NASA's search for habitable planets and life - Gary H. Blackwood (SETI Talks 2017)

[@Grinsekatze113]

talk starts at 8:10

[@MrTorleon]

Thank you for a fascinating and interesting talk, well presented with clarity and great supporting visuals.

[@palfers1]

Very comprehensive, educational and uplifting. Thank you.

[@adge610220]

Great talk and questions! Thanks.

[@keybutnolock]

Talk starts 00:08:12 but the intro is worth one watch !

[@keybutnolock]

WATCH AGAIN ! Thanks SETI

[@Aluminata]

Really insane they can visibly see planets around a star 140 light years away!

[@zaboomafia]

I'm looking forward to seeing images from the James Webb Telescope.

[@alangarland8571]

Yes, with present instruments we can only make a guess that something is there (probably).

[@nicosmind3]

@@alangarland8571 theyre not guessing but inferring, and then after they see the signal multiple times others confirm after them. For a single planet to be a false drop in light for whatever reason (sun spot, interference) takes big odds.

[@Kimhjortsbjerg]

I don't think so , can you prove it ? The earth from e.g. Mars is hardly visible ! Do you know how many km. 140 light years are ?

[@anthonymannwexford]

Great talk. Thank you SETI...

[@nicosmind3]

Que lastima que este canal no sube vídeos como el pasado

[@seangp3837]

Suppose you find one that orbits another star, how do you get there with your current primitive technology? That would be an interstellar travel.

[@upchurch231]

You dont.

[@ancalites]

should have millions of views

[@saatorto2533]

Habitable planets may mean- habitable for us ??

[@JustOneAsbesto]

The weird thing about this one is that I really enjoyed the lecture, but once he got into the questions it was like "Oh. So this is a guy who sure knows some science, but the real reason he's here is as a PR guy for NASA as a sort of token gesture to apologize to the SETI community for NASA never spending any money on SETI (but especially not now because Trump, amirite, lol)." Edit: As an aside, I don't really get why people think Trump will be so bad for space science funding. We just need to convince him that the miracle cure for having small, uh, hands... is on Mars... "Oh shoot, Don, it wasn't on Mars?? Let's try Europa! It's gotta be under all that ice somewhere, Donny!"

[@JustOneAsbesto]

In all seriousness Trump finding life elsewhere in the solar system is probably the only positive legacy he could ever possibly have. So he should get those programs running.

[@madanapallimadhusudanarao3741]

Great seti

[@zerstreutful]

The introducer doesn't give up talking!

[@Jenab7]

Hm. The introducer had an introducer.

[@username6135]

Did native Americans or Europeans find any evidence of life on the other side of the planet prior to their discovery?

[@biancabeluga1597]

Great!!😀👍

[@zaboomafia]

love this 43:15

[@ferdinandawn2555]

Our signal of tv and radio are traveling un the space for about 70 years aprox, if an alien advanced civilization is located about ten million Light years..do you really think we Will contact them? When our signal arrived maybe the earth existe no more...

[@MultiBikerboy1]

ferdinand awn ....keep up with ‘to the stars academy ‘ there is much to take on board.

[@zaboomafia]

#Coronagraphs Very Cool! 47:05

[@butt47jk]

This guy could easily pass as a leader of a Western country. It's his whole demeanor.

[@quosswimblik4489]

wouldn't a life using tools well on some heavier planet with the right conditions have 6 limbs not 4 2 being arms because it would need more strength to hold it self with that gravity and DNA itself would learn to use different insect advantages onto new creatures to fit the environment over millions of years or AI bolstered 200 years.

[@primemagi]

Some one should tell them about Earth. it is habitable and has life. they do not have a clue about internal structure or how life started. they are not interested to find out. they prefer to re-invent the wheel. MG1

[@politicallycorrectredskin796]

Love the five minute PR talk for a long-failed British neo fascist economic program. So inspiring. The whole thing is just bizarre. A PPP fluffer comes up to talk about inflatable planetariums and please give us money, before (eventually) introducing the person who is just there to introduce the person who is supposed to give a talk. America is just a study in absurdism.

[@nicosmind3]

Hows this for a derinition of a planet, considering exoplanets and our desire to colonise them. *A planet is able to hold on to an atmosphere within the habitable zone.* Which means the likes of Pluto isnt a planet, and Mars is halfway between planet and dwarf planet. A body without an atmosphere is pretty much like living in space. And you cant terreform a planet without an atmosphere as it will require too many resources, too much time, and they will lose that atmosphere anyway making the process pointless.

[@nicosmind3]

@@BLRSharpLight Well I didn't say we'd be doing it soon, and the timescale doesn't matter anyway. Having foresight is important I think. Like people talk about using the water on the moon for fuel. That seems like a waste to me unless you can easily replace it. Best use for regular human use when we eventually colonise it. Second we have the technology to colonise Mars now, it's just not built. And Falcon Heavy, as well as other rockets can deliver to Mars. But on to the main point. Colonising space. Are you aware that nuclear propulsion is estimated to get us a fraction of the speed of light? We could send satellites out to our nearest stars within human lifetimes and explore those systems. Project Orion was designed in the 60s and had an estimated speed between 2-10% the speed of light, building it to standard engineering standards. Ie like you would build a bridge or submarine. If you used modern materials and launched from the moon imagine the speeds you'd get then!! Way in the future but if people were motivated they could easily start today!

[@jonseymourau]

Yelped SETI?

[@zaboomafia]

Yelp is an app to search for businesses (e.g. restaurant) in your area.

[@chrisjordan7739]

What arrogant announcers they put me off before the start of the talk....is this how NASA is run, no wonder why is doesn't achieve?
