Their study, published in Nature, poses new challenges to the prevailing galaxy formation models within the Λ-Cold Dark Matter (ΛCDM) framework. Historically, massive galaxies have served as the ...

A new study of diffuse dwarf galaxies is challenging the prevailing galaxy formation model within the standard Cold Dark Matter (CDM) framework, leading to a proposed new model of dark matter.

It shows a rotational structure but no visible stars. This characteristic aligns with the hypothesis of a dark galaxy, primarily composed of dark matter. Measurements indicate that unexplained matter ...

In the wake of bombshell findings that suggest dark energy might be weakening as the universe expands, physicists are considering replacing the standard cosmological model of the universe with ...

They conclude by noting that G185.0–11.5 is close enough for study by other ground-based telescopes, which means that if it is a dark galaxy, further scrutiny could soon prove it. More ...

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 ...

A potential dark galaxy — one made primarily of dark matter — may have been spotted in the local universe. Dark galaxies are theoretical, starless systems whose discovery could help ...

Be careful out there, astronomers: There could be a dark galaxy in our midst. In research published today in Science Advances, researchers from the Chinese National Academy of Sciences discovered ...

Astronomers may have just stumbled across a ghost galaxy hiding in plain sight — a small, starless, fast-moving cloud of gas that checks all the boxes for what’s known as a “dark galaxy.” ...

A new discovery by NASA's flagship James Webb Space Telescope has pushed forward the confirmed end date of the so-called "Cosmic Dark Ages" by ... analyzed the distant galaxy JADES-GS-z13-1 ...

Scientists have just made an incredible discovery—a possible dark matter star right in our own galaxy! Unlike normal stars, this one might be powered by mysterious dark matter instead of nuclear ...
