Big Bang (cont.)

 

Astronomers are watching the biggest explosion in the Universe. And it just keeps exploding.

The Biggest Explosion in the Cosmos Just Keeps Going

"Now an international group of astronomers reports that it is observing one of the most violent and energetic acts of cosmic cannibalism ever witnessed, perhaps the biggest explosion seen yet in the history of the universe. Eight billion light-years from Earth, in the darkness beyond the constellation Vulpecula, a black hole perhaps a billion times as massive as the sun seems to be gorging on a humongous cloud of gas. A study of the phenomenon appeared Friday in Monthly Notices of the Royal Astronomical Society.

The study began on April 13, 2021, when the Zwicky Transient Facility, a small telescope that was busy looking for exploding stars, or supernovas, spotted a bright flash that did not fit expectations. Most supernovas fade after a few weeks; this one, known as AT2021lwx, kept going — and has continued to explode for three years now."

So, we'll just have to go take a closer look.

Or maybe not.
