Scientists discovered a vast “galactic underground” that is filled with the remains of ex-suns, black holes, and neutron stars.
The galactic graveyard measures three times the height of our Milky Way and many of its remnants are three times larger than our sun. These findings were published in Monthly Notices of the Royal Astronomical Society.
David Sweeney was the study’s principal author. He is a Ph.D. student at the Sydney Institute for Astronomy.
Sweeney stated that these compact remnants of dead star stars have a fundamentally different structure and distribution than the visible galaxy. The ‘height” of the galactic subworld is three times greater than the Milky Way. Amazingly, 30% of the objects have been completely ejected out of the galaxy.
Sweeney and his university team were able to create maps that indicated where the neutron stars and black holes are located in the galactic graveyard. These models show how the stars died and were born.
Researchers noted that older black holes and fallen suns are more difficult to find than younger ones.
Peter Tuthill, an Astronomy Professor at the Sydney Institute for Astronomy worked with Sweeney. He noted that finding the stars was like searching for the mythical elephant’s graveyard.
He stated in a press release that “the bones of these rare massive star stars had to have been out there, but it seemed like they shrouded themselves in mystery.” “The galaxy’s oldest neutron stars were formed when it was younger. They were shaped differently and then went through complex changes that spanned billions of years. It was a difficult task to model all this and find them.
Scientists estimate that billions upon billions of stars similar to the ones found in the Galaxy’s beginning were formed, but that the recently discovered carcasses were probably ejected from the galaxy by a Supernova.
