NuSTAR X-Ray Telescope Launched

NASA launched the Nuclear Spectroscopic Telescope Array, NuSTAR, satellite into Earth orbit to help find out what's left after a star explodes. NuSTAR's ability to focus hard X-rays will be used to inspect the surroundings of supernova remnants. This will help scientists better understand why these supernovas occurred and what types of objects resulted. It will also reveal the mechanisms that make their surroundings glow so hot.
