NuSTAR Bringing the High Energy Universe into Focus

 

Black Holes Shine for NuSTAR

B-nustar-blackhole

An optical color image of galaxies is seen here overlaid with X-ray data (magenta) from NASA's Nuclear Spectroscopic Telescope Array (NuSTAR).

NuSTAR's serendipitous discovery in this field lies to the left of a galaxy, called IC 751, at which the telescope originally intended to look. Both magenta blobs show X-rays from massive black holes buried at the hearts of galaxies.

The optical image is from the Sloan Digital Sky Survey and a color composite of images over three different optical wavebands (the G, R, and I bands). The NuSTAR data shows X-rays in the 3 to 24 keV energy range.
