After nine years and the discovery of thousands of exoplanets, NASA announced today that its Kepler space telescope has run out of fuel. It is, apparently, the real, final end of a telescope that has had many near-death experiences over its lifespan.

Kepler will be remembered for discovering more than 2,600 exoplanet over its nine-year lifetime, sparking wonder and excitement with every haul. Now, when we look up at the stars, we know more than we ever have before—and we can daydream about what these thousands of worlds hold.
