Three Potential Earth-like Planets Discovered Around Nearby Star

Three new planets discovered around a tiny, faint star in the constellation Aquarius may be among the best places to look for evidence of extraterrestrial life. A team of astronomers led by Michaël Gillon of the Institute of Astrophysics and Geophysics at the University of Liege in Belgium studied the star, named TRAPPIST-1, and discovered it…
