Why it's so special: Galaxy clusters act as a magnifying lens, shining light on the faintest and most distant objects — a phenomenon known as gravitational lensing. On the rarest of occasions, galaxy ...

A new study reports the first direct observation of merging star clusters in the nuclear region of dwarf galaxies. This detection confirms the feasibility of this formation route for nuclei in dwarf ...

“The Euclid data clearly confirm the presence of the extremely faint, diffuse light of CDG-2, revealing the galaxy behind the ...

The James Webb Space Telescope (JWST) has provided groundbreaking insights into the Bullet Cluster, a cosmic collision zone located 3.8 billion light-years from Earth. The JWST’s enhanced imaging ...

A massive, spacetime-warping cluster of galaxies is the setting of today’s NASA/ESA Hubble Space Telescope image. The galaxy cluster in question is Abell 209, located 2.8 billion light-years away in ...

Abell 370, a galaxy cluster located nearly 4 billion light-years away from Earth features several arcs of light, including the "Dragon Arc" (lower left of center). These arcs are caused by ...

Celebrate the New Year with the “Champagne Cluster,” a galaxy cluster seen in this new image from NASA’s Chandra X-ray Observatory and optical telescopes. Astronomers discovered this galaxy cluster ...

A stronomers report the discovery of a truly incredible object. They are calling it Candidate Dark Galaxy-2 (CDG-2), a somewhat humdrum name for something truly incredible, a galaxy made almost ...

Astronomers working with NASA’s James Webb Space Telescope have produced the sharpest wide-area map of dark matter ever assembled, more than doubling the resolution of previous efforts built on Hubble ...

New findings explain the Phoenix cluster's mysterious starburst. Data confirm the cluster is actively cooling and able to generate a huge amount of stellar fuel on its own. The core of a massive ...
