The most powerful explosion ever seen seems to come from a supermassive black hole devouring a colossal cloud of gas, blasting out enormous amounts of energy as it eats
In the distant universe, a supermassive black hole seems to be devouring an enormous cloud of gas, producing an
the likes of which we’ve never seen before. So far, it has released about 100 times the total energy the sun will release in its entire lifetime, and it hasn’t finished yet. This gigantic inferno, called AT20211wx, was first spotted in 2020 by the Zwicky Transient Facility in California.at the University of Southampton in the UK and his colleagues performed a series of follow-up observations with other observatories in the years since then. “We see various different large explosions and flashes in the universe, but nothing anywhere near what we see here,” Wiseman says.
The only cosmic objects brighter than AT20211wx are quasars, which are caused by a continuous flow of gas into a. This explosion, which brightened by a factor of more than 15 over the course of about four months and then began to steadily dim, is still ongoing. The observations seem to point to a supermassive black hole devouring a gargantuan cloud of gas, possibly 100 times larger than the solar system or even bigger.

Galactic Mistake? Astronomers May Have Solved the Mystery of the Runaway Supermassive Black HoleA study carried out by a team of researchers at the Instituto de Astrofísica de Canarias (IAC) has shown that an unusually thin structure of stars, recently discovered by the Hubble Space Telescope, could be a galaxy seen edge-on. This finding goes against the original interpretation in which a flee
