Extreme Galaxy Cluster Birthing Stars at Excessive Rate

by Adam Mann
The newly discovered Phoenix cluster may be one of the most extreme objects ever observed, being among the most massive, luminous, and productive clusters in the universe.

    With its black hole not producing powerful enough jets, the center of the Phoenix Cluster is buzzing with stars that are forming about 20 times faster than in the Perseus cluster. This rate is the highest seen in the center of a galaxy cluster but not the highest seen anywhere in the Universe. However, the overall record-holding galaxies, located outside clusters, have rates only about twice as high. Optical/UV/X-ray composite image of the Phoenix cluster, with a pull-out of the central

    Phoenix Galaxy Cluster May Be Most Massive Ever (IMAGES)

    New galaxy discouvered! Wow! An extraordinary cluster of faraway galaxies is shattering or challenging a number of cosmic records, weighing in as potentially the most massive cluster known. The colossal galaxy cluster is also the brightest in X-ray light, and the galaxy at its heart apparently gives birth to more than 700 stars per year – hundreds of times as fast as our Milky Way forms stars, researchers say.

Central area of the Milky Way galaxy, released by astronomers at the European Southern Observatory's Paranal Observatory in Chile. The photo shows 84 million stars in an image measuring 108,500×81,500, which contains nearly 9 billion pixels, and is actually a composite of thousands of individual photographs shot with the observatory's VISTA survey telescope.
