LIFE? WHERE???

ever watched on of those old movies about alien invasion, and you would get scared and not be able to sleep at night? then, your parents would tell you 'it's just a movie, there are no such things as aliens' Well, they might be wrong. if you think about it, the universe is HUGE, there are do many places that there has to be somewhere that has the earth-like place, but the thing is is that we don't know.
Now, letSee full size images talk if there is a chance there could be life on Ganymede. On, ganymede, the crust is dry and cold. There is liquid to icy water in the outer layer, which takes up a lot of the inside of Ganymede. But beyond that the core is solid, because of the pressure the moon has. The only place that can have life is on the liquid outer core, but to me, I don't think there is (oh well). But on Titan, a moon of Saturn could be able to have life, most of it is ice but sciantist think there could be an ocean under the icy crust.

BUT, there is a place where life really could exist. It is called Gliese 581d, it is in orbit of a red dwarf star 20.5 light years away. it is a big planet and it said to have an ocean in it as well as protection from a bigger planet, and not to extreme temperatures. But it doesn't look like we will be visiting it soon because it is too far away from us.
People are still discovering new things about planets and moons that might just be able to have life on it.
