Saturn Moon's Activity Could Be 'Curtain Eruptions'
Pasadena CA (JPL) May 09, 2015
New research using data from NASA's Cassini mission suggests most of the eruptions from Saturn's moon Enceladus might be diffuse curtains rather than discrete jets. Many features that appear to be individual jets of material erupting along the length of prominent fractures in the moon's south polar region might be phantoms created by an optical illusion, according to the new study. "We think most of the observed activity represents curtain eruptions from the 'tiger stripe' fractures, rather than i ... read more
