On Wednesday, Jan. 31, early risers will have the opportunity to see a celestial trifecta: a blue supermoon coinciding with a total lunar eclipse. The moon will be closer to the earth and brighter than usual as the eclipse nears, and it will also be the second full moon of the month. Astronomer Andrew Fraknoi joins Forum to talk about this rare lunar event. He'll also share some other exciting dispatches from the cosmos about the origin of gold in the universe, and "burping" black holes.
