industry would be completely rerouted to reaching or at the very least contacting. It could mean a complete redirection of our species' goals.

It is good that all this effort is being put towards searching for et life. For eventually man will get weary of searching, and finally come to the realization that it is not Intersteller, it is Intrasteller! Though scientists will continue to stick their heads in the sand, and like a religion, believe that there is a Star Trek universe. Or, maybe begin to awaken to this greater being dwelling within us, residing in a dimensionally greater universe within consciousness, where all the alien life is to be found. This world and universe is not your true home.This is a schoolhouse for image making. So I present to you now Neville Goddard's hypothesis, where Earth is a LIFEBUBBLE. According to Neville, life is the sole activity of Imagination, who is an actual being, dwelling in a dimensionally greater universe within consciousness, and is presently dreaming your life. And since life is the sole activity of imagining, you aren't going to find life outside of the Lifebubble, no matter how many space probes are launched, to go and seek for it. Questions for mainstream science to first ask, before spending billions on constructing an et life-seeking space probe: *What is life? *How does it arise from inanimate matter? *Does life always come from previous life, and unbroken thread? *Could consciousness and life ever be separated? The answer is quite shocking, though it explains everything going on around you. Imagination is meditating your life into existence. Think DOCTOR WHO, and his phone booth. Step into the phone booth, and now you're in a vastly greater room, which defies the laws of physics! There are worlds within worlds, and you are heir to all of them. Neville Because of childhood brainwashing with media propaganda and movies, even top scientists jump to the conclusion, that there just HAS to be life in outer space. We have been indoctrinated to believe in e.t. aliens since childhood. It has become a type of religion. Then it is reinforced by endless science fiction shows, and CGI effects. Though so far, aliens only exist in the minds of imaginative and artistic humans, who are continually casting forth their CGI enchantments. For life is a very rare thing in the cosmos, as in nonexistent? Why does Neville say that? Because you are the light and life of the world. As in a dream, so too here. You are its operant power, it doesn't work itself. The Earth could be the only place in the universe that could cradle this life experiment. Why? Because all of life begins and ends in you. Imagination is awakening from a long sleep. A planet having the right 'building blocks' for life, orbiting in the Goldilocks zone, does not automatically mean that life will arise. Just look at what we've discovered so far. There are unnumbered examples of planets being in the 'Goldilocks Zone' around their respective star. Though, none have been found to have the right planetary configuration to support life, when compared to our solar system. For instance, Jupiter and the gas giants, continually sweep the area clean, taking the asteroid hits for us, and have precision orbits to do so. Any farther away, and life would be snuffed out. Any closer, and their gravitational pull would tear us apart. The Moon is also precision in its size and orbital distance. It, and all of the planets are supportive in protecting life here, though still are dead as dead can be. Could it be true that our universe is just be-bopping along to the laws of physics, and is too poor to produce even one seed on its own? 🙏🧞🐛🦋 en.m.wikipedia.org/wiki/Rare_Earth_hypothesis

I was expecting a mention of the Carl Sagan observatory.

When I watch videos on finding alien life, I get the feeling we're assuming aliens out there (may they exist :)) don't have any technologies to shield themselves from us. Next question: what would it take for the scientific community to accept a signal as evidence of conscious alien life? I feel like we, as humans, lack a little self-reflecting on whether these aliens really want to show themselves to us in plain light

Based on previous data- Aliens will be crabs.

Spank the Hank~

Basically it's detecting alien farts

1) winter/summer flips due to tilt, so only if there is a tilt to the planet. 2) we are virtually alone, we couldn’t communicate with anyone unless they come here and share information, do we really want that? Especially since we are only 100k years old with a beautiful almost virgin planet

LITERALLY WAS JUST LOOKING FOR THIS YESSS

Hopefully the alien dolphins discovered radio and give af about what we have to say

Our first thought on alien contact: how do they taste? When it turns out they're very hostile, they'll be asking how do humans taste.

Cool video!

are there any infrared pictures of earth? id like to see infrared plants.

Farnsworth's smell-o-scope is the only way forward

What kind of gas signature does earth have? Since most of the atmosphere is nitrogen.

Of course the video is made before JWST confirmed it's first exoplanet (and an earth-sized one at that).

Very interesting... But where in the video was the observatory from the thumbnail? Did I just get click baited by scishow?? What is that building??? What is the answer to the question in the thumbnail regarding said building!?!?!? I must knooow!!!

Is there really temporal changes due to seasonality on Earth, after all, it is simultaneously summer and winter in opposite hemispheres. Does this not cancel out the effect overall?

As Stanton Friedman said,"SETI: Silly Effort To Investigate"

Can we confirm if a planet is tidal lock or the axial tilt?

Any life we find will only be non intelligent life.

Hwo can you detect seasons on the planet if youre only able to see it when he goes in front of the sun? wouldnt be always the same season detected?

Do we use this method on our planet for base statistics?

When we went to the moon “we might find life or origin” When we send probe to mars “we might find life” When we launched Hubble “highly chance to find life” When we have seti “we might just get signals of aliens” Launched jwst “sure find life just a matter or time” Now this? Take a rest. We will never find life. Too vast and huge to even put throw a dart and land on one with life if it were to make into a huge map

The thumbnail shows a picture of the future thirty meter telescope captioned with "could *this* find life?" but the telescope is never mentioned in the video. the giant magellan telescope is mentioned for all of one second and the video is focused on entirely different classes of instruments. Not what I was expecting.

My guess when it comes to the search for extraterrestrial life, it is my guess that it'll be never. I suspect we are alone in the galaxy or mostly alone. I think we'll find a few probable signals, but nothing definitive.

he said fun-"j"-i and we cant let hat stand

The discovery of extra terrestrial life would never be “the most important discovery in all of human history.” Steel is the most important discovery in all of human history.

I hope we don't use ourselves as an example of intelligence life

Sadly if we cant communicate with each other i very much doubt we will understand anything alien, even if its broadcast right at us

What happened with the Sagan space telescope?

its also crazy to think that infrared light is so healing to humans as well.

The way Hank says "fun-dji" makes me want to hold him hostage, tied to a chair, exposed to the summer heat and winter freeze, until he begs for forgiveness and swears he'll start saying it correctly.

Have we, as a species, come up with an international agreement on what to do like, when we actually find life? Or when life finds us?

Earth scientists don't know what is in the Amazon rainforest nor the bottom of the Ocean. Looking for life on another planet, don't hold your breath.

If it could, they wouldn’t tell us cattle.

I predict that within the next 100 years we will confirm life on other planets... as to whether there will be life on ours is still up for debate...

For anyone really interested in the critical thinking that goes into the search for ET i HIGHLY recommend checking out John Michael Godier’s channel on KZfaq. Mind blowing though processes on every aspect of space, time, and alien life

perhaps we are putting so much emphasis on space observation and exploration being about finding alien life that we are essentially damaging the field and setting ourselves up for disappointment. The more megaprojects (like kepler) fail to yield results, the less public interest will be in space as a whole...

My friend just bought one of those things A(the thumbnail) it’s an automatic kitty litter cleaner 😂😂😂

One of the problems is that what we're seeing is what was not what is.

Betteridge's law of headlines is an adage that states: "Any headline that ends in a question mark can be answered by the word no."

If one day we detect city lights on a planet through a telescope, that's definitive proof that there's life. Without needing to even see the beings or inhabitants of the planet.

Seasonal variations are a pretty weak idea. Most planets don't even have seasons because they rotate in the same plane as their orbit. We have no idea whether there is any correlation, positive or negative, between life and seasonality. Raising and lowering the temperature on an intermediate-term basis can change the equilibria of all kinds of chemical species, change states, etc., so seasonal atmospheric change shouldn't be at all uncommon, life or no. Bad idea, cut their funding.

i find the frequency of "encounters" or such "coincidences" go up (increasingly) exponentially instead of linearly/constant hypothically via a wave-system medium (somewhat-to-often analogous to water for ocean waves). Specifically of which, proportional to e^x inclusively.

how weird would it be to discover an exact mirror of us, at the same point in their timeline, technology, even ourselves?

When will we hear intelligent alien life radio signals? As soon as we build a radio telescope on the far side of the moon. The moon will insulate the telescope from all but space probe radio signals from Earth. The allocated bands for radio astronomy in the US allocations is dismally tiny, less than 1% of what's used. The atmosphere is also really good at reflecting & absorbing of radio frequencies. On the moon, there is no limit to what signals can be heard because no atmospheric resistor gets in the way. Of course, other science can be done with this radio telescope, but we'll pick up what's there, all of it.

"...a puddle jump away" Are you referencing Stargate Atlantis?

Look up the canceled NASA Terrestrial Planet Finder and its follow on. We'd be a lot further in SETI and Exoplanet discovery if it had not been canceled.

Don’t hold your breath waiting for extraterrestrial life to be found, particularly of the intelligent variety. The chances are likely to be ludicrously small, given the extraordinary improbability of our existence. Where are all the aliens? We may be it! At least in this galaxy.

Can we smart people collectively decide to live somewhere together?

ashtronomers

GRBs all arrive here in order of wavelength. They don't like saying it that way, because Einstein is a time lord. Relativity only works AFTER you use transform equations to CHANGE the numbers to make it work. This leaves a non-transformed reality behind. It DID NOT DISAPPEAR just because you transformed everything and got the answer you were looking for. Pretend Relativity is wrong, and light waves from GRBs produce slower long waves and faster short waves. A longitudinal scrambling in the alien signals would be ignored by us for over 100 years. Testing your analogous theory is not the same as questioning it.

Finding aliens would be catastrophic. We can't even live peacefully with one another.

The universe is a very lonely place.
