Complex organic molecules have been discovered for the first time coming from the depths of Saturn’s moon Enceladus, a new study reported.
Alien life could potentially exist on the undersides of the icy shells of Jupiter’s moon Europa and other frozen worlds thanks to the intersection of chemical energy rising up from hydrothermal vents on the ocean floor and oxidants diffusing down from the surface, new research suggests.
“Super-Earth” planets are giant-size versions of Earth, and some research has suggested that they’re more likely to be habitable than Earth-size worlds. But a new study reveals how difficult it would be for any aliens on these exoplanets to explore space.
