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

The results will ultimately help researchers better understand the role of X-ray binaries in the evolution of our universe. According to astronomers, these energetic objects may play a critical role in heating the intergalactic bath of gas in which the very first galaxies formed...

Using NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) satellite observatory, the team detected the high-energy x-rays from 5 supermassive black holes previously clouded from direct view by dust and gas. The research, led by astronomers at Durham University, UK, supports the theory that potentially millions more supermassive black holes exist in the Universe, but are hidden from view.

The scientists pointed NuSTAR at 9 candidate hidden supermassive black holes that were thought to be extremely active at the centre of galaxies, but where the full extent of this activity was potentially obscured from view...

Using NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) satellite observatory, a Durnham University team detected high-energy xrays from 5 supermassive black holes previously clouded from direct view by dust and gas. It supports the theory that potentially millions more supermassive black holes exist in the Universe, but are hidden from view.
