Scientists working on the Cryogenic Rare Event Search with Superconducting Thermometers (CRESST) experiment may have recorded evidence of Weakly Interacting Massive Particles (WIMPs) – a crucial step towards solving the mystery of ‘dark matter’, a material thought to make up the huge majority of the matter in the universe, but which is extremely difficult to detect.
Every three hours, NASA’s Fermi Gamma-ray Space Telescope scans the entire sky and deepens its portrait of the high-energy universe. Every year, the satellite’s scientists reanalyze all of the data it has collected, exploiting updated analysis methods to tease out new sources. These relatively steady sources are in addition to the numerous transient events Fermi detects, such as gamma-ray bursts in the distant universe and flares from the sun.
Is now the third year of the Royal Observatory’s competition to uncover the best photographs of stars, planets, galaxies and more. They received nearly 800 entries from astronomers around the world – that’s nearly double the number they received last year!

A University of Toronto-led team of astronomers has observed extreme brightness changes on a nearby brown dwarf that may indicate a storm grander than any seen yet on a planet. Because old brown dwarfs and giant planets have similar atmospheres, this finding could shed new light on weather phenomena of extra-solar planets.
