The Milky Way Galaxy that houses Earth is just over 13 billion years old. Still, in its youth, the galaxy has several billion years more to go. However, not all galaxies are that lucky. Astronomers have now discovered a dying galaxy as it loses its ability to form new stars.
The merging galaxy formed 4.5 billion years ago is dubbed ID2299 and is ejecting gases equivalent to 10,000 Suns-worth of gas a year, rapidly losing its fuel core.
The research published in Nature Astronomy titled “A titanic interstellar medium ejection from a massive starburst galaxy" suggests that the event was triggered by a galactic collision between two galaxies nine billion years into the past.
