Fermi space telescope expands its search for dark matter

14 August 2016 Astronomy Now

Dark matter, the mysterious substance that constitutes most of the material universe, remains as elusive as ever. Although experiments on the ground and in space have yet to find a trace of dark matter, six or more years of data from NASA’s Fermi Gamma-ray Space Telescope has broadened the mission’s dark matter hunt using some novel approaches.

World’s most powerful telescope digital camera gets green light for construction

1 September 2015 Astronomy Now

The U.S. Department of Energy has approved the start of construction for a 3.2-gigapixel digital camera — the world’s largest — at the heart of the Large Synoptic Survey Telescope (LSST). Assembled at the SLAC National Accelerator Laboratory, the camera will be the eye of LSST, revealing unprecedented details of the universe and helping unravel some of its greatest mysteries.

Dark energy survey finds eight more galactic neighbours

18 August 2015 Astronomy Now

Scientists on the Dark Energy Survey, using one of the world’s most powerful digital cameras, have discovered eight more faint celestial objects hovering near our Milky Way galaxy. Signs indicate that they, like the objects found by the same team earlier this year, are likely dwarf satellite galaxies — the smallest and closest known form of galaxies.
