Astronomers while exploring the enormity of the Milky Way have for the first time made a map of the graveyard in the galaxy, consisting of ancient dead stars. This basically consists of a large number of suns that have eventually run out of fuel and are now vanishing into black holes. The map is very different from the Milky Way with characteristic spiral arms and is much more puffed up because of kinetic energy. The so-called graveyard contains a third of the objects that have been flung out from the galaxy.
Astronomers from the Sydney Institute of Astronomy have recreated the full lifecycle of ancient dead stars and made the first detailed map showing where their corpses lie. This graveyard is three times larger in height than the Milky Way. Until now, researchers had no time where to look for these ancient carcasses because the oldest stars and black holes were created when the galaxy was formed and was very young and shaped very differently and then subjected to many changes. These neutron stars and black holes are formed when huge stars, eight times larger than the sun, exhaust their fuel and collapse.
Astronomers did not recognise these dead stars until now because since the galaxy was young these dead carcasses were flung out into interstellar space by the supernova that created them and hence slipped out of sight and knowledge. Astronomers said that the most exciting things about this galactic underworld are yet to come and now that they know where to look, suitable technologies are being invented for better research.
