Ceres in Color

Great look at Ceres, click the image to see a larger version. This view of Ceres, produced by the German Aerospace Center in Berlin, combines images taken during Dawn’s first science orbit in 2015 using the framing camera’s red, green and blue spectral filters. The color was calculated using a reflectance spectrum, which is based […]

Mystery Spots on Ceres

A nice look at some of those mysterious white spots on Ceres. The area shown above is some of the brightest on the dwarf planet. From the Dawn vantage point of just 385 km / 240 miles scientists believe the white material is some of salt. Looking in the center of the image at the […]

Landscape of Ceres

Here’s a view of the southern mid-latitude region of Ceres around what is known as the Gerber Catena.  There is a nice 3-D version of this image you can see at NASA  (click your browser’s BACK button to return) . Apparently there are grooves on Ceres caused by tectonic activity on the (dwarf) planet. The […]
