Andromeda Galaxy’s first spinning neutron star found

Decades of searching in the Andromeda Galaxy has finally paid off, with the discovery of an elusive breed of stellar corpse — a neutron star, by ESA’s XMM-Newton space telescope. Neutron stars are the small and extraordinarily dense remains of a once-massive star that exploded as a powerful supernova at the end of its natural life.


Andromeda Galaxy scanned with high-energy X-ray vision

NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, has captured the best high-energy X-ray view yet of a portion of the Andromeda Galaxy, our nearest large neighbouring spiral galaxy. The space observatory has observed 40 “X-ray binaries” — intense sources of X-rays comprising a black hole or neutron star that feeds off a stellar companion.


Hubble’s Andromeda Galaxy survey unlocks clues to star birth

In a Hubble Space Telescope survey of 2,753 young, blue star clusters in the neighbouring Andromeda Galaxy (M31), astronomers have found that M31 and our own galaxy have a similar percentage of newborn stars based on mass. The intensive survey was a unique collaboration between astronomers and “citizen scientists,” volunteers who provided invaluable help in analysing the mountain of data from Hubble.
