Scientists Discover Rare, Nearly Invisible Galaxy Dominated By Dark Matter
According to researchers, approximately 99 percent of this galaxy's total mass is dark matter.

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 Capture First Detailed View of Hot Gas Swirling Around Black Holes
Japan’s XRISM X-ray observatory has delivered the first detailed maps of hot gas swirling around supermassive black holes in the Virgo and Perseus galaxy clusters. The data reveal intense turbulence, like cosmic storms driven by black hole jets. This churning heats the gas, stopping it from cooling and collapsing into new stars, explaining why cl...

NASA's New High-Resolution Map Shows Dark Matter In "Stunning Detail"
The map provides insights into the universe's evolution, tracing dark matter's influence back to when galaxies were forming most actively.

James Webb Helps Astronomers Chart the Universe’s Hidden Dark Matter
Astronomers have created the sharpest map yet of dark matter using deep observations from NASA’s James Webb Space Telescope. By analysing the gravitational distortion of hundreds of thousands of distant galaxies, the team traced invisible dark matter across a large region of the sky. The results confirm that dark matter forms the scaffolding arou...

Astronomers Discover Shockingly Hot Young Galaxy Cluster That Defies Theory
Astronomers have identified an exceptionally hot galaxy cluster forming just 1.4 billion years after the Big Bang. Observations reveal gas temperatures far exceeding theoretical limits, suggesting an unexpectedly violent early formation. The discovery challenges standard models of galaxy cluster evolution and points to intense activity from starbur...

Hubble Data Reveals Previously Invisible ‘Gas Spur’ Spilling From Galaxy NGC 4388’s Core
The elliptical galaxy NGC 4388, situated in the Virgo Cluster approximately 60 million light-years from Earth, features an intriguing long tail of glowing gas, as shown in a recent image uploaded to the Hubble site in late 2025. This galaxy, viewed edge-on from Earth’s perspective, displays a bright spur of ionized gas spilling out from its core....

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...
