Fortunately for Enceladus fans, the reality may be even cooler.  In a paper published Wednesday in the journal Nature, astronomers say that most of the material coming off Enceladus is erupting not in discrete geysers, but rather in long curtains that run the length of 75-mile long cracks in the moon's south polar region. The authors came to this conclusion after examining higher...
