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. The core of a massive ...

Astronomers have confirmed the first example of a supermassive black hole unable to prevent copious numbers of stars forming in the core of galaxy cluster where it resides. This result provides new ...

For the first time, astronomers have spotted active bursts of stars forming in a galaxy at the center of a dense cluster. In galaxy clusters, supermassive black holes in the central galaxies typically ...

The faraway Phoenix galaxy cluster may be the biggest and brightest such structure ever discovered, and it's forming stars at an unprecedented rate, scientists announced today (Aug. 15). Here's a ...

The core of a massive cluster of galaxies appears to be pumping out far more stars than it should. Now researchers at MIT and elsewhere have discovered a key ingredient within the cluster that ...

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 ...
