Constellation Palomer 5, tails on both sides. The center is 130 light-years wide and the tails are 11,000 light-years long on both sides.

This is the lifespan of the Palomer 5 star cluster, which swallows 124 black holes from the inside. Located 65,000 light-years from Earth, Palomer 5, discovered in 1950, is one of 150 Milky Way galaxies. These are areas where millions of stars have accumulated. Palomer 5 has a special feature: the “tails” in its center, from which the stars escape.
