The second spot is not quite as bright, but still weirdly reflective compared to the rest of the dwarf planet. The geological mystery keeps getting more interesting! » 2/25/15 7:40pm 2/25/15 7:40pm

The Complete History Of Ceres, The Planet (?) Between Mars And Jupiter

Over the last couple of weeks, the Dawn Spacecraft has been beaming back spectacular pictures of Ceres – a world, discovered more than a century before Pluto, about which we know very little. This is the story of its discovery, and humanity's impending visit to one of the last unexplored planetary bodies in the… » 2/23/15 11:00am 2/23/15 11:00am

This Is The Greatest View Of Dwarf Planet Ceres We Have Ever Seen

The Dawn spacecraft has done it: it is now taking the highest-resolution images of the dwarf planet Ceres that have ever been seen. Not only is this new image better than the historic Hubble Space Telescope image, but every new release will be better than the one before until it arrives in orbit this March. » 1/28/15 4:51pm 1/28/15 4:51pm

Dawn On Alternate Approach To Ceres After Cosmic Ray Hiccups Ion Drive

After 14 months at Vesta, the Dawn spacecraft swung around for its second mission target: Ceres. After a rogue cosmic ray jumbling the best laid plans in September, the spacecraft is in its approach phase to slip into orbit around Ceres on March 6, 2015 just a half-day behind schedule. » 12/31/14 2:41am 12/31/14 2:41am
