New images of Jupiter's volcanic moon Io show "hotspots" happening in different spots on a volcanic lake. Even more surprising given the lake's small size: the images were taken from Earth.
11 June 2015, 07:14 AM ET
Fifteen-year-old Tom Wagg first spotted the Jupiter-size exoplanet two years ago. Further observations have now confirmed the existence of WASP-142b, which lies about 1,000 light-years from Earth.
11 June 2015, 07:00 AM ET
