A galaxy cluster once thought to be “dead” is unexpectedly forming stars at an astonishing rate, challenging established ...

JWST’s observations confirm missing cooling gas in the Phoenix Cluster, explaining its rapid star formation rate.

Like its mythological namesake, the Phoenix Cluster burns with blisteringly hot gas, which cools to birth stars. The James ...

The Phoenix Cluster's central galaxy is about 5.8 billion light-years away and should be mostly done with star formation. Many galaxy clusters have a region of hot gas in the intracluster medium (ICM) ...

The core of a massive cluster of galaxies appears to be pumping out far more stars than it should. Now researchers at MIT and ...

Researchers use the James Webb Space Telescope to unravel the mystery of rapid star formation in the Phoenix galaxy cluster, ...

Researchers using NASA’s James Webb Space Telescope have finally solved the mystery of how a massive galaxy cluster is ...

NASA's James Webb Space Telescope (JWST) has recently made observations about galaxy clusters that will help shape our ...

New Webb Telescope data uncovers missing gas that enables star formation in the Phoenix cluster, solving a cosmic puzzle.

The core of the Phoenix cluster is shown across the whole electromagnetic spectrum. The bright purples represent X-rays produced by the hot gas, and the dashed purple outlines show regions where this ...

Most massive galaxies have black holes at their cores that emit energetic particles, heating the galaxy’s gas and dust.
