Ceres Spots Continue to Mystify in Latest Dawn Images

Dawn has been studying the dwarf planet in detail from its second mapping orbit, which is 4,400 kilometers above Ceres. A new view of its intriguing bright spots, located in a crater about 90 kilometers across, shows even more small spots in the crater than were previously visible.
At least eight spots can be seen next to the largest bright area, which scientists think is approximately 9 kilometers wide. A highly reflective material is responsible for these spots -- ice and salt are leading possibilities, but scientists are considering other options, too.

Dawn probe sees Ceres' spots in more detail

Nasa's Dawn probe has just retuned the image - one of the first snapshots to come down from the satellite since getting into its latest mapping orbit, which is now just 4,000km above the surface.
Mission scientists confess still to being puzzled by the features.

Best view yet of Ceres' spots

The fascinating bright spots on the surface of the dwarf planet Ceres have come into sharper view.
What were initially thought to be just a couple of brilliant, closely spaced features at one location now turn out to be a clutch of many smaller dots.

Dwarf Ceres captured in colour

The US space agency's (Nasa) Dawn mission to Ceres has released its first colour map of the dwarf planet.
The colours illustrate variations in surface materials, hinting at the diverse processes that have helped shape this 950km-wide body.

Bright spots on Ceres could be water volcanoes

As NASA's Dawn spacecraft pulled into orbit earlier this month around the dwarf planet Ceres in the asteroid belt, it spotted a mysterious bright spot inside a crater. There were suspicions that the spot could be caused by water spewing into space, now fresh views, presented for the first time yesterday, lend weight to the idea.
