ID2299

ID2299 is a galaxy that is currently found to be dying out. In a first, Atacama Large Millimeter/submillimeter Array (ALMA) captured the galaxy ejecting nearly 50% of its star-forming gas. The speed of this ejection was estimated to be equivalent to 10,000 Sun-worth of gas a year. This galaxy is also rapidly forming stars, which will result in the remaining gas in ID2299 be consumed over tens of millions of years. This event has been triggered by a collision with another galaxy.
