In 2017, astronomers identified 1I/‘Oumuamua as the first interstellar object ever observed in our Solar System. While it lacked typical cometary activity, ‘Oumuamua exhibited a notable non-gravitational acceleration, leaving experts struggling to explain its origins. Previous models suggested outgassing of hyper-volatile molecules, but inconsistencies remained. In this video, we explore a new theory, by Dr. Jennifer Bergman and Darryl Seligman, that proposes ‘Oumuamua's acceleration was caused by the release of entrapped molecular hydrogen, which formed from energetic processing of an H2O-rich icy body.
