The odds are that life is out there – but rather than little green men, it may look more like hydrothermal vent tubeworms ...

With Area 51 ruled out by President Obama, where might aliens really be hiding? Scientists have now revealed the best candidates.

Cassini mission data shows Saturn’s moon Enceladus generates Alfvén waves extending over 504,000 km, circulating energy and momentum through Saturn’s magnetosphere, according to Universe Today and ...

During its final Grand Finale phase, Cassini performed death-defying maneuvers through Saturn’s rings and over its poles, ...

The Science: Europa has been considered as a top contender for alien life for even longer than Enceladus, thanks to its massive under-ice liquid water oceans. It also displays water vapor plumes ...

Enceladus’s geysers power vast electromagnetic wave systems that redistribute energy throughout Saturn’s magnetosphere.

In 2004, NASA scientists proposed that Enceladus, a small frozen moon orbiting Saturn, could hide a global ocean under its ...
