Cryovolcano is a cool word, literally and figuratively. You hear about it a lot when talking about solar system moons like Enceladus, and it’s one of those words that would make a heck of a great Hollywood disaster movie title, like ‘Sharknado’ or ‘Armageddon.’ I do not, however, endorse either of those movies, they were both terrible. At any rate, a real cryovolcano seems like an interesting thing. It’s a volcano in the sense that it looks a little like a mountain and spews out material when the pressure builds from beneath the surface, but it’s not your traditional Earth-like volcano...
Since the arrival of the Dawn spacecraft in March of 2015, we have seen tremendous views of the dwarf planet Ceres. Lying within the asteroid belt, it is revealed to be a frozen world of ice and rock, with many interesting features. None of these features had generated more intrigue than the famous bright spot in the bottom of what is now called the Occator crater. The icy spot has had astronomers guessing for months whether it is a cryovolcano, water ice, frozen carbon dioxide, or something even more strange and rare. As the Dawn spacecraft has moved into a...
The short answer is….we don’t know. It could still be a lot of different things, but take a look for yourself and see if you can figure it out. Here are the possibilities: Ceres is soon to make a descent to its lowest orbit for final mapping, and will be orbiting only 375 Km above the surface. This will give the highest resolution data yet, and hopefully shed some light on the mystery of Occator crater. What do you think?
