Demoted planet Pluto may have an ice volcano on its surface the size of Yellowstone, scientists recently discovered.
The newly discovered volcano, Kiladze Caldera, was originally pegged as a crater via images captured by NASA's New Horizons mission. After taking a second look at data from New Horizons, scientists now think Kiladze Caldera has erupted multiple times over its history, spewing around "a thousand kilometers of cryo-lava" — or enough to almost cover the city of Los Angeles — in each of its largest eruptions, the researchers wrote in a study submitted to the journal Icarus and published on the preprint database arXiv.
