Enceladus
Enceladus, an ice moon of Saturn that may harbor life in oceans of water miles below the "tiger stripes" you see in this image are from the warmest places in the south polar region. The image shows how these warmer temperatures correspond to the prominent, bluish fractures called "tiger stripes," imaged by Cassini's imaging cameras. The warmest temperatures, at 91 and 89 degrees Kelvin (minus 296 and minus 299 degrees Fahrenheit), are located over one of the "tiger stripe" fractures. They contrast sharply with the surrounding temperatures, which are in the range 74 to 81 degrees Kelvin (minus 326 to minus 313 degrees Fahrenheit).
From this photo above you can see water vapor being ejected into space from Enceladus. The Cassini space probe has made many discoveries about this moon. Cassini detected organic (carbon-containing) compounds, the building blocks of life, in the jets' plumes. Enceladus has the trifecta for life – water, organic materials and excess energy (friction heat generated from Saturn's gravitational pull), stated Carolyn Porco, leader of the Cassini Imaging Science team.
