But DF2 defies this idea. Van Dokkum and his colleagues were first drawn to the strange galaxy by a collection of 10 unusually bright compact objects orbiting around it.

Instead of some elusive quirk of dark matter causing Abell 3827’s uniquely hazy and askew gravitationally lensed images of a background galaxy, the researchers argue that the real culprit is the ...

Creating their own model of galaxy formation that took this into account, the team found the same early dark energy ingredient that seemed to relieve the Hubble tension also suggested the ...

Instead of looking at the large, bright galaxies that emit the most light, we'd want to scour the diffuse outskirts of galaxy groups and clusters for low-mass, low-surface-brightness galaxies.

SANTA CRUZ, CA — According to the prevailing “cold dark matter” theory of the evolution of the universe, every galaxy is surrounded by a halo of dark matter that can only be detected ...

Dark matter might not be totally dark: A new study reports that if dark matter has even a small interaction with particles of light, it could create a visible glow around galaxies. Searching for ...

Because dark matter is impossible to study directly, searching for bright patches of galaxies in the early universe could offer an effective test for theories about dark matter, which has been ...

According to the prevailing “cold dark matter” theory of the evolution of the universe, every galaxy is surrounded by a halo of dark matter that can only be detected indirectly by observing its ...

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.
