A computer model based on our best data about Saturn’s cloud-shrouded moon says that torrential liquid methane pounds the surface far more frequently than previously expected. Sean Faulk and Jonathan Mitchell of UCLA explain. The Planetary Society’s Jason Davis takes us to another ocean world that will receive a visitor in the mid-2020s. A total lunar eclipse arrives on the last day of January. Bruce Betts helps us prepare in this week’s What’s Up.
