No, only ecological types 9-17
No. Rigel is a star. Any aliens would have to live on a planet.
No. There is no evidence of life on Mars.
We have not yet made contact with any aliens.
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.
Aliens are living things that live on any planet and martian describes any thing to do with Mars.
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.
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 not known whether there are living beings on any other planet. It may seem likely that there there is life on some planet other than Earth, given the huge amount of planets, but this has not been confirmed.
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.
