Galaxie zakončují aktivní fázi svého života v okamžiku, kdy se v nich přestanou tvořit nové hvězdy. Až dosud se ale astronomům nedařilo spolehlivě zdokumentovat tento proces ve vzdáleném vesmíru. S použitím radioteleskopu ALMA, jehož evropským partnerem je ESO, vědci objevili galaxii, která přišla téměř o polovinu plynu potřebného pro formování dalších hvězd. Proces navíc probíhá překvapivou rychlostí – galaxie ztrácí každý rok plyn ekvivalentní hmotě 10 000 Sluncí. Členové výzkumného týmu se domnívají, že tento mimořádný jev nastartovala kolize s jinou galaxií, což by mohlo astronomy přimět k revizi modelů, kterými v současnosti popisují, jak galaxie přicházejí o schopnost vytvářet hvězdy.
