VIVA – Simply, the Milky Way looks like stars scattered in the vast sky. However, the Milky Way is a galaxy around which there is a solar system. Recently, scientist says that the Milky Way is a giant graveyard. This Milky Way is a place where stars are born, burn, and die.
Massive stars in the Milky Way that died billions of years ago became supernovae and turned into two types of objects. With the outer layer exploding, the remaining core enters the afterlife as a very compact neutron star or collapses in on itself and forms a black hole.
What remains of these ancient stars is known to scientists as the galaxy's underworld, where its secrets are buried in darkness until now.
After nearly turning back time to see how and when these early stars were born, lived, and died, researchers have finally created the first digital map of the galactic underworld.

Researchers can do this by analyzing observations of dead stars scattered across galaxies such as neutron stars and black hole and figuring out when they were born and how they evolved.
Researchers also found a grave that is three times the current height of the Milky Way, as quoted from the Space website, Wednesday, October 12, 2022.
The newborn Milky Way, where these early stars lived, looked very different from the galaxy we see today. Even his spiral arms weren't fully extended yet.
This grave map was created by astronomer David Sweeney and his colleagues at the University of Sydney. The new map reveals not only where the bones of this old star could be hidden, but also about a third of the remains lying around it have been or are currently there.
