STScI, Baltimore, MD-(ENEWSPF)- Using NASA's Hubble and Kepler space telescopes, astronomers have uncovered tantalizing evidence for what could be the first discovery of a possible moon orbiting a planet outside our solar system.
This moon candidate, which is 8,000 light-years from Earth in the Cygnus constellation, orbits a gas-giant planet that, in turn, orbits a star called Kepler-1625. Researchers caution that the moon hypothesis is tentative and must be confirmed . . .
