"This object is close to the distance limit expected for a galaxy cluster," said Stefano Andreon of the National Institute for Astrophysics in Milan. "We don't think gravity can work fast enough to make galaxy clusters much earlier."Source: TG Daily

The Chandra data were the final - but crucial - piece of evidence as they showed that JKCS041 was, indeed, a genuine galaxy cluster.
