Finding "Tatooine" - How Did Astronomers Do It?

[funsciencecal]

@Terfew i am 14 years old and really into astronomy aswell, it is truly the best ever! I have big dreams and i hope i will be a astronomer one day.

@funsciencecal You don't have to wait. If you can see the sky (or see the Internet!) you can observe, learn, dream, study, love... Don't delay. The Universe is waiting for you!

[megadeath45]

Fuck Tatooine. Let's find Pandora!

[Heartwing13]

Can I just say that they really should have mentioned Gallifrey?

[sedgie09]

it is out side of the habitable zone of the stars which is the region where temperatures are right for liquid water to exists on the surface of the planet.

Since it is made of gas, Kepler 16-b may not harbor life. but wait a minute didn't he just say that its the right temperature for liquid water to exists and as we all know nearly 85% of life is made of water so when there is water there is life. I wouldn't say it can't harbor life. if there is water on there there's bound to be some form of

[sedgie09]

@sedgie09 life. anyways interesting stuff iv all ways been into this, and would love to get into astronomy in with the experts and talk about it. anyways with the theme of star-wars/Tatooine

MAY THE FORCE BE WITH US ALL.

Wait.. what if it's just the planet and the star is orbiting the bigger star (not sure which is which)... it makes more sense.. because technically speaking if the planet was indeed orbiting two stars it'd be going in a figure 8?

[VideoFromSpace]

@trashthethrasher The planet will orbit the common center of mass of the two stars; which, in this case, is a point between the two stars.

[trashthethrasher]

@VideoFromSpace But the orbit isn't between the two stars, in it? O.o According to animation..

[VideoFromSpace]

@trashthethrasher The common center of mass is a point in space between the two stars. The planet orbits that point - far away from either star, revolving around both of them. That's what you see in the animation.

@VideoFromSpace

Physics for the WIN!

Its just like the center of mass between Earth and the Moon, except our center of mass is still on Earth. Right or am I terribly wrong?

[VideoFromSpace]

@johnyjoe2k You're terrifically right! The center of mass of the Earth-Moon system lies within the Earth. [The Moon is roughly 1/100 the mass of Earth.] But in the Pluto-Charon system, the center of mass lies outside either body, making it a "binary planet" or "double planet" (technically a "double dwarf planet"); the only one in our Solar System. At least the only one we know of so far...

This an amazing channel, i'm 13 years old and i'm getting into astronomy. I have a great telescope I set up and every night i go out and search the night sky for planets. I want to study to learn more about space, just thinking about how many GIANT super stars and planets are out there makes me feel like a spec of sand. It's unbelievable, and watching this channel helps me learn more about everything space! thank you so much

[VideoFromSpace]

@Terfew Thank YOU for watch us! Stay with your dream. You WILL get there. We did...

[AizenSamaKingX]

People, this is planet Nibiru and Nemesis approaching on schedule.

[VideoFromSpace]

@AizenSamaKingX Oh, for cryin' out loud. What does it take for you people to LET GO???

[guaranic]

@VideoFromSpace nothing will ever stop one who's committed

[ChesoXD]

i am so amazed by these videos im only 14 but i wish to be a astronaught when i am older .

[SodapopSays]

yay starwars

[Djrowling]

I love this channel

[VideoFromSpace]

@Djrowling Thanks! And we kind-a like you, ya know?

[moochabod]

with two suns, would the planet have to be twice as far away to sustain life?

[VideoFromSpace]

@moochabod Nope. Researchers think the habitable zone is not very difficult to calculate, since much is know about both stars in the binary system.

[moochabod]

@VideoFromSpace i don't get it. so if we had two suns, we'd survive if we stayed the exact same distance away as we are now? wouldn't that be twice as much radiation?

[purplefox17]

thats cool
