ID2299

ID2299 is an elliptical galaxy 9 billion light-years away.^[1][2] It was found and detailed in January 2021, due to its phenomenon of catastrophic gas loss. This is due, unless the prolonged observations are inexplicably misleading or a poorly understood mechanism is at hand, to a catastrophic merger – prompting a secondary part of the galaxy that hosts rapid star formation. ID2299's high star formation rate is far outweighed by its ejection of gas. Its trailing tail has grown to approximately half of its size. ID2299 is extrapolated to lose so much more gas that it will only remain active – capable of new star formation – for a few more tens of millions of years.
