This galaxy makes you want to see the fjords
Astronomers consider galaxies to be alive or dead, depending on whether a certain group is still producing new stars or not. Star groups in which star formation has slowed considerably but has not yet been stopped are classified as deleting galaxies . These objects are not as bright as active galaxies, but not as dark as dead families of stars. This classification helps astrophysicists study galaxies across the cosmos.
"This result is consistent with the fact that these dying giant systems when they were alive and forming stars may not have been as extreme compared to the average population of galaxies," explains  Francesco Valentino, assistant professor at the Cosmic Dawn Center at the Niels-Bohr Institute.
Our own Milky Way is still very much alive, because stars are born everywhere in our galaxy. However, not far from us is M87, a dead galaxy that is home to a monster black hole that was recently photographed by researchers using a global network of radio telescopes. The existence of this huge supermassive black hole – much larger than that in the middle of the Milky Way (19459007) (19459008) – could have played a significant role in the downfall of the galaxy, the researchers said.
