Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to ...

New simulations suggest that dozens of ultra-faint “ghost” galaxies may be orbiting the Milky Way, hidden from current ...

The Milky Way could have many more satellite galaxies than scientists have previously been able to predict or observe, ...

Brown dwarfs, also known as "failed stars," could be corrupted by dark matter and transformed into "dark dwarfs" powered by ...

Tony Tyson’s cameras revealed the universe’s dark contents. Now, with the Rubin Observatory’s 3.2-billion-pixel camera, he’s ...

How dark matter in galaxies is distributed Date: October 28, 2020 Source: Instituto de Astrofísica de Canarias (IAC) Summary: Scientists have shown that the dark matter in galaxies follows a ...

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).

This composite image shows the distribution of dark matter, galaxies and hot gas in the core of the merging galaxy cluster Abell 520, formed from a violent collision of massive galaxy clusters.

Analysis of this data has allowed scientists to observe some strange phenomena in Abell 2744, including a pocket of dark matter with no gas or galaxies, and a clump of galaxies with no associated gas.

Simulations suggest that gravity draws dark matter into a web of filaments, and galaxy formation occurs primarily at the sites where these filaments meet. This explains why most galaxies we see ...

Diagram shows the mass of dark matter haloes around quasars at the heart of ancient active galaxies. (Image credit: Arita et al. CC BY) The nature of dark matter is a pressing problem for science ...

The galaxy appears to have no dark matter—a new, puzzling piece of data for astrophysicists. Astronomer Pieter van Dokkum and colleagues wanted to know more about how these huge, ...
