Saturn's moon Enceladus looks to be warm and wet beneath its thin frozen skin, and
according to a new study, it's possible the distant world's internal heat source has been in place for billions of years -- long enough for some kind of alien aquatic life to evolve beneath its icy shell.
Enceladus and the mysterious plumes of material that issue forth from cracks in its otherwise wintry surface have fascinated astronomers and astrobiologists for years. In 2015, NASA's late Cassini spacecraft cruised through the spray to see what information it could collect. Analysis of the data gathered that day led to the exciting announcement earlier this year that Enceladus' hidden ocean appears to possess the chemistry and heat source needed to support life. Notably though, no evidence that life is actually present has been found just yet. https://www.cnet.com/news/saturn-moon-enceladus-nasa-alien-life-ocean/
