Yellowstone national park is famous for its hot springs, geysers, and picturesque vistas. However, it’s the supervolcano lurking under Yellowstone that we have to thank for all of that. An eruption in Yellowstone could be a global cataclysm, but NASA has a plan to reduce the risk while also generating power. The plan is not without risks, and the price tag is high. Still, if it keeps us from being wiped out by clouds of hot ash, it might be something to consider.
