Astronomers spot evidence of volcanically active exomoon

Science
Aug. 29 (UPI) -- Scientists may have found a volcanically active moon outside our solar system. Hints of the moon's presence were discovered hiding in the WASP-49 solar system. Astronomers likened the moon to Io, the most volcanically active body in our solar system. They also likened the moon to a satellite from Star Wars, the planet Mustafar, where Darth Vader's castle is located. "It would be a dangerous volcanic world with a molten surface of lava, a lunar version of close-in Super Earths like 55 Cancri-e, a place where Jedis go to die, perilously familiar to Anakin Skywalker," Apurva Oza, postdoctoral fellow at the Physics Insitute of the University of Bern in Switzerland, said in a news release. Though researchers aren't conjuring the so-called exo-Io from thin air, it's possible ...

Oct. 3 (UPI) -- The existence of a large exomoon orbiting a gas giant located 8,000 light-years form Earth best explains a unique pattern of stellar dimming observed by both Kepler and the Hubble Space Telescope. "We are unable to find any other single hypothesis that explains all the data that we have," astronomer David Kipping told reporters during a phone call earlier this week. Kipping and his colleague Alex Teachey, both researchers at Columbia University, detailed their investigation of the Hubble and Kepler data in a new paper published Wednesday in the journal Science Advances. The duo began their research by surveying 284 Kepler-discovered planets with long orbits. Planets too close to their host stars are less likely to feature moons. Of the 284 candidates, one stood out. The tr...
