Let’s Play Travian Together
- Galactic Building Blocks December 30, 2009The current view of galactic formation is that galaxies form from a "bottom-up" method. In this picture, small dwarf galaxies, full of metal poor stars, were attracted by dark matter halos in the early universe which merged into larger galaxies. Many of those metal poor stars can still be seen today in the halo of [...]Jon Voisey
- Where To Next for NASA's Solar System Exploration? December 29, 2009Where is NASA going next to probe our solar system? The space agency announced today they have selected three proposals as candidates for the agency's next space venture to another celestial body in our solar system. The proposed missions would probe the atmosphere and crust of Venus; return a piece of a near-Earth [...]Nancy Atkinson
- New Horizons Spacecraft Now Closer to Pluto Than Earth December 29, 2009The New Horizons spacecraft crossed a milestone boundary today: it is now closer to its primary destination, Pluto, than to Earth. But New Horizons –the fastest man-made object — is not yet halfway to the dwarf planet. That won't happen until February 25, 2010. New Horizons is now 1,440 days [...]Nancy Atkinson

December 29, 2009We are not quite at that point where you can ask your computer to swing over to the Orion Nebula and take a few shots for next weeks’ astrophotography competition – oh and a cup of Earl Grey, hot, thanks. But every day seems to get us that little bit closer.(...)Read the rest of Wolfram Alpha [...]Steve Nerlich
- An Exotic Source for Cosmic Rays: 'Baby' Black Holes December 28, 2009Cosmic rays – particles that have been accelerated to near the speed of light – stream out from our Sun all of the time, though they are positively sluggish compared to what are called Ultra-High-Energy Cosmic Rays (UHECRs). These types of cosmic rays originate from sources outside of the Solar System, and are much more [...]Nicholos Wethington
- Stately Saturn December 29, 2009Saturn, stately and resplendent in this natural color view, dwarfs its icy moon Rhea. Rhea (949 miles in diameter) orbits beyond the rings on the right of the image. The moon Tethys is not shown here, but its shadow is visible on the planet on the left of the image. This view looks toward the northern, sunlit side of the rings from just above the ringplane. […]
