NASA's NuSTAR Helps Solve Riddle of Black Hole Spin Two X-ray
space observatories, NASA's NuSTAR and ESA's XMM-Newton, have
teamed up to measure definitively, for the first time, the spin
rate of a black hole. NuSTAR is now in orbit, taking focused
images of the high-energy X-ray sky. To see what NuSTAR has and
will be looking at, go to the NuSTAR Science Operations Center
website. NASA Hosts Media Teleconference About Black Hole
