This artist's concept shows OGLE-2016-BLG-1195Lb, a planet discovered through a technique called microlensing. The planet was reported in a 2017 study in the Astrophysical Journal Letters. Study authors, which included those from the Harvard-Smithsonian Center for Astrophysics, used the Korea Microlensing Telescope Network (KMTNet) and NASA's Spitzer Space Telescope, to track the microlensing event and find the planet.
