New Clues to Ceres' Bright Spots and Origins 9 December 2015, by Elizabeth Landau
New clues to Ceres' bright spots and origins 9 December 2015, by Elizabeth Landau they say. "The global nature of Ceres' bright spots suggests that this world has a subsurface layer that contains briny water-ice," Nathues said. A New Look at Occator The surface of Ceres, whose average diameter is 584 miles (940 kilometers), is generally dark—similar in brightness to fresh asphalt—study authors wrote. The bright patches that pepper the surface represent a large range of brightness, with This representation of Ceres' Occator Crater in false the brightest areas reflecting about 50 percent of colors shows differences in the surface composition. sunlight shining on the area. But there has not been Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA unambiguous detection of water ice on Ceres; higher-resolution data are needed to settle this question.

Dark streaks, In one study, scientists identify this bright material possibly fractures, traverse the pit. Remnants of a as a kind of salt.

Re Going to Fly Around the Dwarf Planet Ceres
Buckle Up – We’re going to fly around the dwarf planet Ceres By Mark Young, SouthFloridaReporter.com Managing Editor, Aug 7, 2015 – Fasten your seatbelts and place your seat backs in the upright position, we’re about to fly around the dwarf planet Ceres. Courtesy of NASA. In this dramatic 3-D video you will fly over the mountains and craters, pausing every so often as Marc Rayman, Dawn Mission Director, describes the scenes below you. Here’s more information from NASA: Striking 3-D detail highlights a towering mountain, the brightest spots and other features on dwarf planet Ceres in a new video from NASA’s Dawn mission. A prominent mountain with bright streaks on its steep slopes is especially fascinating to scientists. The peak’s shape has been likened to a cone or a pyramid. It appears to be about 4 miles (6 kilometers) high, with respect to the surface around it, according to the latest estimates. This means the mountain has about the same elevation as Mount McKinley in Denali National Park, Alaska, the highest point in North America. Among the highest features seen on Ceres so far is a mountain about 4 miles (6 kilometers) high, which is roughly the elevation of Mount McKinley in Alaska’s Denali National Park. Credits: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA/LPI “This mountain is among the tallest features we’ve seen on Ceres to date,” said Dawn science team member Paul Schenk, a geologist at the Lunar and Planetary Institute, Houston. “It’s unusual that it’s not associated with a crater. -

More than 12 billion miles away a tiny spaceship is leaving our Solar System and entering the void of deep space - the first human-made object ever to do so. Slowly dying within its heart is a nuclear generator that will beat for perhaps another decade before the lights on Voyager finally go out. But this little craft will travel on for millions of years, carrying a Golden Record bearing recordings and images of life on Earth. In all likelihood Voyager will outlive humanity. THE FARTHEST will celebrate these magnificent machines, the men and women who built them and the vision that propelled them farther than anyone could ever have hoped.

Nustar Finds New Clues to 'Chameleon Supernova' 25 January 2017, by Elizabeth Landau
NuSTAR finds new clues to 'chameleon supernova' 25 January 2017, by Elizabeth Landau 2014C dramatically changed in appearance over the course of a year, apparently because it had thrown off a lot of material late in its life. This doesn't fit into any recognized category of how a stellar explosion should happen. To explain it, scientists must reconsider established ideas about how massive stars live out their lives before exploding. "This 'chameleon supernova' may represent a new mechanism of how massive stars deliver elements created in their cores to the rest of the universe," said Raffaella Margutti, assistant professor of physics and astronomy at Northwestern University in Evanston, Illinois. Margutti led a study about supernova SN 2014C published this week in the Astrophysical Journal. A supernova mystery Astronomers classify exploding stars based on whether or not hydrogen is present in the event. This visible-light image from the Sloan Digital Sky While stars begin their lives with hydrogen fusing Survey shows spiral galaxy NGC 7331, center, where into helium, large stars nearing a supernova death astronomers observed the unusual supernova SN have run out of hydrogen as fuel.

Those that do have an abundance of before the supernova explosion (left) and after it (right). hydrogen, which are rarer, are called "Type II." Red, green and blue colors are used for low, medium and high-energy X-rays, respectively.
