SETI Institute Panelists:
Nathalie Cabrol, Director of the Carl Sagan Center
Seth Shostak, Senior Astronomer
Mark Showalter, Senior Research Scientist
Fergal Mullaly, Senior Research Scientist
Hosted by Bill Diamond, President and CEO of the SETI Institute
Is this the generation that will discover extraterrestrial life? Some scientists have opined that we’ll find other living beings - whether they be microbes on other planets or intelligent beings in another star system - within two decades. An energetic panel of SETI Institute astrobiologists will discuss why both science and technology give support to the idea that we may soon prove that Earth is not the only world where life has arisen. Audience Q&A follows panelists.
Join us for a special tribute to Bill Borucki at noon as we kick off the panel discussion.

Yes, the intro was interminably long, but drop in at 9 minutes or so and you'll find a great talk. Informative and entertaining.
Seth Shostak is always very interesting and entertaining, and 100% worth listening to.
9:35 is way too long of a introduction. But when they finally got on with the show, it was very interesting.
Thanks for saving me 9 minutes.
Whatever happens, I just hope we find out either answer, there is or there isn't life beyond Earth, within Seth Shostak's lifetime lol because he's been funded to search, and nobody has been looking with more enthusiasm than him.
If anyone deserves to know for sure, it's Seth Shostak. 👍
TWSTF 8 see ‘To the Stars Academy’ it’s being briefed out now.
In response to Mark Showalter and eukaryotes, I've found out that many of the one-celled ones like to eat bacteria. So some protoeukaryote could simply have eaten the alpha-proteobacterium that became the ancestor of the mitochondria. As to why it took so long, it was because this endosymbiosis happened not long after the Great Oxygenation Event, and it was that event's free oxygen that made mitochondria useful.
As to sexual reproduction, that apparently goes back to the ancestral eukaryote. It had a cycle of haploid - cell fusion - diploid - meiosis - haploid again. If many protists and fungi are any guide, then it would reproduce asexually most of the time.
The simple answer is we will find life beyond earth when we find it and not a moment before. A better topic is what should we be doing to prepare for the day we find that life? If it is more advanced we shouldn't we be concerned about what they will think of us? We should put our best face forward and 1) stop killing each other, 2) practice communicating with non-human life forms on earth like dolphins and whales, 3) if we fail at communicating we should develop advanced weaponry for self-protection in case ET is hostile, 4) increase the number of people in space so we won't have all our human eggs in one basket, 5) promote the creative arts to add beauty to the universe, 6) treat each other with kindness and respect, 7) promote alternative energy like solar, wind, geo-thermal, etc so we can show ET we can live in harmony with our own world and therefore we can live in harmony with them, 8) let our political leaders know these are our priorities that we want them to achieve or we will vote them out of office, 9) get organized to do all of the above and more. Our radio, television and radar waves have traveled over a hundred light years into deep space passing over 7 thousand star systems. Some of them may have planets with advanced life and some of them may already be on their way to meet us.
a wonderful talk, especially the Q&A
Great discussion. Hope to see more videos like these.
The answer to the Fermi Paradeox. There is a beautiful loving Universe many people claim they experience when they are undergoing an NDE. Long before any Advanced Civilization gains the technology necessary for Interstellar Travel - they find a way to escape to that Universe. In other words, it is technologically easier to escape to that other very pleasant and safer place, than it is to develop the Type II Civilization Technology necessary for Interstellar Travel. This explains why we have found no sign of an Advanced Alien Civilization anywhere in our Universe.
They either find the more pleasant place, or they create it for themselves. Perhaps. It's possible. Or they annihilate themselves. Also possible. Let's hope it's the former. :)
Anton Petrov did a video where he introduced a new variable in the Drake equation.
Apparently star systems need sulphur to have a chance a star system evolving life as we know it and this happens only when super massive stars explode. This happens rarely (cannot remember the %) so the odds of finding life is greatly diminished.
"Life as we know it" could be an extremely limited understanding, though. If we were deep sea fish, we might assume that all forms of life must live under water, as that would be the only life we had observed so far.
Really long into. Skip to 16:01 to avoid housekeeping and go straight to panel.
Yeah, I'm not even kidding. It's that long!
thank you lol
+Gordo Simmins Cheers bro!
+Gordo Simmins thanks bro
9:34 you don't want to miss anything from Seth Shostak, do you?
The real MVP
The dome joke was funny...wasn't expecting that :)
About tardigrades, they can survive a lot when they are dried out, but they are not indestructible. They are also among the closest relatives of arthropods, though they diverged around the base of the Cambrian. Tardigrades are not alone -- some bacteria produce spores that can also survive extreme conditions. My favorite tough organism is the bacterium Deinococcus radiodurans, the ray-enduring fearsome berry. It can survive doses of ionizing radiation well above our lethal level -- but it does so by using its adaptations to surviving dryness. It does not make spores, so it does that surviving while in an active state.
Seth is entertaining as always, nice analogy with Cicero! :-)
So now l know why China is building such a big one.
I'm curious how Shostak feel's about the recent UAP revelations from the Pentagon?
David Hannum,
Great point.
Me too.
With best wishes.
I wonder, if we could discover life inside comets and as far out as the Oort cloud, could we then extend our search for extra-solar system life in the Oort clouds (if they exist) around other stars? Would the Oort clouds of other star systems be easier to detect than the actual moons and planets? If signs of life could be found there, it would strongly indicate that there might be life on some of the moons and planets of that star system.
For the first 3 panelists the answer is a question of technology, so 20 years, 35 years, no number: just whenever we return samples. The final panelist looked at the history of life on Earth and, based on how long it took to develop intelligence here, maybe never. The middle two only talked about microbes.
This was a very interesting panel
An important and informative panel. Introduction was way too long. Who the heck is doing the audio?
I would like to see Travis Walton on the stage and give his perspective as well....
I used to feel sorry for Travis Walton because I think he was exploited and bullied into going along with the abduction story, but not anymore. He's in on it and it's his primary income. He might even believe his own story, but it's not true. It never happened.
I Always like to hear Seth talk, athough I dont share faith the government or that they arent capable of keeping big secrets. On this pannel I also really liked Mark, especially him adressing we look to explain a lot of things by looking through a (cultural) mirror, its a serious problem and causes tunnel vision. Something we also see with historians and archaeology when it comes to the ancient/pre flood world.
Many ancient civilizations have recorded visitations by gods from outer space. Some were hostile and some shared their knowledge. The Sumerian clay tablets describe how these mortal gods lived among them and instructed them in the ways of agriculture, building and the domestication of animals.
Gods from the heavens. Not aliens.
Hmm. You'd think that a discussion hosted by a technology company would have better sound.
It's bloody hopeless! Nathalie Cabrol is about 24dB louder than everyone else, constantly having to ride the volume.
What did Microsoft ever do for us?
Signed, the Peoples United Front of Judea.
Well good talk!
Would be very interesting to be a habitable planet of a triple star system. The three stars wouldn’t be the same, one could be yellow, one could be blue, one could be red.
I think we can make a very big telescope like that. In the past we launched many units to build the ISS (INTERNATIONAL SPACE STATION). Now, let's launch a lot of units, only this time they will make up a big telescope that can expand our horizons. We will be able to detect planetary atmospheres as well as use the direct photography method. Finally, I would like to add that I estimate that this giant telescope will have a mirror of 32.4 meters.
the delay between audio and video is ridiculous.
Build the dome!
Seth Shostak is super quirky.
Smart but super annoying. Cant stand him
23:05 LMFAO!!!
Audio is not equalized
Could it be we're searching in a totally wrong way and that ET's are sending signals on the quantum level?
;) MAPS is doing very interesting science too =)
Love Seth's enthusiasm and humor.
Update: please see ‘Marco Rubio report’ coming out on or after 1st June 2021from Senate intelligence committee could show that we are being visited already.....who’d thought it! 😄
Except it didn’t.
@@Living_Matrix1 yep fair point. But stick around…it’s not over until the fat lady sings. More coming down the pipeline me thinks!🧐
@@Living_Matrix12 weeks ago it appears some members of Congress were briefed that there have been back engineering projects of recovered material. Dr. Gary Nolan of Stanford University has confirmed this. Interesting times indeed.
Sir, the public understands the continuous acceleration of scientific experimentation speed FAR better than you claim. We need MANNED Missions out to Mars and beyond, too...not mere DREAMS about such. I personally believe that our current dataset from ISS, etc.is just about good enough vis-a-vis space travel impact on human beings right now, too.
That guys laugh though XD
He said "Without further ado..." right before providing another 5 to 10 minutes of ado. *facepalm*
He did NOT provide ANY "ado". You're an ignorant moron who doesn't know what "ado" is. *FACEPALM.*
Matt Smith 😭
@@philsurtees a·do
/əˈdo͞o/
noun
a state of agitation or fuss, especially about something unimportant.
"this is much ado about almost nothing"
synonyms: fuss, trouble, bother, upset, agitation, commotion, stir, hubbub, confusion, excitement, tumult, disturbance, hurly-burly, uproar, flurry, to-do, palaver, rigmarole, brouhaha, furor;
I appreciated Matt's observation, because I agree, there was a lot of fussy-talk following the promise of no more fussy talk, as in the meaning "fuss about the trivial.'
Suppose we decide to Tera form Mars, and before we get there another civilization wants to move there too. Do we claim Mars as being in our territory so we get to keep Mars?
11 minutes seems to be where the discussion starts. Everything before 11 minutes seems to be wasted time on introductions.
how many resources are allocated to this research
Almost nothing, and ~none of it is funded by US taxes.
As much as Russian Oligarchs are willing to spend on it as their pet projects.
The last question was obviously meant as in 2 way interaction, but the guy answering either didnt understand that or ignored that, that leaves you thing about how if a signal was sent and it reached here it may of already be before or after are species dies. There life outside of earth is fiction as far as we know
Intelligent life has already been here from other planets and most like is here. They are looking far in the distance when the answers, the truths are right under our noses....and we have pretty hard evidence of that.
Link - "hard evidence" please
What about The Five hundred meter Aperture Spherical Telescope (FAST)
+FriKuShAxP
The resolution that FAST will provide will not actually be that great, unfortunately. Yes, it has an effective diameter of about 300 m, but at the long wavelengths it will operate at, not such awesome resolution. An optical interferometer will be the best option, but first we will need to prove the concept at far-infrared wavelengths (which is also extremely difficult!).
Fast has diameter of 500 meters.
Oh, jeez sorry, 500 m then. And, as I said, at those wavelengths it will have crap resolution (even with d = 500 m). ALMA has better res. at the long end, and JWST at the short end. I'm not sure what FAST will really add?
Since Fergal moved to California, he has adopted the "the problem is, is that .." error. Why don't people see that it makes no sense?
do introductions really have to take more than 15 mins ?
+Tim V
Surely you exaggerate. It only took 9 minutes and 40 seconds. And we are so much richer for those 9 damn minutes of utter boredom.
+TheDudeKicker
And as I typed that, the introductions started again and I was proven wrong. It did take more than 15 minutes.
The preamble is tedious.
16:00 start
That Kermit voice at 34:35.
Never, Earth is an enclosed system.
Most people will always go for the brown pill. It's nice and easy to swallow.
2019 on Mars !
Biting the dust.
Oh I don’t know.
Add subtitles please
No
Ok, so we spot a backyard BBQ going on at 836,000 light years away on some unknown planet. Now what?
Ask them what's on the menu?
Ah…. How long is piece of string?
Life beyond earth found us, haven't you noticed.
No
@@Living_Matrix1 Imagination is outside the matrix. What matrix? No matrix restricts me!
if we go into the oceans of Europa and find nothing we should just put something in, and look at this a a great opportunity to explore a moon sized lab
however we need to be very careful when we land those missions to Mars and the Jovian moons to not contaminate those places with our kind of micro life which would then ensue in the first planet wide bio-genocide to those poor local microbes...
How can they say that life on earth happened quickly? We're the only planet we know of with life... surely we need a few more planets in other solar systems so we have something to compare our development against?
+Stephen InGermany Earth cooled to a level where life was possible (liquid water could pool) about 500 million years after it formed. It was then impacted by another protoplanet, which again led to a further wait of several hundred million years after it, and the moon reformed and cooled again.
Right after that ... well i say right after , but I mean millions of years... well right after that we find the very first life, just after water as liquid was possible. In other words life formed immediately with the introduction of water. It probably formed before the impact... we don't know, theres nothing left to find out!
"surely we need a few more planets in other solar systems so we have something to compare our development against?"
I'd imagine a few thousand is enough no?
But anyway we'll likely find out on May 10th (this coming Tuesday)
Mickelodian Surname
Why? What happens on tuesday?
Stephen InGermany You mean 6pm GMT today? My guess...and its a guess, is that a habitable world, with a first spectroscopy indicating water, nitrogen and water vapor will be announced in a far-flung (well actually rather local) system 40 light years from Earth. It will require a more detailed look via James Webb when its launched, but enough orbits have now taken place to do a spectroscopy comparison of star compared to star and planet.
Its just a guess, I based it on the available evidence I have. See the home page of the NASA Kepler website.
It might however be as boring as just oxygen found... or it 'might' be as exiting as finding a signature that denotes someone throwing shit into their atmosphere (that's be astounding, but not very likely).
Oxygen however can occur naturally on planets that have titanium in the mantle.
EDIT: facebook.com/NASAsKeplerMission
Then again they might be about to announce the mission is scrubbed completely.... which you wouldn't get away with in Europe, but thats the way americans look on science I suppose.
ProjectsBlack "I don't think we will know if life existed on Earth prior to the impact with Theia."
Can't think of any method you could use to find out either. Might be able to find earth rocks thrown off the planet though...with fossilized microbes, but that's also be pretty unlikely, the solar system is a bloody big place, and rocks are small and fast moving.
Its more likely someone will get one impacted into their face. A close up of early life if you will!
Star Trek Theory Our star is a third generations star...that means that there were many, many more solar systems here before our sun came about. Our sun is in fact rather late to the party.... So assuming life forms quickly, then ours formed rather late. Being late to the party and running up the driveway won't make you arrive on time!
There is probably no life beyond Earth. Definitely not in our solar system. We are alone in this dimensionality.
Watching this 4 years after your comment and a year after disclosure. How small and ignorant you must feel my friend. There’s more life and things out there than our human brains can even comprehend. Which is why some, like you, simply deny it. Easier to just put our heads in the sand and go back to the football game, eh? 🙄🤦🏻♀️
Knocklyon ?
Shostak still thinks he's starring in an 80's Spielberg movie.
they kept saying Biogenesis - I was under the impression that biogenesis was life from life
The word means "start of life." Abiogenesis is kind of superfluous.
21:04 - "These planets are very far away" - Are you sure they're not just small?
LOL good point I just imagined that and laught out loud :)
Are we seeing Uranus or just your anus 😲⁉
When THEY DECIDE!
the flying discs have been here since the 40s after roswell..fact
A fact requires some evidence. Where is your evidence.
Sound level is fucking annoying
You won't ever find life beyond the earth because there isn't any.
MrSerendipity01 yes the probability is far to low
How about getting an Archaeologist to examine the Curiosity images for possible signs of ancient intelligent design - why doesn't SETI do that?
soundofthenebula because you can't do that with pictures. Jesus
Will life see us? Will they care?
they did not SEE us, they MADE us :)
Birds and reptiles come after mammals?
Please skip first 10 minutes.
OMG Seth is getting old. Time is so merciless.
"When will we find life beyond earth?"........... Is the unanswerable question, so why ask it?
It could be like the guy looking for his glasses everywhere, when they are atop his head : what if THEY were already here for some long time and able to stay hidden from us?
Just saying ;)
Some form of life? Could happen soon. There might even be some in our own solar system. Intelligent life? Probably will never happen. It's too rare and the universe is too big both in space and in time.
Depends on how intelligent they are and whether or not they want to be found, doesn't it? We can't put limits on capabilities of beings we know nothing about.
If lunch makes you tired, you ate too much carbohydrates and your body has insulin spike, until you fall ill with diabetes. That's the problem with average meals.
Tnx Neanderthal gene's.
unfortunately very very long introductory material
Where? Subsurface Mars.
Aliens discovered us thousands of years ago. Many of the kings & queens of ancient civilizations were aliens. The first 3 kings of Egypt were aliens. They've lived in vast, worldwide, underground cities to this days. There're at least 57 different, alien civilizations, each with their own, unique language & culture.
Psst. The KIC system. We've already found ET.
ET likes chicken too! I love that flav.... oh, I thought you said KFC.
You're pulling our leg zeb. There's no way you know ET likes chicken. You're being ridiculous!
+Gordo Simmins My niece worked in KFC during her college summer break..... funnily enough two little grey guys in an old VW pulled up one day and ordered a family bucket.... little fuckers love the stuff... Chicken is clearly some sort of universal constant!
+zebonaut smith You are referring to KIC 8462852? I would love to believe that we have discovered a Dyson sphere or some other monumental alien structure, but there simply isn't the data to support this assertion. It's a hell of a leap to go from "Oh, that's odd." to "Aliens!" I'm not mocking you, just suggesting that you dial it back a bit until we have more information.
yeah but speculation is so much fun! anyway Tabby's star is surely going to get some special attention from the JWST as soon as possible.
ProjectsBlack "Well 100's of thousands of people go missing around the world each year. "
Meh I think those folks ran foul of the other people on the planet, not aliens wearing napkins and holding out a plate..... a shallow grave rather than a telescope is our best bet for finding them
‘To the stars academy ‘ renders all this redundant. Oh dear.
GET BACK TO WORK, I WANT TO sEe ALIENs!!!
The voices do not match up with the video on this clip.
Why cant they talk faster.?????????
21.36 " I have special respect for Fergal"......immediately followed up with mocking his Irish accent and Irish people. Long gone is rule of the Catholic church, Ireland ranks 15th in world education....USA ranks 28th. Such asinine remarks by what I presumed was an intelligent guy. Rant over.
Did he say something snarky, like "planetary police" when referring to the older lady who asked a question...?
Oh man, the skins just keep getting thinner. I just assumed that was a reference to a lot of cloudy weather. Maybe something about religion, but I doubt it. That might be true for lots of places, but Ireland doesn't really stand out that much, at least in modern times. (And in old days, pretty much every country was religious.) OTOH you could argue the point on facts, as LA has constant smog, whereas when it's clear in Ireland, it's usually really clear.
@@ronaldgarrison8478 Ireland doesn't stand out much?? No, it doesn't stand at much if you look in the wrong areas. How would you define "standing out" might I ask?
@@krichard2346 Come on, it's plenty clear that I was referring to religion, when it's in the same sentence. Are you going to say Ireland stands out in being religious? Some pretty stiff competition, I'd say. Geez. Come on. I haven't got time for this.
@@ronaldgarrison8478 Not at all. Although 87% of Ireland claims Christianity, I really don't believe Ireland could claim to stand out as being religious. If anything, religion thankfully seems to be heading where it belongs, down the toilet. Religion did rule Ireland, it did so with fear and terror instilled into the Irish people. It was a cruel sadistic institution that would make members of ISIS blush if they knew of some of the atrocities carried out by the ruthless bastards. Also, it kept Irish people ignorant, under developed and backwards. I'm Irish and I have been told first hand many stories by my own mother and elderly people that filled me with nothing but anger and contempt towards the Catholic church and the despicable Vatican. Anyway, apart from my religious rant...... I have just listened again to confirm and it would seem I was completely wrong. He absolutely is referring to cloudy overcast weather and not religion. My 6 year old comment was incorrect. Such was my contempt towards the catholic church then, as it still remains I responded out of anger at the thought of Ireland still being perceived as a religious and backward country. Thanks for calling me out on it :)
wow just get people to sponsor it who own the companies you are ordering from for all parts for ships. Tell them they are holding us back because funding is not possible. So it will be on the company's to provide and invest. DUHHHHHH Sincerely, Deplorable and Sexy Scietist
O yeah, they are, actually written about in the book of Isiah, and Ezekiel. Ezekiel describes a round craft that flew back and forth like lightning. Not like a bat or a bird. I have no awards, I have no diploma, so my knowledge is irrelevant. And you can't even understand.
Chlamydia was on that tree of life lol
We will never go beyond our solar system. It is not possible.
👩🏻🚀🚀
Never will this evil dark sinful world be able till sin is killed once and for all.
You wont find LIFE in your Universe, NOT even on Earth !
Discover and Understand the DIFFERENCE, between the species (Including humans) and LIFE, (Awareness) which is Non-Dimensional and NOT part of this Universe.
Crop Circles?
We won't. Next question.
When Will We Find Life Beyond Earth?------ we will not
Not in the lifetime of anyone living today. Possibly never.
2027
not a joke, but the odds of finding intelligent life is 1- 700 Quintillion. Yes this is real number. IF its there, where are they?
P.S. I want to find it, it would be super exciting !!!
You calculated this figure how?
life is just the equal and opposite reaction to entropy.
Life doesn't violate entropy. A cell gets more orderly locally by increasing entropy in the rest of the universe.
Silly Effort To Investigate. Now who said that. ?
