"What will happen to the Earth when the Sun dies?" (Ask an Astronomer)

[khuhjg7]

she forgot one phase after the sun turns into a white dwarf it will go out and turn into a black dwarf

[nickmaster271]

in 5 billion years we would have found another planet like earth

[frogfan101]

WRONG, 2 HYDREGEN ATOMS MAKE HYDREDGEN-2 (DUETERUIM), AND 2 dueturuim atoms make a heluim or 4 hydregens make a helium.

[Samtheman2001]

I wonder what our suns nebula will be like. Solar System Nebula? Sol Nebula? Nobody knows for sure.

[randy95023]

About a million other things will occur in the next Billion years to exterminate human life, so worrying about the Sun taking us out is not only too far away in time, it's not as relevant as the Life Ending asteroids and comets that will strike every couple of hundred million years or so... Hate to be such a "Gloomy Gus", but enjoy your life NOW and leave these kinds of worries to academia!

[Watrmellom]

its a good thing i wont live for 5 more billion years!

[SincerelyNise]

planets:pluto,you lucky bastard

[OverlordYesh]

1:55 :3

[razorraxor]

space objects move farther and farther,dont worry

[kiddolols]

awww helium is such a clown

[TheCatloverCG]

i know this isnt about the question but, if VY carois Majoris became a red giant what would happen?

[TiduS4max]

@TheCatloverCG it is a red hypergiant i think

[GuitarzMyThing]

"Or it will expand just enough to leave the earth intact while roasting everything on its surface to a crisp"

...Well that's always nice. O_O

[REDTEAM22003]

Ask An Astronomer: Is the host a ugly woman or a pretty man?

[vlad007001]

dudes!!! it said 5 billion years not 2 days so in 5 bilion years we will habit in other planets beyond earth

[5355vbxjbj76rvn]

Would it be possible for the human race to go into the earth, instead of living on the surface ? We would all become Morlocks eventually, but we would be alive (sort of)

Maybe it would be a good idea to concentrate on time travel. If we could travel into the remote past, our problems would be in the remote future.

[GeorgeNada1]

@5355vbxjbj76rvn we could move into the earth but it wouldnt do any good...the sun would be gone.. if we didnt get completely cooked in the process it would become so cold that nothing could live... once the sun goes theres no point in stickn around... we got a few billion yrs to figure it out though so get to work!

[BobFang3]

Hell, Now I just pissed myself because I found this interesting.

[Moirera]

Well... to be fair, we only have 500 millionish years till the suns energy starts to boil away all the water and thus make earth life impossible. That's still an unimaginably long time to survive for a species and is so far off it doesn't warrant any real concern at the moment...

But we will have to move long before the sun starts dying. Then we just have to dodge the galactic collision soon after >.<

[ApertureScienceLabs]

Incorrect at 0:46. The Sun is only 6,000 years old, just like EVERY other star, planet, and moon. So if your estimated Sun lifetime is ten billion years, then it has...ten billion years left.

[SpaceTime4D]

@ApertureScienceLabs Where the heck did you get 6,000 years from?

[ApertureScienceLabs]

@SpaceTime4D are you kidding me? If you're actualy as dumb as she is, then I got it from the Fact of Creation, seen in the Bible.

[MagiqDust]

okay...

-5 billion years later- time to pack and go to .... another planet.. or galaxy so i can live ^_^ -puts suit on and leaves on a spaceship then flies to a different solar system-

-lands on a different earth- Wow... i need to start having babies here.. what to do it with.. hmm.. -does with flower- -i have a baby- there we g- OMG ITS A BABY FLOWER! -throws-

[vergeloly]

i know that first machine of time is a photo camera. so sun is so far?

[08Hellboy]

Oi peeps, still think god exists?

[Shavarnarak]

It's biologically impossible for there to be humans in five billion years actually.

Even if humans survive as long as possible, evolution will take over and you end up with species DESCENDED from humans, that are no longer humans. A few million years (a FRACTION of five billion) is more then enough for homo sapiens to go away, leaving behind new species of hominids.

That is, IF humans live. I doubt it, overpopulation will kill the humans sooner or later.

[Shavarnarak]

@Shavarnarak

Heh, but still... lets say humans live somehow. Then five billion years... complex life has barely been around for a SINGLE billion years. Going from primitive quasi-fishy things and anomalocarids all the way to what we see today.

Who can honestly belief there'd still be humans?

At most, and that's a big if on it's own, there'll be unrecognizable creatures distantly descended from humans.

[clockclogs]

i mean 3:15

[Glennfalconi]

@clockclogs I didn't.

[clockclogs]

i loled at @3:17

[Glennfalconi]

' predict ' it will last that long. Lol. That thing can blow any moment. I wish i didn't find astronomy so intresting :(

[EllaFireHaHa]

@Glennfalconi I agree that astronomy is interesting, but I believe that its only rare occasions that it explodes before the red giant phase.

[Glennfalconi]

I wish i could live forever as 15 years old and travel to diffrent planets and see the old one blow up :) That unfortunatley is never going to happen. We are just made to shit on the planet so nice trees will grow on them. Thats the meaning of life.

[brambleclaw050]

maybe well find the speed of light travel in about 1 billion years :D

[flquadcamp]

How would the planets stay in the orbit if there is nothing big enough. Would Jupiter become sort of like the sun with all the planets now orbiting around it?

[Drachefeuerzwei]

Since stars convert hydrogen into denser elements, will there eventually be a time when there is no hydrogen left in the universe and thus no stars?

[JKTProductionzIncNCo]

yes IF we can survie another 5 bil years without killing ourselves off or suthin and our tecnology level keps increasing and accelerating then by tht time our descendants shuld be more than prepared to take on this problem , i mean c'mon "they" wont be humans anymore they would be far far more intelligent than us the earth is only about 5 bil yrs old thts only halfway molecular evolution has taken us another 5 bil yrs wow, our inteliigence would be like bacteria copmared to them/ peace dudes =:)

[OverlordYesh]

@JKTProductionzIncNCo ya. But that still doesn't mean we'll live, y'know, with WW3 and the illuminati.

[andyb9275]

plus, by the time the sun enters it's red giant phase, and if humans still exist then, we would of had 5 billion years to improve our technology, so before the sun dies,we might have a machine that prevents a star from yin g or give it more fuel. if not, we still would likley have technology to turn desolate planets into lush planets capable of sustaining life. i got this theory from the game spore.

[andyb9275]

when the earth is burnt completely, that would make saturn the third planet in the solar system, so wouldn't one or more of saturn's large moons be able to sustain life?

[SpitzerScienceCenter]

Some models predict that Jupiter's moon Titan would be in the habitable zone (the animation we used illustrates that possibility), but the red giant phase doesn't last long enough for us to expect complex life to emerge and survive. The thinner atmosphere that one of those moons would have if it were in the habitable zone would make it unsuitable for human life. We'll have to make other plans.

[quakize]

titan is saturns moon

[SpaceTime4D]

@SpitzerScienceCenter Titan is Saturn's moon, not Jupiter's.

[Genericprime555]

@SpitzerScienceCenter not jupiters moon,saturns moon

[SomeBigGay]

@SpitzerScienceCenter Saturn's moon is Titan, Not Jupiter

[PIMPBOLT]

@SpitzerScienceCenter I beg your pardon but Titan is Saturn's moon. Jupiter's moon is Ganymede, which is slightly bigger than Titan.

[dkj674523]

@SpitzerScienceCenter hey i got one question how many planets and moons are at the galaxy

[bandet888]

@SpitzerScienceCenter Titan is a moon of Saturn not Jupiter.

[rainyday219]

@SpitzerScienceCenter , Titan is Saturn's moon, not Jupiter's.

[AgentSuB4SuB]

@andyb9275 2nd

[dillasbebs622]

@andyb9275 No. The Giants: Jupiter, Saturn, Uranus, and Neptune are much farther apart than the inner planets: Mercury, Venus, Earth, and Mars. Also, none of Saturn's moons have all of the requirements for life, the way Earth does.

[monvergel]

Amazing info. Thanks for all your talents and efforts. More power.

[sushimagushi2]

wow
