Mysterious Oxygen Abundance on Jupiter's Moon Callisto Baffles Scientists

Scientists have discovered an unexpectedly high amount of molecular oxygen in the atmosphere of Jupiter's moon, Callisto, which cannot be fully explained by prevailing theories. While the presence of abundant oxygen raises the possibility of supporting life, the moon's extreme cold makes it unlikely. However, the oxygen could be valuable for future space exploration. Researchers are uncertain about the source of the oxygen but hope upcoming missions will provide more data to solve the mystery.
