    Great episode all! 😀 Hadn’t heard about Io’s collapsing atmosphere, so that was really interesting and Lucas did an ace job of explaining it. Thought that it was an great comparison between Sulfur dioxide being close to sublimation on Io and that of water being close to melting on Earth – another weird one is that the temperature on Titan (90 K) is just above the melting point of ethane. Now also wondering about the biodiversity of the little critters in my house!!
