What Is the Habitable Zone?

There's a helpful concept we use to help understand what distance from a given star you might expect to find planets with liquid water on their surface – liquid water being essential for life as we know it. It's called the habitable zone. Every star has a habitable zone, but where that zone lies is different for stars of different sizes and brightness.

Imagine being a part of the generation of humans that are alive when another form of life is found and contacted

“The wet stuff itself, water”
Did NASA confirm that water is wet?

I remember watching something similar to this in documentary when I was a lot younger. Space will forever be amaze me. 😁

More relatable than science teaching in school

[rojeezee]

I learned more about Astronomy in this 2 minute video than I learned in 17 years of public schooling.

I would love if you combined some of these ideas, and basically pay people to write video essays on space.

In 140 seconds I know what the habitable zone is, and school would probably take a week to teach you that.

If they showed this in my science class we would have finished an entire unit in 2:20...

I still think it's mind boggling just to have video feed from the surface of another world, in our present time. A place where no human history has been written yet. Trying to comprehend a future where planet hopping is the new norm, expanding our mind to look to the galaxy and not just what's beyond the clouds. Amazing.

Thank you for the "... Life as we know it". Too many omit the "as we know it" bit, too often. 😉👍

I'm 14 and I have a best friend we're joining NASA one day!!! we already know a alot of stuff about blackholes, whiteholes, supernovae and other stuff

[andresallegre]

man if im not alive by the time something like this gets discovered i do not want life

[rbkstudios]

Those are some pretty amazing narration skills

[Cheesepuff]

Crazy that their could be a planet out their with life on it that also has a moon with life on it, and one day one of them would visit/would’ve have visited the other

[PedroAmA]

Why didn’t these video exist when I was studying many yrs ago from now ! Love science and tech

[AlexLexusOfficial]

Oh man, this is insane, imagine being an alien on Proxima B and trying to find us
