Evidence of dark matter-free dwarf galaxy challenges conventional galaxy formation models
Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have found compelling evidence of a dark matter-deficient dwarf galaxy, FCC 224. This ultra-diffuse galaxy is located on the ...
Two projects in JWST’s first observation cycle will probe the nature of dark matter. On Christmas morning of 2021, an Ariane 5 CEA rocket blasted off from Kourou, French Guiana. It carried with it the ...
Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could have ...

'The models were right!' Astronomers locate universe's 'missing' matter in the largest cosmic structures
Astronomers have discovered a vast tendril of hot gas linking four galaxy clusters and stretching out for 23 million light-years, 230 times the length of our galaxy. With 10 times the mass of the ...
This image shows the new filament, which connects four galaxy clusters: two on one end, two on the other. These clusters are visible as bright spots at the bottom and top of the filament (four white ...
Physicists have unveiled a new way to simulate a mysterious form of dark matter that can collide with itself but not with normal matter. This self-interacting dark matter may trigger a dramatic ...
