James Webb Telescope Finds Galaxies Nearly as Old as the Early Universe
NASA’s James Webb Space Telescope has revealed early galaxies that appear almost as old as the universe itself. By analyzing 31 galaxies at high redshift, researchers estimated stellar ages of around 600 million years—close to the universe’s age at that epoch. One galaxy may even seem older than the universe, posing a potential challenge to t...

AI Identifies More Than 1,300 Unusual Objects in Hubble Space Telescope Images
Artificial intelligence has combed through decades of Hubble Space Telescope data, revealing hundreds of unusual celestial objects that astronomers had missed. ESA’s AnomalyMatch neural network scanned around 100 million image cutouts in just days, flagging more than 1,300 anomalies. Among them are colliding galaxies, rare gravitational lenses, a...

JWST Uncovers the Origins of the Universe’s First Supermassive Black Holes
James Webb Space Telescope observations reveal that the earliest supermassive black holes formed from massive gas clouds collapsing directly into heavy seeds. This process bypassed normal star formation, allowing black holes to reach millions of solar masses within just 200–500 million years after the Big Bang, solving a long-standing cosmic myst...

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...

NASA’s Chandra Observatory Reveals 22 Years of Cosmic X-Ray Recordings
NASA’s Chandra X-ray Observatory has released an expanded source catalogue spanning 22 years of observations, covering around 400,000 cosmic X-ray sources. The dataset captures high-energy events across the universe, from black holes to stellar remnants, and can be combined with Hubble and James Webb data. Scientists say it offers an unprecedente...

NASA’s JWST Uncovers a ‘Feeding Frenzy’ That Births Supermassive Black Holes
Astronomers may have solved how supermassive black holes formed so soon after the Big Bang. New simulations show that gas-rich, turbulent early galaxies allowed brief super-Eddington feeding bursts, enabling ordinary stellar-mass black holes to grow rapidly into the giants seen by JWST.

NASA's James Webb Space Telescope Might Have Spotted Hidden Supermassive Black Holes
Mysterious “little red dots” spotted by the James Webb Space Telescope may not be tiny galaxies after all. A new study suggests they are supermassive black holes wrapped in dense gas and dust, perfectly disguised in the early universe and shining intensely in infrared light.
