Look at the rare disastrous fusion of galaxies taken by the Spitzer telescope.

Using a telescope, scientists from the GOALS project, who are searching for galaxy mergers, photographed

object VV 340.In it, several galaxies of approximately the same size collide with each other - the actual collision has not yet occurred, but the objects are already strongly influencing each other with gravity.

Scientists suggest that the center mergedgalaxies appear supermassive black holes - they become the cause of the cessation of star formation. The black hole tightens all surrounding matter, including the cosmic zag and dust. As a result, the galaxy is slowly dying.

Previously, scientists from the LOFAR radio interferometer team announced the discovery of several thousand new galaxies, the existence of which astronomers did not previously know.
