NASA’s mission to that other dwarf planet, Ceres, has delivered a fresh bird’s-eye view of one of the asteroid’s most mysterious features: a cone-shaped, 4-mile-high “pyramid” mountain whose sides are covered with bright material.
The Dawn mission’s principal investigator says those shiny sides may be connected to Ceres’ other big mystery: the bright spots that shine out from the mini-world’s dark surface.
“The bright material on the mountain and in the bright spots are probably the same material,” UCLA’s Christopher Russell told GeekWire in an email. “How the material got on the sides of the mountain and also in the bottom of the craters is unknown.”
Which begs the question: What is that stuff?
