Do We Live in the Rarest Solar System In The Universe? We're about to find out!

Season 11 Episode 17

There are lots of reasons to search for planets around other stars—exoplanets. A big one is to find other places in the universe that might harbor life. We only know of one such planet so far: Earth. And so we get particularly excited when we find Earth-mass planets at the right distance from their star to sustain liquid water—also critical for life as we know it.
