IAstronomers have discovered a bright, mysterious geologic object in
radar images of Ligeia Mare, the second-largest sea on Saturn's moon Titan.
Scientifically speaking, this is a transient feature. They want to call it a magic island and so do we. Titan, the largest of Saturn's 62 known moons, is a world of lakes and seas. The moon – smaller than our own planet – bears close resemblance to watery Earth, with wind and rain driving the creation of strikingly familiar landscapes. Under its thick, hazy nitrogen-methane atmosphere, astronomers have found mountains, dunes and lakes. But in lieu of water, liquid methane and ethane flow through riverlike channels into seas the size of Earth's Great Lakes.
