Ceres’ White Spots Multiply in Latest Dawn Photos
http://www.universetoday.com/120244/cere...wn-photos/
EXCERPT: We don’t know exactly what those mysterious white spots on Ceres are yet, but we’re getting closer to an explanation. Literally. The latest images from the Dawn spacecraft taken a mere 8,400 miles from the dwarf planet Ceres reveal that the pair of spots are comprised of even more spots. “Dawn scientists can now conclude that the intense brightness of these spots is due to the reflection of sunlight by highly reflective material on the surface, possibly ice,” said Christopher Russell, principal investigator for the Dawn mission from the University of California, Los Angeles....

Blue Sunset on Mars

EXCERPT: The Curiosity rover took this picture of the Martian sunset. The image was taken on 15 April 2015 from Gale Crater. The image was taken by the “left-eye” of Curiosity’s Mast Camera on the rovers 956th Martian day. The image has been processed to remove artifacts and was white-balanced. The image does a pretty good job of showing what we would see if we were on the planet and someday perhaps we will. The Martian atmosphere has fine particles of dust that allow blue light to penetrate the atmosphere than longer wavelengths like yellows and reds which are scattered. This is unlike we see here on Earth where the scattering effect is alomost the other way around. The effect is also more pronounced at sunset than at mid-day. So on Mars blue sunsets are the norm.....
