Astronomers Find ‘Impossible’ Galaxy ACDG-2 With Virtually No Stars and a Massive Dark Matter Core
Astronomers have identified CDG-2, a faint galaxy in the Perseus cluster that appears to be composed almost entirely of dark matter. Located 300 million light-years from Earth, it was discovered by tracking globular star clusters using data from Hubble, Euclid, and Subaru telescopes. Scientists estimate that about 99% of its total mass is dark matt...

NASA Finds Most Distant Calm Galaxy Cluster Ever Seen in Early Universe
Astronomers using NASA’s Chandra X-ray Observatory have discovered SPT-CL J2215-3537, a massive galaxy cluster located 8.4 billion light-years away. Nicknamed the “Champagne Supernova” cluster, it is the most distant relaxed cluster ever observed, showing no signs of recent collisions. Its calm structure and active star formation challenge ex...

NASA’s Chandra Spots Champagne Cluster Formed by a Massive Galaxy Collision
Discovered on New Year’s Eve 2020, the Champagne Cluster is a striking pair of colliding galaxy clusters revealed through combined X-ray and optical observations. NASA’s Chandra X-ray Observatory shows superheated gas stretched and distorted, exposing a massive cosmic collision hidden from visible light alone. Studied by UC Davis astronomers, t...

Earendel: JWST Suggests the Most Distant Star May Be a Star Cluster
Earendel, the farthest object ever seen, was first thought to be a single massive star from the early universe. New findings from JWST suggest it may instead be a star cluster, with many stars grouped together. Scientists used gravitational lensing to spot Earendel, which made its light appear thousands of times brighter.

Hubble Unveils Dark Matter Web in Stunning Abell 209 Galaxy Cluster Image
NASA/ESA’s Hubble Space Telescope has released a stunning new image of Abell 209, a massive galaxy cluster 2.8 billion light-years away in Cetus. The golden cluster houses over 100 galaxies, but beneath them lies an invisible web of hot gas and dark matter. Using gravitational lensing, Hubble reveals curved arcs of light from background galaxies,...

NASA’s Hubble and Webb Discover Bursting Star Formation in Small Magellanic Cloud
NASA’s Hubble and Webb telescopes have captured spectacular images of NGC 460 and NGC 456, two star clusters in the Small Magellanic Cloud. These young, open clusters are filled with massive, hot stars that trigger new star formation by carving nebulae. The findings provide insights into early universe conditions and interstellar medium behaviour...

Most Distant Mini-Halo Discovered in Galaxy Cluster 10 Billion Light-Years Away
Astronomers have uncovered the most distant mini-halo ever detected, located around the galaxy cluster SpARCS1049, a staggering 10 billion light-years from Earth. Using the LOFAR radio telescope network, which spans eight European countries, researchers detected a faint, diffuse glow—evidence of a giant cloud of high-energy particles and magnetic...

Two Galaxy Clusters That Collided Previously Are All Set To Smash Again
Despite their enormous distance, the galaxy clusters are gravitationally bound and slowly turning back for another high-speed impact.

New Study Finds Hercules-Corona Borealis Great Wall Bigger and Nearer Than Thought
GRBs uncover a more massive and closer Hercules–Corona Borealis Great Wall, reshaping cosmic scale theories.Astronomers have found that the Hercules–Corona Borealis Great Wall—the largest known structure in the universe—is even larger and closer than previously thought. Spanning 10 billion light-years, this immense cluster of galaxies was t...

James Webb Space Telescope Reveals a Stunning Einstein Ring in Hydrus
A striking new image from the James Webb Space Telescope reveals an Einstein ring in the Hydrus constellation. The phenomenon occurs when a massive foreground galaxy bends light from a hidden background galaxy, forming a near-perfect ring. This effect, predicted by Einstein’s theory of general relativity, helps astronomers study galaxies from the...
