For the first time ever, astronomers have seen a very far distance The galaxy He began to die in a potentially large breakthrough, According to CNN.

Galaxies die when the stars in which they live stop forming.

The study, known as ID2299, stated that the galaxy’s extinction was most likely caused by a collision with another galaxy, which eventually merged to create ID2299.

CNN, citing the study, said that the definitive evidence that the collision may have led to the loss of gas is the tail tide, a long stream of gas and stars extending into space after two galaxies collide together.

The researchers note that the galaxy ejects nearly half of the gas it uses to form stars, and loses the equivalent of 10,000 suns of gas each year, which means that it runs out of fuel to form new stars by removing 46% of the galaxy’s total cold gas. so far.

It has now lost nearly half of that gas, and is because it is still being produced stars At a rate hundreds of times faster than our trail, ID2299 will likely take a few tens of millions of years to die.

The study, led by Anagracia Puglisi, a lead researcher and postdoctoral researcher from the University of Durham in the United Kingdom and the Saclay Center for Nuclear Research in France, was published in the journal Monday. Natural Astronomy.

„This is the first time that we have observed a massive typical star-forming galaxy in the distant universe, on the verge of death due to a massive cold gas emission,“ Boglesy said in a statement, according to CNN. “Mergers can result from expulsions and that winds and tidal tails can appear very similar,” said Emmanuel Daddy, co-author of the study and astronomer at Saclay. “This may lead us to review our understanding of how galaxies die.”

Astronomers captured this rare observation using the Atacama’s large millimeter / sub-millimeter array of telescopes in Chile.

According to the study, it took light from this galaxy about nine billion years to reach Earth, meaning that since the universe is 14 billion years old, astronomers are observing how it appeared when it was only 4.5 billion years old.
