Scientists observing the Centaurus galaxy cluster made an exciting breakthrough by discovering powerful streams of hot gas ...

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

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

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 ...

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 ...

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 ...

But scientists are confident it exists because of the gravitational effects it appears to have on galaxies and galaxy clusters ... which we are accustomed. Dark energy is even more mysterious ...

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 ...

A mysterious phenomenon at the center of our galaxy could ... roiling source of energy doing just that, and our data says it might come from a much lighter form of dark matter than current models ...

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 ...
