Record-breaking Galaxy Cluster Discovered
COSMOS data across many different wavelengths, including X-ray, infrared and radio, has been used to set the record for the most distant galaxy cluster ever discovered. We may be seeing the cluster, named CL J1001+0220, just after it's formation and while it is in the process of a big 'baby-boom' of star formation. Read the full press release here. The paper was published in the Astrophysical Journal on August 30th and can be found here.
