New findings explain the Phoenix cluster's mysterious starburst. Data confirm the cluster is actively cooling and able to generate a huge amount of stellar fuel on its own.
Recently discovered Phoenix galaxy cluster is the most massive and luminous celestial body ever observed, but just how big is it?
Writing in the journal Nature this week, astronomers say they've found a massive galaxy cluster that's pumping out stars at a record pace. Astronomer Michael McDonald describes the finding, and ...
Indeed, the Phoenix cluster is the most X-ray luminous galaxy cluster found yet, about 35 percent brighter than the previous record holder.
Like its mythological namesake, the Phoenix Cluster burns with blisteringly hot gas, which cools to birth stars. The James Webb Space Telescope has now learned how this galaxy cluster does it.
Astronomers have found an extraordinary galaxy cluster, one of the largest objects in the universe, that is breaking several important cosmic records. Observations of the Phoenix cluster with NASA ...

The Phoenix cluster was first spotted in 2010 by astronomers using the South Pole Telescope in Antarctica. The cluster comprises about 1,000 galaxies and lies in the constellation Phoenix, after ...
For the Phoenix cluster's central galaxy, which should be well past the stage of extreme cooling, the presence of ultracold gas presented a puzzle.
