Astronomers have found a rocky and possibly Earth-like planet circling the star closest to the sun. On Friday, the German magazine Der Spiegel reported that the European Southern Observatory's (ESO) La Silla Observatory in Chile had spotted evidence of a rocky, potentially habitable world orbiting Proxima Centauri, a small, dim star that lies just 4.25 light-years from the sun. Scientists with the ESO will announce the find later this month, according to Der Spiegel, which cited an unnamed astrophysicist on the discovery team as its source.
Andrew Fracknoi, professor of astronomy at Foothill College, joined us to discuss this.
