An advanced dark matter detector that hopes to find a rare collision between a dark matter particle and normal matter has just been approved in the US
Dragonfly 44, as it has been named, is roughly the same size as our Milky Way but with far fewer stars. Rather, the galaxy appears to be composed largely of dark matter, which does not emit light or interact with electromagnetic radiation.
An international team of astronomers reports that they were able to achieve four times better precision in measurements of how the universe's visible matter is clustered together by studying the empty spaces in between.
The Large Underground Xenon (LUX) dark matter experiment, which operates beneath a mile of rock at the Sanford Underground Research Facility in the Black Hills of South Dakota, has completed its silent search for the missing matter of the universe.
Now, some astronomers are beginning to think that dark matter is actually made up of ancient black holes formed during the first second of our universe's existence.
Terrific planet-wide thunderstorms on alien worlds far from our own have generated detectable radio bursts. Other such signals have been emitted from the heart of our own galaxy, perhaps due to the destruction of dark matter.
Astronomers have discovered the second-strongest merger shock in clusters of galaxies ever observed.
The most precise measurement ever made of the current rate of expansion of the Universe has been achieved by physicists in the US, and there's a problem: the Universe is expanding 8 percent faster than our current laws of physics can explain.
Using a computer simulation, astronomers probe the ‘cosmic web’ of the universe, its honeycomb-like structure on the largest scales.
Galaxy clusters are groupings of hundreds to thousands of galaxies bound together by gravity, and are the most massive structures found in the universe.
A new theory suggests a shorter secondary inflationary period that could account for the amount of dark matter estimated to exist throughout the cosmos.
There's a new player in the hunt for dark matter: China's Dark Matter Particle Explore (DAMPE) satellite, which launched on December 17. Ground stations have just received the first data beamed back from DAMPE. With all systems fully operational, the satellite officially begins its three-year mission.
The physicist predicts densities of up to 1 billion times greater than normal.
The world's fourth-largest optical telescope has a new experiment coming online.
(PhysOrg.com) -- Some six billion light years distant, almost halfway from now back to the big bang, the universe was undergoing an elemental change. Held back until then by the mutual gravitational attraction of all the matter it contained, the universe had been expanding ever more slowly. Then, as matter spread out and its density decreased, dark energy took over and expansion began to accelerate.
