"We know very well that black holes can be formed by the collapse of large stars, or as we have seen recently, the merger of two neutron stars," said Savvas Koushiappas, an associate professor of physics at Brown University and coauthor of the study with Avi Loeb from Harvard University. "But it's been hypothesized that there could be black holes that formed in the very early universe before stars existed at all. That's what we're addressing with this work."

A background object in images of the nearby Andromeda galaxy has revealed what could be the most tightly coupled pair of supermassive black holes ever seen. “We were looking for a special type of star in M31 and thought we had found one,” said Trevor Dorn-Wallenstein, a University of Washington doctoral student in astronomy and lead author on the paper describing this discovery. “We were surprised and excited to find something far stranger!”

“Despite all odds, we see the best evidence yet that low-mass stars are forming startlingly close to the supermassive black hole at the center of the Milky Way,” said Farhad Yusef-Zadeh, an astronomer at Northwestern University in Evanston, Illinois, and lead author on the paper. “This is a genuinely surprising result and one that demonstrates just how robust star formation can be, even in the most unlikely of places.”
