We have not yet made contact with any aliens.
No. Rigel is a star. Any aliens would have to live on a planet.
It is not currently known whether there is life on any other planet.
We are not aware of any aliens on Mars or anywhere else.
No. There is no evidence of life on Mars.
In my opinion, i think aliens are never real. Well, some people believe in these stuff ,but if you take my opinion, i would say that aliens don't exist. And not in this liftime and not on any planet............
no because aliens uvaded the planet and ate it. :)
It is doubtful that there are any baby aliens on Pluto, for numerous reasons. One is that it is unable to support life; and the other is that, due to its harsh climate, any baby aliens would actively seek out a better planet on which to grow and mature. It is unknown whether any adult aliens currently reside there, but all available evidence makes it rather doubtful.
That's a big no. No aliens. Nothing.
It is possible, but no one knows of any such planet. We don't know if there are aliens. Someone has to be the first form of intelligence in the universe, and there is no reason to think it isn't us.
No known planets have aliens.
As yet, humanity has found no signs of aliens (or any other life) on Mars, or anywhere else in the universe.
No, only ecological types 9-17
