wandflower are considered dead once they barricade making new stars . These dead galaxies have incline out of natural gas to make new stars . Without this , they will slowly grow ruby as brilliant blue stars go supernova , leaving behind the smaller , dimmer stars . This will happen to all galaxies but uranologist had never clearly see the beginning of this process of a beetleweed about to go in the very early in the universe , until now . This is a of the essence window into galaxy evolution .
In a new paper published inNature Astronomy , an external team of researchers introduces us to galaxy ID2299 . This celestial object is form whizz 550 clip faster than the Milky Way , which is known as a starburst Galax urceolata . But this galaxy is also fall behind gas in an unprecedented way . Every yr , it throws the equivalent of 10,000 Suns into intergalactic space , eject as " tidal can " .
That loss is removing 46 percent of all the cold gas from this Galax urceolata . Between this and the intense star - shaping , the galax will black market out of throttle in just a few 10 of million of years . This fact is even more dramatic consider that the galaxy is hold out through this event just 4.5 billion years after the Big Bang . That ’s just after cosmic in high spirits noon , when galaxies were produce stars at incredible rates .
" This is the first time we have observed a distinctive massive champion - form galaxy in the aloof Universe about to ' die ' because of a massive cold natural gas ejection , " said lead source Dr Annagrazia Puglisi , from Durham University in the UK and the Saclay Nuclear Research Centre ( CEA - Saclay ) in France , in astatement .
The squad believe that the cause for this spectacular issue is a hit with another galaxy . Galaxy merger often deliver anew lease of living to galax , add new gas and the conditions for intense genius - formation . This discovery suggests that they could also be fatal as the complex gravitational dance remove natural gas from the final galaxy .
" Our field of study suggests that gun riddance can be produced by mergers and that wind instrument and tidal arse can appear very like , " carbon monoxide gas - generator Emanuele Daddi of CEA - Saclay . " This might lead us to revise our understanding of how galaxies ' pop off ' . "
These groundbreaking observations were carried out using the Atacama Large Millimeter / submillimeter Array ( ALMA ) , currently the turgid radio telescope in the world , but more observations are involve . The squad hop to use ALMA once again to analyse this galaxy and its gasolene tail in more detail . They also hope to observe ID2299 in seeable light with next - coevals instruments such as the Extremely Large Telescope , which is look to come online in 2025 .
