On May 19, 2005, NASA's Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars. This Panoramic Camera mosaic was taken around 6:07 in the evening of the rover's 489th Martian day, or sol.
Based on new evidence from Jupiters moon Europa, astronomers hypothesize that chloride salts bubble up from the icy moons global liquid ocean and reach the frozen surface where they are bombarded with sulfur from volcanoes on Jupiters moon Io. credit : NASA/JPL-CalTech
Central area of the Milky Way galaxy, released by astronomers at the European Southern Observatory's Paranal Observatory in Chile. The photo shows 84 million stars in an image measuring 108,500×81,500, which contains nearly 9 billion pixels, and is actually a composite of thousands of individual photographs shot with the observatory's VISTA survey telescope.
Osmium twinning / Osmium is a hard, brittle, blue-gray or blue-black transition metal in the platinum family and is the densest naturally occurring element, with a density of 22.59 g/cm3 (slightly greater than that of iridium and twice that of lead).
This is a deep image of the Sword of Orion - the three stars that make up the weapon hanging off the belt of this famous celestial hunter. The image showcases the amazing mix of physical and optical processes including atomic emission, Rayleigh scattering, reflection and absorbtion of light, that go on in this star forming region to create this kaleidescope of colours and details.
Gale Carter, Mars - Curiosity Rover's New Home: The dark patches at the top of this frame show the southeastern edge of Mt. Sharp; the floor of Gale Crater occupies the remainder of the image. Small hills dotted with rocks and debris populate Mt. Sharp’s margin, implying that the constituent rock is easily eroded by wind scouring the hillside. by Jeffrey Marlow, wired.com.
