Astronomers studying the Ophiuchus galaxy cluster, about 390 million
light-years away, have come to the realization that a cavity within
the cluster's plasma which had been detected previously with X-ray telescopes
betrays the radio fossil record of what they describe as the largest
known explosion in the Universe since the Big Bang.
The discovery was made using four telescopes; NASA’s Chandra X-ray
Observatory, ESA’s XMM-Newton, the Murchison Widefield Array (MWA) in
Western Australia and the Giant Metrewave Radio Telescope (GMRT) in India.

The finding has been reported in a paper entitled ‘‘Discovery of a giant
radio fossil in the Ophiuchus Galaxy Cluster’, published in The Astrophysical
Journal on February 28th, 2020.
