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...

Astronomers Find ‘Dark Object’ 11 Billion Light-Years Away Through Gravity
Astronomers have observed a completely dark mysterious object, which is approximately a million times more massive than the mass of the Sun. It is found about 11 billion light-years distant and was identified in 2025 through its gravitational impact on the light of a background galaxy. This renders it the farthest object ever to have been observed ...

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...

Neutrino Detectors May Unlock the Search for Light Dark Matter, Physicists Say
Physicists now believe that massive neutrino detectors—built to observe rare solar and cosmic particles—could also detect extremely light dark matter that traditional experiments miss. By monitoring subtle annual variations in their background signals, observatories like JUNO and Borexino may open a new frontier in uncovering the universe’s m...

Scientists Finds Galaxies Rotating Together Inside Massive Dark Matter Thread
The filament is a part of the vast cosmic web composed primarily of dark matter and interspersed with lighter layers of normal matter.

Dark Matter May Have Been Seen for the First Time in NASA Gamma-Ray Data
A new analysis of NASA’s Fermi telescope data reveals a faint gamma-ray halo around the Milky Way’s core, matching predictions for annihilating dark-matter particles. Researchers say no known astrophysical source fits the signal, raising the possibility of the first direct evidence of dark matter. Experts, however, stress caution and call for v...

Astronomers Spot Mysterious Dark Object In Distant Universe, It's A Million Times Larger Than The Sun
A mysterious object with a mass equivalent to 1 million suns has been detected in space, but its nature remains unknown.

New Inelastic Dark Matter Model Could Bypass Current Limits of Particle Detection
A new study from Brazil proposes an inelastic dark matter model using a massive vector mediator, potentially explaining the correct abundance of dark matter while evading existing detection limits. This fresh approach could revive interest in previously ruled-out models and offers experimental pathways to test these elusive particles through the in...

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,...
