NASA spies 3-mile-tall 'pyramid,' more bright spots on Ceres [1]

Ancient astronaut alert! More weird features have been spotted by NASA's Dawn spacecraft on Ceres, a dwarf planet and the largest object in the asteroid belt between Mars and Jupiter.

As Dawn first made its approach on Ceres [2] earlier this year, it caught sight of large, bright and mysterious reflective spots in a crater on the big rock, which is also believed to contain quite a bit of water [3], ice and/or mud in its interior.

Now orbiting at a near altitude of just 2,700 miles, those big spots remain a mystery (the leading guess [4] is still reflective patches of ice or salts), but Dawn is also beginning to pick out other bright spots and an odd pyramid-shaped peak that NASA estimates to be three miles tall, which would put it higher than any of the Rocky Mountains. The image with the peak [5] was taken on June 6 and released Wednesday.
