Given everything humanity has learned about the Universe, it seems wildly improbable that Earth would be the only planet out there with life on it. Earth is just one of many worlds in our Solar System with a rocky surface, a thin atmosphere, and water — potentially even in the liquid phase — on or beneath its surface. Our Milky Way itself contains hundreds of billions of stars, nearly all of which have planets, some of which may be habitable or even inhabited.

And beyond our Milky Way, there are some two trillion galaxies strewn across the observable Universe. The raw ingredients for life, including the atoms and organic molecules all known biological processes are built from, are found everywhere we look, from inside meteorites to gas clouds in interstellar space to the protoplanetary disks that form new stars. The question shouldn't be whether there's life out there in the Universe, but how we'll first find it.
