NASA scientists have first suspected that Rhea has a thin atmosphere with oxygen and carbon dioxide, based on the observations of Jupiter’s icy moons by the Galileo spacecraft and Hubble Space Telescope. It was only now that they proved that their hypothesis was correct. According to the report transmitted by Cassini, the oxygen appeared to occur when Saturn’s magnetic field rotates over Rhea that eventually formed the moon’s water-ice surface.
