"Are other solar systems like our own?" (Ask an Astronomer)

[randy95023]

We have already discovered many Gas Giants orbitting their stars in the Goldilock's Zone.  We rule out life on gas giants, but we know from Jupiter's example that Gas Giants should typically have several moons. If Jupiter were in Earth's orbit there's a stronger chance that its moons would have life. The Drake Equation doesn't seem to calculate for the large moons of Gas Giants having life. I think Life is probable in a lot more places than we currently think. Am I wrong about this?

i saw this today at school

[AdamH1029]

anyone else notice the death star at 0:16?

@AdamH1029 thats mimas.

[brinztar]

wow, scientists have found so many earth-like planets now. this video must be old.

[MeatProdux]

there's probably been plenty of planets that have had life and no longer exist, and there's probably plenty of them out there right now that have life. probably

There's always a star similar to a star or a galaxy to a galaxy or a solar system to a solar system and even a planet to a planet specifically. The only thing i can say is in such a vast universe i doubt there's any exceptions in similarity including our very own blue marble.

the intro pissed me off a little.

@Wesley296 it reminded me of animal crossing...

[MapleStoryP]

lol, i'm sorry dave

[canuckman87]

there is probably trillions of earth-like planets.

[yomoma1103]

cool, there could be other planets like earth

[justinpatrick550]

@yomoma1103

Ok theres a earthlike, Gliese 581.

Very interesting. I've just recently become amazed by astronomy (galaxy's, our universe, etc) I'd be real curious to know what is directly above us (when we look straight up)Are we looking at the fat side / size of our galaxy, etc.. I guess when I try to picture millions of light years, I for some reason look at the horizon (not directly above) I wonder if other people do that, for some reason I feel directly above must have a "cap". (of a few light years)I know it doesn't though
