KEP10: This June 2, 2014 handout provided by the Harvard-Smithsonian Center for Astrophysics, shows the newly discovered mega-Earth Kepler-10c dominating the foreground in this artists conception. Its sibling, the lava world Kepler-10b, is in the background. Both orbit a sunlike star. Astronomers announced June 2, 2014 that they have discovered a new type of planet -- a rocky world weighing 17 times as much as Earth. Theorists believed such a world couldnt form because anything so hefty would grab hydrogen gas as it grew and become a Jupiter-like gas giant. This planet, though, is all solids and much bigger than previously discovered super-Earths, making it a mega-Earth. AFP PHOTO/Handout/Harvard-Smithsonian Center for Astrophysics/David A.

Astronomers have spotted the "Godzilla" of all Earths, a huge rocky planet orbiting a star 560 light years away that is changing scientists' understanding of the origins of the universe.
