The world’s most powerful solar telescope has just been renamed for the man responsible for its creation. We’ll meet astrophysicist and helioseismologist Phil Goode, and we’ll enjoy a tour of the Goode Solar Telescope. All you need to safely enjoy the coming Great American Eclipse are a couple of pieces of cardboard and a pushpin. Emily Lakdawalla explains. A discovery at Saturn’s moon Titan has Bill Nye thinking again about the discovery of life elsewhere in the universe. With an eclipse and a meteor shower on deck, Bruce Betts has much to share in this week’s What’s Up.
