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...

Hubble Captures Gas Escaping Sideways Spiral Galaxy NGC 4388 in Virgo Cluster
Hubble has captured a glowing plume of gas escaping the spiral galaxy NGC 4388 in the Virgo cluster. Moving through hot intracluster gas, the galaxy sheds material, partially energised by its central black hole. Multi-wavelength observations reveal the impact of both environmental forces and central activity on galaxy evolution.

NASA Uses 'X-arithmetic' to Show How Black Holes Shape Galaxy Clusters
NASA's Chandra telescope has used a novel "X-arithmetic" technique to analyse X-ray data from galaxy clusters, showing how supermassive black holes influence hot gas structures and offering new insights into cosmic evolution.

Chandra’s New X-Ray Mapping Exposes the Invisible Engines Powering Galaxy Clusters
NASA’s Chandra X-ray Observatory has released stunning colour-coded galaxy cluster images that reveal shock waves, cooling gas, and cavities carved by supermassive black holes. By separating X-ray light into different energy bands, astronomers can now visualise hidden cosmic processes that shape the universe’s largest structures and control how...

James Webb Telescope May Have Spotted First Generation of Stars in the Universe
Astronomers using JWST may have discovered Population III stars in cluster LAP1-B, offering new insights into early galaxy formation and the universe’s first luminous objects. JWST observations suggest Population III stars may have formed 13 billion years ago, helping trace early galaxies. These stars might be building blocks for larger galaxies ...

Ursa Major III May Be a Star Cluster, Not a Dark-Matter Dwarf Galaxy
Astronomers have long thought Ursa Major III, also called UNIONS 1, was a dark-matter-packed dwarf galaxy. But new simulations suggest it may instead be a compact star cluster bound by black holes and neutron stars. Located 30,000 light-years away, Ursa Major III contains just ~60 visible stars yet shows puzzlingly high stellar velocities. The new ...

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,...
