Slushies anyone? After years of research, scientists now hypothesize that giant dome-like formations that were first photographed by NASA’s New Horizons spacecraft in 2015 were recently active icy volcanoes, also known as cryovolcanoes.
Scientists guessed these cryovolcanoes expelled "slushy" ice water as opposed to molten lava. These formations could indicate that the interior of the giant space rock was warmer than previously thought, according to a study published in the journal Nature Communications on March 29.
Researchers believe there may be an insulating layer under Pluto’s surface, kind of like the insulation in a coffee mug that keeps the liquid hot - the same principle applies to Pluto.
