Titan Weather: Cloudy Every 15 Years
There is only one moon in our solar system that has clouds, Saturn’s giant moon Titan. First discovered by a scientist using an earthbound telescope, the clouds were later confirmed by NASA’s Cassini spacecraft. Chris McKay, a planetary scientist at NASA Ames Research Center, recently gave a public lecture, sponsored by the Planetary Society, about what scientists have learned about Titan from the Cassini-Huygens mission. In this, the second part in a four-part series, McKay talks about Titan’s mysterious clouds, some of which are thought to appear only briefly every 15 years.
