An article published in the journal “Nature Astronomy” reports the discovery of an exomoon candidate that was cataloged as Kepler-1708 b-i. A team of researchers led by David Kipping of Columbia University analyzed data collected by NASA’s Kepler Space Telescope with the specific purpose of looking for possible moons around exoplanets discovered thanks to Kepler. The Jupiter-sized gas giant Kepler-1708 b has a signal indicating the possible presence of a moon that would be a little smaller than the planet Neptune.
