Those "dark atoms" might radically alter the evolution of galaxies and the formation of stars, giving astronomers a new opportunity to understand this mysterious substance.. Dark matter makes up ...

Hubble's new image of galaxy cluster Abell 209 reveals over 100 galaxies and gravitational lensing effects from dark matter ...

"Dark matter could be captured by stars and accumulate inside them. If that happens, it might also interact with itself and ...

P. van Dokkum et al/Nature 2022 Two galaxies found to be free of dark matter, NGC 1052-DF2 and NGC 1052-DF4, are part of a line of 11 galaxies total (shown in insets).

An ultradiffuse galaxy’s dark matter halo reaches much further out than that of a regular dwarf galaxy, which shouldn’t happen with the collisionless particles proposed by CDM—particles that ...

“We were really surprised to find a galaxy without dark matter in 2018. Finding a second one in 2019 was super odd, and we had no explanation,” van Dokkum says. “Now we think we are seeing ...

Scientists have shown that the dark matter in galaxies follows a 'maximum entropy' distribution, which sheds light on its nature. Skip to main content. Your source for the latest research news.

The earliest galaxies are thought to have formed as the gravitational pull of dark matter, which has been impossible to study directly, slowly drew in enough hydrogen and helium to ignite stars.

Two giant clusters of galaxies observed in the process of colliding are going so hard that their dark matter has basically detached from normal matter and flown ahead. It's like untethered cargo ...

We know that this dark universe must exist because of the movements of galaxies, but we can’t see it and can’t touch it. You might think that would make researching dark matter next to ...

A composite of Stephan’s Quintet, a visual grouping of five galaxies, constructed from almost 1,000 separate image files from the James Webb Space Telescope. UCLA astrophysicists believe if cold ...
