Dark matter even darker than once thought
Astronomers have studied how dark matter in clusters of galaxies behaves when the clusters collide. The results show that dark matter interacts with itself even less than previously thought, and narrows down the options for what this mysterious substance might be.

Best view yet of dusty cloud passing galactic center black hole
The best observations so far of the dusty gas cloud G2 confirm that it made its closest approach to the supermassive black hole at the centre of the Milky Way in May 2014 and has survived the experience. The new result shows that the object appears not to have been significantly stretched. It is most likely to be a young star with a massive core that is still accreting material.

Ancient Martian lake system records two water-related events
Researchers have completed a new analysis of an ancient Martian lake system in Jezero Crater, near the planet's equator. The study finds that the onslaught of water that filled the crater was one of at least two separate periods of water activity in the region surrounding Jezero.

The two-year mission of the one-ton rover is to find out if Mars is, or was, capable of supporting life., Fri, 27 Mar 2015 11:49:14 GMT

Dark matter is darker than once thought
This panel of images represents a study of 72 colliding galaxy clusters conducted by a team of astronomers using NASA's Chandra X-ray Observatory and Hubble Space Telescope. The research sets new limits on how dark matter - the mysterious substance that makes up most of the matter in the Universe - interacts with itself, as reported in this article. This information could help scientists narrow down the possibilities of what dark matter may be. Astronomy & Space News, Fri, 27 Mar 2015 11:49:14 GMT

Video: NASA Mercury mission may hold clues to Earth's origins and evolution
Sean Solomon, director of Columbia University's Lamont-Doherty Earth Observatory, has been leading NASA's MESSENGER mission to Mercury for the last four years. MESSENGER is the first spacecraft to orbit Mercury. Astronomy & Space News, Fri, 27 Mar 2015 11:49:14 GMT

NASA asteroid hunter spacecraft data available to public
Millions of images of celestial objects, including asteroids, observed by NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft now are available online to the public. The data was collected following the restart of the asteroid-seeking spacecraft in December 2013 after a lengthy hibernation. Astronomy & Space News, Fri, 27 Mar 2015 11:49:14 GMT

Astronomers identify the best supernovae for measuring cosmic distances
The brilliant explosions of dead stars have been used for years to illuminate the far-flung reaches of our cosmos. The explosions, called Type Ia supernovae, allow astronomers to measure the distances to galaxies and measure the ever-increasing rate at which our universe is stretching apart.
