US Approves World's Most Sensitive Dark Matter Detector To Begin Hunt In 2020

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

Newly discovered 'ghost galaxy' full of dark matter is as big as the Milky Way

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.

Much ado about nothing: Astronomers use empty space to study the universe

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.

World's most sensitive dark matter detector completes search

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.

Dark Matter May Be Made Up of Black Holes

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.

Scientists Have Finally Solved 50-Year-Old Mystery Of Bizarre Signals

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.

Second strongest shock wave found in merging galaxy clusters

Astronomers have discovered the second-strongest merger shock in clusters of galaxies ever observed.

The Universe is expanding faster than the laws of physics can explain, new measurements reveal

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.

Black holes banish matter into cosmic voids

Using a computer simulation, astronomers probe the ‘cosmic web’ of the universe, its honeycomb-like structure on the largest scales.

Galaxy clusters are way more complicated than we thought

Galaxy clusters are groupings of hundreds to thousands of galaxies bound together by gravity, and are the most massive structures found in the universe.

New theory of secondary inflation expands options for avoiding an excess of dark matter

A new theory suggests a shorter secondary inflationary period that could account for the amount of dark matter estimated to exist throughout the cosmos.

China's Dark Matter Satellite Sends Back First Data

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.

Finally some answers on dark energy, the mysterious master of the Universe

The world's fourth-largest optical telescope has a new experiment coming online.

When dark energy turned on (Update)

(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.
