Old, ultra-faint and metal-poor star cluster discovered

An international team of astronomers reports the discovery of a new star cluster (SC) as part of the DECam Local Volume Exploration (DELVE) survey. The newfound cluster, designated DELVE 6, is ultra-faint, metal-poor and is estimated to be about 9 billion years old. The finding was detailed in a paper published June 7 on the pre-print server arXiv.
