Gliese 581c is a planet that was discovered a few days ago.
I saw it on T.V.
It is far from Earth, but very close in terms of planets and space.
It is about 20 light years from here.
It has an atmosphere, and might support life.
Some scientists think that there are many planets that we are yet to discover.
It is highly likely that aliens exist.
A few scientists, such as professor Hawking, think that aliens must exist, but that they should be avoided because they might be dangerous.
Life forms probably exist on other planets.
One difficulty we have finding planets is that our telescopes are not sensitive enough to see them.
I read a short article about it last week. (in the newspaper / on the Internet / in a magazine)
I heard that it is very similar to planet Earth. = I hear that it shares many similarities to planet Earth.
I read that there is a chance that there is life on the planet.
I wonder how big the chances of it having life really are.
Is it big news around the world? = Is it an important discovery?
Does professor Hawking think that aliens exist?
Yes he does, well, he thinks it is highly probable that they exist.
It is more probable that they exist than that they do not exist.
He also says that it is highly likely they are hostile, so they are best left alone.
Hostile = Not friendly.
But there is no reason for them to not like us.
Yes, but he says that they probably need our resources.
He further supposes that there large space ships of aliens looking for resources.
