Even astronomers find the solar system surprising. Astronomers in Chile have found 32 new “exoplanets” beyond our own solar system. Some of the newly discovered planets have masses 10 times the size of Jupiter. “This is really important because it means that low-mass planets are everywhere,” said one expert. The new planets bring the total number of known exoplanets to more than 400. The astronomers who found this recent group expect to find a similar collection within six months; the ideal result would be to discover a rocky exoplanet with temperatures that could sustain liquid water.
