摘要
One would expect a galaxy cluster to be a cluster of galaxies. Now a strange object has been discovered whose X-ray emission betrays it as a massive cluster, but which only contains one obvious galaxy at optical wavelengths. Odder still, this dark cluster is rich in heavy elements, presumably produced by stars - but what stars?
