Quote: "From the tiniest throbs and wobbles of distant stars they can infer the size and character and even potential habitability of planets much too remote to be seen- planets so distant that it would take us half a million year in a spaceship to get there."
Comment: It's so interesting that space technology has advanced so much that we can view and understand planets and stars so far out of our solar system as opposed to before when we could just barely understand the planets near us.
Connection: I say a movie about the Hubble telescope, and how it can see farther than any other telescope and see stars millions of light years away.
Question: If astronomers can tell the habitability of planets so easily why is it taking so long with mars?
