On October 30th, 2018, after nine years of faithful service, the Kepler Space Telescope was officially retired. With nearly 4000 candidates and 2,662 confirmed exoplanets to its credit, no other telescope has managed to teach us more about the worlds that exist beyond our solar system. In the coming years, multiple next-generation telescopes will be deployed that will attempt to build on the foundation Kepler built.
And yet, even in retirement, Kepler is still providing us with impressive discoveries. For starters, NASA started the new year by announcing the discovery of several new exoplanets, including a Super-Earth and a Saturn-sized gas giant, as well as an unusually sized planet that straddles these two categories. On top of that, NASA recently released the "last light" image and recordings obtained by Kepler before it ran out of fuel and ended its mission.
