Doubts Arise Over Existence of Proposed Exomoons

Scientists are skeptical about the proposed detection of exomoons, or moons orbiting planets outside the solar system. The research suggests that exomoons may only be detectable if they are extremely large. While there is no reason to believe that moons don't exist around exoplanets, finding them is challenging. Previous detections of exomoons around Kepler-1625 b and Kepler-1708 b are now in doubt, and the study also indicates that current technology can only detect particularly large moons in wide orbits around their planets.
