Show Notes
What does Jupiter's volcanic moon Io have in common with one of the largest stars in the galaxy? Both are belching sulfur compounds, though for very different reasons. We learn about sulfuric outgassing on Io and the incredible hypergiant star VY Canis Majoris and its huge stellar eruptions. Plus, the European Space Agency is building a probe to hideout in space hoping to catch a passing rogue or long period comet. Join us for all that, plus space news and trivia.
