The galaxy glows brightly when it produces 4,500 times more stars than the Milky Way

Galaxy SPT0346-52, located 12.7 billion light-years from Earth, produces new stars each year with a total volume of 4,500 times the Milky Way.

Astronomers discovered the galaxy named SPT0346-52 , located 12.7 billion light-years from Earth, producing stars with a total mass of 4,500 times the Sun each year, Futurity on 12/12 reported.

By using ground and space telescopes, they recorded ultra-bright infrared rays emitted from the galaxy but they did not come from a black hole.

"We determined that this galaxy does not have a black hole. Its bright light comes from newly formed stars," said Jingzhe Ma, a graduate student at the University of Florida, USA, who is in charge of research and giving. know.

SPT0346-52 is one of Jingzhe Ma The total volume of stars that it produces each year is 4,500 times the mass of the Sun. Meanwhile, the Milky Way every year only forms the number of new stars with the total mass equal to the Sun.

"Astronomers call the galaxy with many stars formed in it as " starburst "galaxies , but that term is not enough to describe SPT0346-52, so we call it galaxy. "super exploding star" , astronomical professor Anthony Gonzalez, co-author of the study, explained.

The rapid star formation rate means that a large source of cold gas in the galaxy is being transformed into stars with unusually high efficiency. Scientists hope that by studying many galaxies like SPT0346-52, they can better understand the formation and development of large galaxies as well as the super black hole in its center.

"Astronomers have known for many decades that black holes and new stars develop simultaneously in the host galaxy. However, SPT0346-52 is very special because we have observed many newly formed stars. but there is no sign of a growing black hole, so we want to study this galaxy in detail to understand the origin of new star formation and its effect on the development of black holes.
