This artist's concept illustrates a supermassive black hole with millions to billions times the mass of our sun. Supermassive black holes are enormously dense objects buried at the hearts of galaxies.
This new view of spiral galaxy IC 342, also known as Caldwell 5, includes data from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. IC 342 lies 7 million light-years away in the Camelopardalis constellation.
This new view of the historical supernova remnant Cassiopeia A, located 11,000 light-years away, was taken by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. While the star is long dead, its remains are still bursting with action.
NASA's NuSTAR will be able to identify individual black holes making up the diffuse X-ray glow, also called the X-ray background. At bottom right is a simulated view of what NuSTAR will see.
First Look at Milky Way's Monster in High-Energy X-ray Light
These images, taken by NASA's black-hole hunter, NuSTAR, are the first, focused high-energy X-ray views of the area surrounding the supermassive black hole, called Sagittarius A*, at the center of our galaxy.
NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, mission is lowered into its shipping container at Orbital Sciences Corporation in Dulles, Va. It is scheduled to launch from Kwajalein Atoll in the Marshall Islands on March 14, 2012.
At Vandenberg Air Force Base's processing facility in California, the separation ring on the aft end of NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), at right, inches its way toward the third stage of an Orbital Sciences Pegasus XL rocket.
Inside an environmental enclosure at Vandenberg Air Force Base's processing facility in California, solar panels line the sides of NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), which was just joined to the Orbital Sciences Pegasus XL rocket.
Inside an environmental enclosure at Vandenberg Air Force Base's processing facility in California, technicians complete the final steps in mating NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and its Orbital Sciences Pegasus XL rocket.
Engineers in the final stages of assembling NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, at Orbital Sciences Corporation in Dulles, Va., January 2012.
A spacecraft technician is performing closeout work inside the fairing that will be installed around NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) spacecraft in a processing facility at Vandenberg Air Force Base in California.
NASA's NuSTAR has taken its first snapshots of the highest energy X-rays in the cosmos, the same kind used by doctors to take pictures of your bones. NuSTAR chose a black hole in the constellation Cygnus as its first target due to its brightness.
This is an artist's concept of NASA's NuSTAR spacecraft which has a 10-meter mast that deploys after launch to separate the optics modules (right) from the detectors in the focal plane (left).
An Orbital Sciences technician completes final checks of NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, before the Pegasus payload fairing is secured around it.
NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, has a complex set of mirrors, or optics, that will help it see high-energy X-ray light in greater detail than ever before.
This photo shows the Orbital Sciences Corporation Pegasus XL rocket with NASA's NuSTAR spacecraft after attachment to the L-1011 carrier aircraft known as 'Stargazer.'
