NASA's black-hole-hunter spacecraft, the Nuclear Spectroscopic Telescope Array, or NuSTAR, has "bagged" its first 10 supermassive black holes, like the ones pictured in this photo released recently. The mission, which has a mast the length of a school bus, is the first telescope capable of focusing the highest-energy X-ray light into detailed pictures..The new black-hole finds are the first of hundreds expected from the mission over the next two years. An optical color image of galaxies is seen here overlaid with X-ray data (magenta) from NuSTAR. The serendipitous discovery in this field, indicated by the arrow, lies to the left of a galaxy, called IC751, at which the telescope originally intended to look. Both magenta blobs show X-rays from massive black holes buried at the hearts of galaxies..UPI/ NASA/JPL-Caltech
