Famed physicist and SETI pioneer Philip Morrison has passed away at 89. He is remembered fondly by Harvard physicist and SETI researcher Paul Horowitz, and former JPL Director Bruce Murray. Emily Lakdawalla explains the auroras visible on this planet and elsewhere. Bruce Betts is full of neutrinos on What's Up, and so is his new trivia contest.
