In a surprise find, astronomers have discovered a planet possibly covered with oceans of magma “right around the corner.” Thirty-three light years away, “we have a sub-Earth-sized planet that’s slightly larger than Mars and essentially right around the corner, at least on a cosmic scale,” said Kevin Stevenson, a planetary scientist now at the University of Chicago UCF-1.01 …

Astronomers have detected our “grotesque” twin: A planetary system arranged much like our own solar system, a new study says. Dubbed GJ676A, the system has two rocky planets orbiting close to its host star, and two gas giants orbiting far away. This means the system is arranged like our system—though in GJ676A, everything is much …
