The more we see other planets, the more the question comes into focus: Maybe we're the weird one? Decades of observing Earth from space has informed our search for signs of habitability and life on exoplanets and even planets in our own solar system. We're taking a closer look at what we've learned about Earth - our only example of a planet with life - to search for life in the universe.

Since 1992, there have been more than 3,600 confirmed exoplanet discoveries in more than 2,700 star systems.
