More At: https://newatlas.com/titan-summer-rains/58083/Titan, the largest moon of Saturn, is a surprisingly dynamic world, with a thick atmosphere and surface oceans of liquid methane. Like the fictional land of Westeros in Game of Thrones, seasons on Titan last about seven years, and summer was due to hit its northern hemisphere in 2016. But strangely enough, it didn't seem to arrive as expected. Now, astronomers have analyzed Cassini images and found evidence of rainfall, indicating that finally, summer is coming.
When Cassini first arrived at Titan in 2004, the moon's southern hemisphere was enjoying summer, and the spacecraft observed cloud coverand rainfall over that half. Astronomers developed climate models of Titan from Cassini data, which predicted that similar weather would be seen across the northern hemisphere as the seasons changed.
