Astronomers have stumbled upon yet another ghostly galaxy that appears to be devoid of dark matter. Dark matter, the invisible substance astronomers believe dominates the universe, provides the ...

An international team of astronomers has discovered a new ghost galaxy, that does not contain dark matter. Dark Matter is the elusive substance that most astrophysicists believe makes up most of the ...

Every galaxy is thought to form at the center of a dark matter halo. Stars are formed when gravity within dark matter halos draws in gas, but astrophysicists don't know whether star-free dark ...

the central galaxy of the Perseus cluster. These two elements seem to be connected by a faint "bridge" of material. The structural backbone of this bridge is dark matter, the universe's most ...

Scientists haven’t been able to explain this paradox. These galaxies are also believed to be filled with dark matter, making them excellent targets of study if scientists are to understand this ...

Comparison between a conventional galaxy (ESO 325-G004) enveloped in a halo of dark matter, occupying the heaviest plate on the weight scale, and the galaxy NGC 1277 (on the left), in which the ...

"The whole purpose of Euclid is really to put those two together to understand the nature of dark matter and dark ... sample ...

Astronomers have stumbled upon yet another ghostly galaxy that appears to be devoid of dark matter. First spotted in 2024, FCC 224 is a dwarf galaxy that boasts a dozen luminous, tightly bound ...

Get Instant Summarized Text (Gist) Dark matter halos are regions of gravitationally bound matter thought to form the centers of galaxies. The mass threshold below which these halos fail to form ...

Previous research found that the two galaxies in the NGC 1052 group, DF2 and DF4, belong to a trail of seven to 11 dark-matter-deficient galaxies that formed in the same ancient collision. FCC 224 ...
