Scientists just discovered three nearby planets that could support life

Astronomers at the La Silla Observatory in Chile discovered three planets orbiting a dwarf star called TRAPPIST-1. These planets are much closer to TRAPPIST-1 than Earth is to the Sun, but because TRAPPIST-1 is much cooler than our Sun, scientists say these three planets still may have an environment capable of supporting life.
