In 2015, astronomers have been trying to find the cause of Tabby's Star's mysterious behavior. The star keeps dimming in an oddly sporadic pattern, and has overall gotten 10% less bright in just a century. Some scientists have suggested an alien megastructure or a massive swarm of comets may be to blame. In 2019, a team of astrophysicists at Columbia University proposed a different culprit. The star have have stolen icy moons from an orbiting planet. Over time, radiation dissolved these moons, creating a dusty cloud that blocks some of the starlight.
