Why SETI Might Have Been Missing Alien Signals
A new study by researchers at the SETI Institute suggests stellar “space weather” could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma turbulence near a […]

Saturn’s Moon Titan Could Have Formed in a Merger of Two Old Moons
Recent research suggests that Saturn’s bright rings and its largest moon, Titan, may have both originated in collisions among its moons.
