  • one oxygen ion for every 2,550 cubic feet (90,000 cubic meters
  • still enough to qualify as an atmosphere
  • announced Friday (March 2).
  • Dione, in addition to Saturn's rings and the moon Rhea, is a source of oxygen molecules
  • shows that molecular oxygen is actually common in the Saturn system and reinforces that it can come from a process that doesn't involve life
  • Dione is one of Saturn's smaller moons

  • orbits Saturn once every 2.7 days
  • distance of about 234,000 miles (377,400 km)
  • roughly the same as that between Earth and its moon
  • The oxygen on Dione may potentially be created by solar photons or high-energy particles that bombard the Saturn moon's ice-covered surface, kicking up oxygen ions in the process, Tokar explained.  Another idea suggests that geologic processes on Dione could feed the moon's atmosphere, researchers added.
  • atmosphere on Saturn's moon Rhea — one similar to that of Dione — was also detected in 2010
  • Dione was discovered in 1684 by astronomer Giovanni Cassini
  • named after the Greek goddess Dione, who the ancient Greek poet Homer described as the mother of the goddess Aphrodite
  • launched the Cassini mission in 1997 and it has been orbiting Saturn since its arrival at the ringed planet in 2004
