Ice volcano Ahuna Mons discovered on Ceres

NASA's Dawn spacecraft has identified what appears to be an ice volcano on the dwarf planet's surface.
The largest object in the asteroid belt between Mars and Jupiter, Ceres has been the subject of much intrigue recently thanks to its mysterious bright spots and anomalous surface features.

Now scientists have identified what they believe to be evidence of cryovolcanism there as well in the form of a large volcano formed millions of years ago by briny 'lava' flowing up from far below.
Cryovolcanoes, which are produced through processes involving freezing liquids or gases rather than molten rock, have long been suspected on several icy worlds in our solar system including Saturn's moon Titan and the distant world of Pluto which was also visited just last year.

"Ahuna Mons is evidence of an unusual type of volcanism, involving salty water and mud, at work on Ceres," said NASA's Ottaviano Ruesch. "Geologic activity was discussed and debated among scientists: now we finally have observations testifying to its occurrence."

Very cool!   The writers of "The Expanse" can now justify themselves for having Ceres mined for ice to ship water to Earth and Mars.

Why is the hole next to the mountain about the same volume. I don't think it is what they say it is.

What do you think it is ?

Some kind of alien mining operation, probably old.

Yeah that is much more likely than a cryo volcano.
