February 2020 Sci News reported on this galaxy XMM-2599 discovered about 12 billion light-years away.
Astronomers using the Multi-Object Spectrograph for Infrared Exploration (MOSFIRE) at the W. M. Keck Observatory have discovered an ultramassive galaxy 12 billion light-years away from Earth. The unusual galaxy, named XMM-2599, formed stars at a very high rate and then died; why it suddenly stopped forming stars is unclear.sci-news.com
As I have reported many times in the past, the big bang paradigm is a priori accepted as truth and whatever is discovered is fitted into that story-line. In this case it is another of those objects that is simply too big too early in the alleged history of the big bang universe.
“More remarkably, we show that XMM-2599 formed most of its stars in a huge frenzy when the Universe was less than one billion years old, and then became inactive by the time the Universe was only 1.8 billion years old.”
Dr. Forrest and colleagues used spectroscopic observations from the MOSFIRE instrument to make detailed measurements of XMM-2599 and precisely quantify its distance.
