Please sir, an extra helping of "crystal mush."
The surface of Venus is covered in hundred-meter volcanic mountains made of crystals, and scientists think they finally figured out how they formed.
The crystals, which form as mushy liquid deep underground and get squeezed through the surface, resemble tiny crystalline structures found here on Earth in Cyprus, New Scientist reports. Scientists from the University of Edinburgh suspect that these crystals are able to reach the surface and form mountains as the result of tectonic activity, and they hope that future missions to our planetary neighbor will be able to investigate further.
The idea is that the crystals form underground through the same process as lava, except it ends up being thicker and mushier. So when a volcano erupts, the crystals get left behind in large deposits that accumulate and eventually press out through the surface, according to research published in the journal Icarus — like a magnificent, sparkly pimple.
While magma flows away, the crystals stick together to form tall, steep structures on the planet's surface.
"If you poured olive oil onto the table it would just flow away and run all over the table and you’d still have a flat surface," Edinburgh researcher Geoffrey Bromily told New Scientist, illustrating the differences between the volcanoes. "If you poured something a lot thicker, like peanut butter, that would stay there and form a dome on the table."
