But there\u2019s something they have yet to spot with any certainty: moons around those worlds.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Now a recent discovery around a Saturn-size planet 635 light-years from Earth offers one of the best potential clues that exomoons orbit exoplanets out there in the Milky Way. And this possible moon, as described by scientists, is putting on an explosive show, blasting volcanic matter and noxious gases that then drift off into its stellar neighborhood like a comet\u2019s serpentine tail.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">The possible evidence of an erupting satellite was described last month in <a class=\"css-yywogo\" href=\"https:\/\/iopscience.iop.org\/article\/10.3847\/2041-8213\/ad6b29\" title=\"\" rel=\"noopener noreferrer\" target=\"_blank\">The Astrophysical Journal Letters<\/a>. Astronomers have been observing a puffy planet named WASP-49 b for years, but the new paper argues that a sodium cloud whizzing around it does not come from the planet. It might be created by a hypervolcanic companion moon spewing 220,000 pounds of the material every second.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">The abundance of moons in our own solar system implies that exomoons certainly exist.
