Ophiuchus Supercluster explosion
According to NASA and others, the Ophiuchus Supercluster explosion was the biggest explosion seen in the observable universe since the MS 0735+74 explosion.
This extremely powerful eruption occurred in the Ophiuchus Supercluster, which is located about 390 million light-years from Earth. A paper describing these results appeared online on 27 February 2020 in The Astrophysical Journal, and a preprint is available on arXiv. This explosion was caused by a supermassive black hole spraying out jets of extremely active particles.. Its total huge energy is estimated to 5 X 1061 erg, or 5 X 1054 J.
Furthermore, the cavity produced by the outburst is so big that would be possible to put 15 galaxies of Milky Way's dimensions in a row.
The authors of this paper are Simona Giancintucci, Maxim Markevitch, Melanie Johnston-Hollitt, Daniel Wik, Qian Wang, and Tracy Clarke. The 2016 paper by Norbert Werner et al. was published in the Monthly Notices of the Royal Astronomical Society.
This observation is a result of collaboration among various space-based and Earth-based observatories including the Hubble Space Telescope, the Chandra X-ray Observatory, ESA’s XMM Newton X-ray space observatory and radio data from the Murchison Widefield Array in Australia and the Giant Metrewave Radio Telescope in India.
