Since NASA’s Dawn probe arrived in March at Ceres, a dwarf planet in our asteroid belt, it’s been seeing some strange stuff. Bright spots, mostly. But now it’s also found a pyramid-shaped protrusion—NASA describes it as “a mountain with steep slopes” in the middle of a “relatively smooth area” of the planet’s surface. And it’s huge—three miles tall, NASA says. You can see it in the image above, sticking out of the planet’s surface, like a giant pimple on a chin.

Naturally, all of humanity is taking all this very calmly.

But even NASA scientists aren’t sure what to make of all this. We should have more answers later in the summer, when Ceres creeps in closer to the planet.
