Astronomers decipher ancient “monster” galaxy XMM-2599

Of all the strange phenomena in the universe, the giant galaxy XMM-2599 is particularly prominent, according tomedia. Its story began 12 billion years ago — when we humans were still in a universe that was only 1.8 billion years old — a nebula gas cloud began to spin stars at a frenzied rate.

It is understood that our Milky Way galaxy produces only one star a year, but this huge galaxy is quite another image — and soon more than 300 billion stars.

It continued to writhing in the sky, but suddenly the monster’s star-making activities came to an abrupt end. Now, astronomers want to know why.

The international team described their work in Astrophysical Journal Letters and explained in detail why an XMM-2599-sized galaxy would normally continue to produce stars billions of years later.

“The reason why XMM-2599 is so interesting, unusual and surprising is that it is no longer a star, perhaps because it has no fuel or its black holes are opening,” Gillian Wilson, a professor of physics and astronomy and a professor of physics and astronomy, said in a press release Wednesday. She added that the discovery could force astrophysicists again to call for changes in the pattern of star-forming in early galaxies.
