Pluto's Ice-Spewing 'Supervolcano': Evidence of a Subsurface Ocean?
Scientists analyzing data from NASA's New Horizons mission have discovered a potential ice volcano on Pluto called Kiladze Caldera, which may be the size of Yellowstone. The volcano is believed to have erupted multiple times, spewing cryo-lava made of ice, water, and gases. Kiladze Caldera is surrounded by water ice and shows evidence of ammonia mixed with the ice, suggesting the possibility of liquid cryo-lava. The origin of the water cryo-lava and the presence of a subsurface ocean on Pluto remain mysteries for future research.
