Associate Professor David Ballantyne is on the science team for NuSTAR, a telescope that NASA launched in June 2012. Ballantyne helped plan the mission, which looks at black holes in ways never seen before. NASA has now released some of the instrument's newest findings. NuSTAR has watched a black hole's gravity pull X-ray light, stretching and blurring that light. Black hole experts like Ballantyne have observed this phenomenon before, but never in so much detail.
