After extensive training and testing on large mock data created by supercomputer simulations, they then applied this new tool to actual data from Japan's Subaru Telescope and found that the mass distribution derived from...

A small team of astronomers have found a new way to 'see' the elusive dark matter haloes that surround galaxies, with a new technique 10 times more precise than the previous-best method...

Dark matter does not emit, absorb, or reflect light. It does not interact with any known particles. Its presence is known only through its gravitational pull on visible matter in space.

Chinese Academy of Sciences Headquarters This figure illustrates structure in the simulated universe, in a box 200 million light-years on each side. It is color coded, using black, green, yellow, pink and white to represent…...

National Science Foundation backs Rice-led effort to create science-aware artificial intelligence Rice University HOUSTON — (Sept. 18, 2019) — A Rice University scientist and his colleagues are booting their search...

For the first time ever, scientists have identified a galaxy, NGC1052-DF2, that seems to lack the presence of dark matter.  For decades, scientists have believed that dark matter is a major aspect of any galaxy, which makes...

Among the cosmic rays that normally immerse the Earth, scientists say there are too many high-energy positrons, the antimatter counterparts of electrons...

For the first time ever, scientists have captured an image of a dark matter bridge, confirming the theory that galaxies are held together by a cosmic web...

A new map of the universe, the most comprehensive to date, boldly goes where no map has gone before. Astrophysicists in France have crafted a 3D map that includes galaxies from across almost two billion light years and have...

ANN ARBOR, Mich.—Scientists have, for the first time, directly detected part of the invisible dark matter skeleton of the universe, where more than half of all matter is believed to reside. The discovery, led by a University...

Two satellites, formerly owned by the National Reconnaissance Office (who operate all of the US spy satellites), have been given to NASA for use. The satellites, which are approximately the same size as the Hubble Telescope,...

Analysis of data from the National Science Foundation- (NSF) funded 10-meter South Pole Telescope (SPT) in Antarctica provides new support for the most widely accepted explanation of dark energy, the source of the mysterious...

From Bishop Hill, such a short story that it is difficult to excerpt, and given the importance, and the continuation reference to the story I broke on WUWT, I don’t think he’ll mind if I repost in entirety...
