NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR ) satellite observatory has detected “high energy” x-rays from 5 galactic supermassive black holes. By aiming NuSTAR at nine potential “black hole” galaxies, scientists detected five massive black holes previously obstructed by gas/dust clouds.

Launched in 2012, NuSTAR is able to detect higher energy x-rays than previous satellites. Now researchers seem to have evidence backing the theory – countless black holes litter the universe, obstructed by clouds of cosmic interference. On July 6, 2015 findings were presented to the Royal Astronomical Society’s National Astronomy Meeting in Wales. Head researcher George Lansbury said….
“For a long time we have known about supermassive black holes that are not obscured by dust and gas, but we suspected that many more were hidden from our view.
Thanks to NuSTAR for the first time we have been able to clearly see these hidden monsters that are predicted to be there, but have previously been elusive because of their ‘buried’ state.
Although we have only detected five of these hidden supermassive black holes, when we extrapolate our results across the whole Universe then the predicted numbers are huge and in agreement with what we would expect to see.”
