This is the newest image of the main bright spots on dwarf planet Ceres taken by the Dawn spacecraft. It was taken on May 16, 2015, with a resolution of 700 metres (2,250 feet) per pixel. The second spot on the right can now be seen to be several smaller spots close together.
Some new views of Ceres were released today from the Dawn spacecraft, which include the now-famous mystery bright spots, as well as some new spots not seen before. The most prominent “double spot” as previously viewed, can now be seen to be multiple spots of various sizes.
The Dawn spacecraft has almost reached the dwarf planet Ceres, and a lot more detail can be seen as it gets closer. The odd bright spots which have puzzled scientists for a long time now can also be seen more clearly for the first time. What was thought to be one spot in this crater is now obviously two close together. Are they exposed ice or some other material? Are they related to possible cryovolcanoes? Dawn was 46,000 kilometers (29,000 miles) away when it took this image on February 18, 2015.
The Dawn spacecraft left behind the giant asteroid Vesta last September, and is now en route to the even bigger dwarf planet Ceres, but scientists are still busy studying all of the data that was sent back to Earth while it was orbiting Vesta for over a year. And as often happens while exploring these new worlds, they have made a surprising discovery: long, sinuous gullies on the walls of geologically younger craters.
With all of the news lately about the landing of the Curiosity rover on Mars, it might be easy to forget about the other missions …
