EUROPE : NASA has released a set of colourful maps of dwarf planet Ceres created using photographs taken by its Dawn spacecraft.
Based on the details received from Dawn, NASA scientists say that the height difference crater bottoms and mountain peaks as great as 9 miles (15 kilometers).
Some of the craters have been officially named with names inspired by spirits and deities relating to agriculture from a variety of cultures. The International Astronomical Union recently approved a batch of names for features on Ceres.
Occator, the mysterious crater containing Ceres’ brightest spots, has a diameter of about 60 miles (90 kilometers) and a depth of about 2 miles (4 kilometers). The crater has been named after Occator – the Roman agriculture deity of harrowing, a method of leveling soil.
There is this smaller crater with bright material, which was previously called “Spot 1″. It has now been identified as Haulani, after the Hawaiian plant goddess. This crater has a diameter of about 20 miles (30 kilometers) – third of that of Occator. The surprising bit about this crater is that it seems to be colder than most of the territory around it – based on the temperature data from Dawn’s visible and infrared mapping spectrometer.
