Earlier this month we discovered that Ceres’ pair of mysterious bright spots were, in fact, not two—they were many, many more. Now, we’ve got the closest look yet of the spots thanks to NASA’s Dawn mission.
This image, captured on May 16th, show a group of the brightest spots on the dwarf planet. Taken from a distance of 4,500 miles, each pixel represents 2,250 feet (0.4 miles). “Dawn scientists can now conclude that the intense brightness of these spots is due to the reflection of sunlight by highly reflective material on the surface, possibly ice,” said Christopher Russell, one of the Dawn mission researchers, recently. All that said, scientists still don’t really know what the spots are made of. We’re still going to need to get closer to find out. [NASA]
