Ancient Cluster Still Producing Stars

Texas A&M Professor Kim-Vy Tran and her colleagues have discovered that the extremely distant star cluster CLG J02182-05102 produces at least hundred of new stars annually--maybe thousands.

Casey Papovich discovered the cluster in May. At that time he was quoted as saying, "We are seeing something already aged and red like a younger version of the Coma Cluster from a distant, bygone era." Galaxy clusters are the largest gravitationally-bound objects in the Universe.

A quite bizarre aspect of this discovery is that the star births are happening at a higher rate in the center than at the edges of the cluster. That's the opposite of what we observe in the local section of the Universe.

MIPS is a far-infrared photometer--an imaging camera, but for wavelengths of 24, 70 and 160 microns. MIPS can also perform simple spectroscopy.

Well, to no surprise it made Berman's list of strangest objects. The list is quite fun to peruse, and this anomalous shouldn't-be-so-developed thing is right at home.
