3-mile high ‘pyramid peak’ spotted on mysterious Ceres dwarf planet
The mystery of bright spots of the dwarf planet Ceres continues to thicken: New photographs captured by the Dawn probe have shown a three-mile high pyramid shaped peak, but also giving updated photos of the of dwarf planet’s confusing bright spots. NASA’s Dawn spacecraft took the photos on June 9 from a distance of 2,700 miles (4,300 kilometers). It exposed a number of new geographical features, in particular, the high peak that juts out from the surrounding site. Carol Raymond, deputy chief investigator for the Dawn mission, centered at NASA's Jet Propulsion Laboratory in California, said “The surface of Ceres has exposed many fascinating and unique geographies. For instance, icy moons in the outer solar system have craters with central pits, but on Ceres central pits in large craters are much more common. These and other features will allow us to understand the inner structure of Ceres that we cannot sense directly,”

NASA’s Dawn spacecraft has been circling the Ceres dwarf planet since March 6, which is located in the asteroid belt between Mars and Jupiter. The new pictures also helped to shed some light on the planets bright spots, which are situated in a crater, which is nearly 55 miles in length. Dawn chief investigator Chris Russell of the University of California, Los Angeles said in a report last week. “The bright spots in this configuration make Ceres unique from anything we’ve seen before in the solar system. The science team is working to understand their source,” Dawn will carry on its mission on current altitude till June 30 and will continue to take pictures of Ceres. Though, it will then descend to an altitude of 900 miles (1.450 kilometers) in early August.
On April 13, pictures were released from the NASA probe, which first disclosed two bright spots, which have been confusing scientists. On visible light images taken earlier, the two irregular spots appear bright white, leading to theories about so-called cryovolcanoes. But the newly-issued infrared photographs show that the spots have totally contradictory thermal properties. Researchers are still not certain if the spots are water, ice, or “hydrated minerals,” but they can say for sure that unchanging ice would be problematic so close to the sun.
