You forgot to mention that about 99% of astronauts are in the military, so that’s pretty much a prerequisite to becoming an astronaut. NASA is a military administrative organization.
SETI was created to eavesdrop on terrestrial communications. They monitor a billion channels just in the tiny slice of EM spectrum that we use for communication. Every signal SETI has decrypted to date has been terrestrial in origin.
Just wanted you to know I Just sat here and watched all of your “Kids Questions” videos with my space-obsessed 5 year old nephew. He was enthralled with the way you explained things. When I went to show him another video about space he yelled, “NO! I only want the guy in the red shirt!” haha. Thank you for making science interesting. We made a homemade Space Camp bank last month and he has been saving up. I think we may have a little astronaut on our hands.
Hi, what would be the affects on earth if we got hit by a mass coronal ejection? if it was strong enough to penetrate the ionesphere would gamma rays give us radiation, or would it simply just knock out all our electronics? and is this possible it could happen?. thanx friendly guy.
What?! He wasn’t teached in school about other planets in solar system? After 1995 astronomers found other planets?!!!! Gimme a gun, I’ll shoot myself!
And Sedna. And Charon! And Ceres. Ceres was considered a planet once, then it was discovered that it was the largest member of a belt of objects, called “asteroids.” Same EXACT thing happened to Pluto.
If anyone still “thinks” Pluto is a planet, they HAVE to concede that Ceres is one too.
And since Pluto and Charon both revolve around a common center of gravity, you can’t regard either as the true dominant body; they’d have to consider Charon a planet too.
cool, he’s Harald Lesch’s younger brother ?! 5*****

Continued- Drake Equation only counts planets and not the moons that orbit those planets. We know from Jupiter and Saturn’s moons that they could have life, just like a planet IF they were in the “Goldilock’s Zone”. Multiply the end result of the Drake Equation by 400 Billion and it would be more accurate. Why didn’t Drake count for those moons?
We would have to be extremely arrogant to believe that WE are the only intelligent life in the Universe. There are probably many millions of advanced civilizations scattered throughout the many Galaxies. Inter stellar and inter galactic distances will probably keep us from communicating, let alone traveling to, other civilizations. The “Drake Equation” is purposely EXTREMELY conservative so people like Carl Sagan don’t look like “nuts” to the average Joe…
I always liked Carl Segan. I wish instead of dying of cancer he had lived to a ripe old age like some people do. Had that happened I would have loved to get to meet him.
And also the relatively short time period that an intelligent civilization exists. We’re just a flash of light going off in a universe with unimaginable time scales.
This presentation of the Drake equation, from the Cosmos series, is the best evidence for the possibility of alien life.
Notice: this is based only upon the number of stars in our galaxy; 400 billion.
This was done before the Hubble discovered that there are hundreds of billions of GALAXIES throughout the universe.
Statistically, alien life is virtually a guaranteed proposition. Seeing aliens on Earth is highly unlikely though because of vast distances and the limitations of light-speed.
just great higway of info.everyone apart from the bible thumpers know that we need science to further our knowledge of planetary formation for our own survival on this planet,,,as the only people in control of our destiny are us,,,whether we survive as a species or go the way of the dinosaurs ,,only our own understanding can save us ,,, the more we know the longer we will survive. Thank you.Carl Segan,NASA,ESA,& you *** SDESDE***

Thank you for answering these questions
Questions I have gotten from children while actually outside using a telescope:
“Do the stars burn out in the daytime when the Sun comes up?”
“That (Orion’s 3 belt stars rising on the horizon) isn’t stars, it is a radio antenna”
“How do you get your telescope in your car?”
“My daddy has one like that, but he doesn’t use it on the sky”
I once asked a friend, “did you hear? Pluto’s not a planet anymore!”
Her response was, “What, did it blow up??”

at about 7:00 you start to talk about the type of telescopes you had a a kid, i was wondering if you could maybe show us the telescopes you have now?
They’re yes or no questions, you idiot.
Damn , you’re really friendly
and sedna
Yeah, and Makemake and Haumea.
Although, if anyone even considers making Sedna a planet, he should be hung and dismembered. Just look at it’s crazy orbit.
high school teachers are dumb

But… they’re not.

It would be fun to throw water in the space
If Pluto would be a planet, then Eris would have to be one as well….
he still there you know? just because is not a planet anymore does’t mean you should ignore him
Pluto, may you rest in peace. It was nice knowing you.
Europa has sexy mermaids.
I already knew most of this stuff but it was entertaining. Subscribed, keep it up man
you should read this guys book its called death from the skies its about how the world will end like when the sun dies and stuff
yeah i love astronomy, but there are no classes at my school, so i took chem, and i love it now!!!
apogee is when the moon is farthest from the earth, perigee when it’s closest
what the difference between apogee and perigee

I’ve been there!!!! It is BIG! Then we went back to San Juan and got drunk.
Orion may help.
Agreed. It’s nice to believe in X-files fantasies, but the reality is that there is no real evidence of any alien visitors past or present.
There is no intellent life on Earth. Thus, we need to eliminate one possibility from this equation.
@OldSchoolSkill That, and the fact that WE are here guarantees it. It happened here so it’ll happen elsewhere.
And then you have the military industrial complex determined to help them blast us back to the stone age.

your just geussing and your calling that smart?
I enjoyed how Carl would get lockjaw three times during every sentence.
Spock’s uncle, Carl Sagan.
I wish you were still here with us.
R.I.P.
Where can I get the plans for one of these?
Nice video.
Carl Sagan’s ability to take what we know and make it so that everyone has a chance to see and hear it was his greatest gift.
I want to see some of the others that inhabit this universe!
What about the Koran thumpers? They seem like the group most determined these days to take us all back into the Stone Age….
