Surprising discovery on Rhea marks first time such an atmosphere found on a Saturn satellite

Saturn's second-largest moon Rhea has a wispy atmosphere with lots of oxygen and carbon dioxide, a new study has found.

NASA's Cassini spacecraft detected Rhea's atmosphere during a close flyby of the frozen moon in March. The discovery marks the first time an oxygen-rich atmosphere has been found on a Saturn satellite. [ Photo of the Saturn moon Rhea.]

Oxygen atmospheres are known to exist on other natural satellites in our solar system. For example, Europa and Ganymede two frigid moons of Jupiter are also rich in oxygen.

But the discovery on Rhea suggests that many other large, ice-covered bodies throughout the solar system and beyond may harbor thin shells of oxygen-rich air and, perhaps, complex chemistry, researchers said.
