For the first time, astronomers experienced a very distant one galaxy to die in a possible big breakout according to CNN.
Known as ID2299, the galaxy’s extinction was most likely caused by a collision with another galaxy that eventually merged into ID2299, the study reported.
The strong evidence that a collision could have resulted in a loss of gas is a tidal tail, which is a long stream of gas and stars that extends into space after two galaxies collide, said CNN citing the study.
The researchers observed how the galaxy emits almost half the gas used to form stars and loses about 10,000 suns of gas each year, meaning it runs out of fuel to form new stars by adding 46% of all cold gas the galaxy will be removed so far.
The study, led by Annagrazia Puglisi, lead researcher and postdoctoral fellow at Durham University in the UK and the Saclay Nuclear Research Center in France, was published in the journal on Monday Natural astronomy.

Astronomers captured this rare observation using the Atacama Large Millimeter / Submillimeter Array of telescopes in Chile.
According to the study, it took light from this galaxy about nine billion years to reach Earth. Since the universe is 14 billion years old, astronomers observe what it looked like when it was only 4.5 billion years old.
