Funding approved for sensitive dark matter detector

8 May 2018 Astronomy Now

The U.S. Department of Energy has approved funding for construction of the most sensitive detector ever built, located in a Canadian mine a mile down, to search for evidence of weakly interacting massive particles, or WIMPs, a leading dark matter candidate.


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.


Possible signature of dark matter annihilation detected

29 March 2016 Astronomy Now

Atoms or their constituents account for a mere 4.9 percent of the universe. The rest is dark matter, so understanding this ubiquitous yet mysterious substance is a prime goal of modern astrophysics. By studying the spatial distribution of gamma-ray emission in the Milky Way, astronomers believe they have now identified a signature of dark matter annihilation.


Researchers propose a new model for dark matter

15 March 2016 Astronomy Now

Indisputable physical calculations state that approximately 27 percent of the universe is dark matter, but there are indications that we might never see it. Now researchers in Denmark turn this somehow depressing scenario into an advantage and propose a new model for what dark matter might be — and how to test it.
