Now, sure, these volcanoes are really only maybe-volcanoes, because Pluto is, like, really far away, man. And so it’s hard to tell exactly what’s going on. If they are volcanoes, they won’t be spewing magma or lava bombs. These would be cryovolcanoes. Ice vulcanism! The New Horizons team thinks that these structures could have formed when a slurry of water ice, nitrogen, ammonia, or methane erupted from beneath the dwarf planet’s surface. The One Ring wouldn’t dissolve into steaming fizz; it’d freeze and crackle into shards. Which would be cool. Whatever works, right?
