Tiny moons and supermassive black holes

If you stood on Jupiter you could see many moons above you, some so small that they have been heretofore invisible to scientists from Earth. As instrumentation gets better we can find smaller moons orbiting Jupiter, and some 64 have been discovered to date. Also Derrick and Dave explore The digestive emanations of the black hole at the center of our universe. And don’t miss what’s in the night sky this week. All this and more on this week’s Sky Talk.
