Dark energy, the mysterious phenomenon that powers the expansion of the universe, may undergo periodic 'violent transitions' ...

Dark matter continues to confound us, so far defying every attempt to decipher it. According to a new study, clues may lurk ...

Rolf Landauer showed that "information is physical" with every bit equivalent to a small amount of energy proportional to ...

NSF NOIRLab rings in the New Year with a glittering galaxyscape captured with the Department of Energy ... thousands of galaxy clusters, unlocking clues to the distribution of dark matter around ...

Scientists used XRISM to detect hot gas flows in Centaurus Cluster, proving that galaxy collisions cause gas movement and ...

XRISM has uncovered how galaxy clusters evolve—violent mergers create turbulence, preventing hot gas from cooling. This ...

we can look at how light is bent around large galaxies to try to understand what role dark energy played on the growth of structures, such as large galaxy clusters, in the universe. We can also plot ...

Data from the XRISM X-ray satellite provide unprecedented detail on how ionized plasma moves in massive galaxy clusters — a question with huge cosmological and astrophysical implications.

It centres around the mysterious force known as "dark energy." This concept emerged ... enormous filaments and walls filled with galaxies and galaxy clusters. And in between those filaments ...

Data from the former ROSAT X-ray satellite have revealed a network of 68 galaxy clusters in the nearby universe, stretching over 1.4 billion light-years. Averaged over very large volumes, the universe ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. Dark energy ...

A mysterious phenomenon at the center of our galaxy could be the result of a different type of dark matter.
