First ever map of Milky Way’s galactic graveyard revealed

The Milky Way is a gargantuan graveyard. Stars are born, burn out and die, but they don’t just vanish — and the galaxy is haunted by their corpses.

Massive stars in the Milky Way that died billions of years ago went supernova and morphed into two types of objects. With their outer layers blasted away by the force of the explosion, the cores that were left either entered the afterlife as extremely compact neutron stars or collapsed in on themselves and formed black holes. What remains of these ancient stars is known by scientists as the “galactic underworld” that has kept most of its secrets buried in the dark until now.
