The Milky Way galaxy has a graveyard of dead stars that stretches three times the height of the galaxy, according to new research.
Astronomers found the ancient stellar remnants when they mapped this"galactic underworld" for the first time.
People are also reading… Modern neutron stars and black holes formed in the Milky Way are easier to spot because they stay within our galaxy and conform to its shape. But the ancient stars that existed in the young, evolving Milky Way galaxy were like stellar ghosts when the researchers tried to find them.
"One of the problems for finding these ancient objects is that, until now, we had no idea where to look," said study coauthor Peter Tuthill, professor at the School of Physics and director of the Sydney Institute for Astronomy at The University of Sydney in Australia, in a statement. "Supernova explosions are asymmetric, and the remnants are ejected at high speed — up to millions of kilometers per hour — and, even worse, this happens in an unknown and random direction for every object," said lead study author David Sweeney, a doctoral student at the Sydney Institute for Astronomy of The University of Sydney, in a statement.
The new map includes where the stars were born within the Milky Way, where they exploded and their eventual resting places. "It was a bit of a shock," said study coauthor Dr. Sanjib Sharma, a research fellow at The University of Sydney, in a statement."I work every day with images of the visible galaxy we know today, and I expected that the galactic underworld would be subtly different, but similar in broad strokes. I was not expecting such a radical change in form."
