On December 18, 2019, a star in the Large Magellanic Cloud brightened and dimmed symmetrically over one hour, detected by Chilean observatory telescopes. The phenomenon, explained by gravitational microlensing, suggests a very light object (about 3 lunar masses) passed between Earth and the star, ruling out typical stellar black holes.
