A strange line of dwarf galaxies may have been the result of a bullet-like cosmic collision. Michael Keim at Yale University and his colleagues used the Keck Observatory in Hawaii to study a unique ...

The newly-discovered GS-NDG-9422 galaxy appears as a faint blur in this James Webb Space Telescope NIRCam (Near-Infrared Camera) image. It could help astronomers better understand galaxy evolution in ...

Dark matter doesn’t emit, absorb, or reflect light. It’s invisible but supposedly makes up 85% of the universe’s mass.

A "totally new phenomenon" has been discovered by astronomers in a strange galaxy from the dawn of time. This galaxy, named GS-NDG-9422 (9422), was discovered by the James Webb Space Telescope to have ...

The discovery of a 'weird' and unprecedented galaxy in the early Universe could 'help us understand how the cosmic story began', astronomers say. GS-NDG-9422 (9422) was found approximately one billion ...

In the vast expanse of the universe, the Milky Way Galaxy holds a special place in our hearts. It is our home, and after studying it for decades from our cosmic residence nestled within one of its ...

Head-scratching observations of distant galaxies are challenging cosmologists’ dominant ideas about the universe, potentially leading to the implication that the strange substance called dark matter ...

For decades, astronomers have treated dark matter as the invisible scaffolding of the cosmos, a mysterious substance that outweighs normal matter and shapes galaxies. A new wave of research is now ...

After combing through NASA's James Webb Space Telescope's archive of sweeping extragalactic cosmic fields, a small team of astronomers at the University of Missouri says they have identified a sample ...
