A SUBSURFACE OCEAN AND WATER PLUMES
SATURN'S MYSTERIOUS MOON, ENCELADUS: In 2005, scientists using NASA-ESA's Cassini spacecraft detected plumes of water vapor and organic gases above Enceladus' south pole, suggesting that a deep liquid ocean lies beneath its icy surface. The Goddard-built and -managed infrared spectrometer on Cassini discovered warm temperatures in the vents that release these plumes. |
