Superblast from the past

Post by brian livesey »

Astrophysicists have detected a cosmic explosion five times bigger than any previous detections. Melanie Johnston-Hollit, co-author of the report on the blast in "The Astrophysics Journal", said to the media: "It would be like setting off 20 billion billion tonnes of TNT explosions every thousandth of a second for 240 million years." :shock:
The black hole event occurred 390 million light years away in the Ophiuchus galaxy cluster. Researchers in the US and Europe used X-ray telescopes to map the region affected by the event. The explosion created a "cavity" in the galaxy cluster that was initially thought to be too big to have been caused by a black hole event.
