Scientists analyse brightest gamma ray burst ever detected

But where is the supernova??

XMM-Newton images recorded 20 dust rings, 19 of which are shown here in arbitrary colours. The image merges observations made two and five days after GRB 221009A erupted. Dark stripes indicate gaps between the detectors. GRB221009A is only the seventh gamma-ray burst to display X-ray rings, and it triples the number previously seen around one.
