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 ...

The nearby dwarf galaxy Segue 1 is exceptionally faint for its mass, which has puzzled astronomers almost since its discovery. A new paper proposes this could be because it hosts a ridiculously ...

About 50 tiny galaxies surround our home galaxy, the Milky Way. New research suggests that one of them, known as Crater II, may consist of dark matter particles that interact with each other. | Credit ...

New simulations suggest dark matter could explain the mysterious gamma-ray glow at the Milky Way’s center. The findings show that the galaxy’s early mergers may have shaped dark matter in a way that ...

Astronomers have unveiled a new catalog of massive galaxy clusters, revealing new insight on the evolution of the universe ...

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 astronomers better ...

The swirling vortex center of the Milky Way is a weird place, with a supermassive black hole that vacuums up interstellar matter and supernovae torpedoing hapless stars to the edges of our galaxy. Add ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

Researchers have identified a high-velocity cloud (HVC) component, designated AC G185.0-11.5, within the AC-I Complex near the Milky Way, exhibiting rotational characteristics consistent with a ...

A new image from the Hubble Space Telescope shows a galaxy partly hidden by a huge cloud of dust known as a dark nebula. The galaxy IC 4633 still shines brightly and beautifully in the main part of ...
