A few days before their arrival at Ceres NASA probe Dawn has once again received much more detailed images of the dwarf planet. They show that the mysterious bright spot probably consists of two separate structures.

The bright spot on the dwarf planet Ceres apparently consists of two separate structures, possibly volcanic origin. The lay the latest photos of Dawn close, made ​​just days before the arrival of the NASA probe to the celestial bodies, writes the US space agency . The reach of approximately 46,000 kilometers and are expected to be sufficiently detailed than the already increasingly fierce pictures of the past weeks and months. In addition to the spots they show some large craters that cover Ceres everywhere.

Dawn to swivel on 6 March in orbit around Ceres and explore the celestial body after extensively. Want to investigate, the researchers its origin and development, but of course the light structure that draws attention to itself for weeks. Although the stains are still too small to be resolved by the imager sufficient simultaneously but they are brighter than anything else in Ceres. That was really surprising and scientists still a mystery, says Andreas Nathues from the Max Planck Institute for Solar System Research in Göttingen. He leads the team that researches with the camera on Dawn.

The NASA probe was launched in September 2007 and had first approached the asteroid Vesta and researched extensively. With 525 kilometers in diameter Vesta is the second largest object in the asteroid belt. Overall, they made ​​it more than 30,000 photos and sent a lot of other research results to Earth. Powered by ion engines we continued towards Ceres, the largest with about 950 kilometers in diameter object in the asteroid belt. The two celestial bodies are the largest objects in the area between Mars and Jupiter.
