At least, none has been discovered so far.
Yes, but not on any of the ones in our solar system.
Yes, the planet Earth is part of the solar system, so all the life on Earth is in the solar system. Yes, our Earth is part of the Solar System. As to life on other planets - both within our Solar System and in other solar systems (planets around other stars), nothing has been proven yet, one way or the other. Specifically, no life has been found on other planets. It would seem probable, though, that what happened on Earth can happen again - perhaps on nearly any planet, perhaps only occasionally.
No, There isn't any life on the other planets.
The Mars theory was debunked, so no.
So far there has not been a trace of life on any other planet in our solar system. Earth is the only planet with life. Life is unsustainable on other planets because they are either too hot , too cold, no water, poisonous gasses, and a variety of other problems.
It certainly seems likely that life should have appeared elsewhere in the Universe - considering the huge amount of planets in the Universe.On the other hand, so far we have no confirmation of any alien life.
The solar system is not part of any other star system. It is part of a galaxy called Milky Way.
It is highly unlikely that any other planet in our solar system will. That does not preclude the possibility of life being elsewhere in the universe.
Not that the US know of but there have been reportings of UFO's and stuff like that. So really it's unknow to us about any other life forms.
Saturn has more moons than any other planet in our solar system
There are no galaxies in our, or any other, solar system. They are far too large.
So far as is known to date there is no life on any other planet in our solar system or elsewhere. That does not rule out the possibility that life may exist on other planets
