NuSTAR

Bringing the High Energy Universe into Focus

About the Mission
The NuSTAR (Nuclear Spectroscopic Telescope Array) mission has deployed the first orbiting telescopes to focus light in the high energy X-ray (3 - 79 keV) region of the electromagnetic spectrum. Our view of the universe in this spectral window has been limited because previous orbiting telescopes have not employed true focusing optics, but rather have used coded apertures that have intrinsically high backgrounds and limited sensitivity.
