I (and members of my group) spend a lot of time thinking about the supermassive black hole in the center of our Galaxy, Sgr A* (see recent group blog post, for instance). The new hard X-ray imaging mission NuSTAR has just released a really cool series of images showing a hard X-ray flare from Sgr A*! We have also been monitoring Sgr A* as part of our Chandra X-ray Visionary Program and even caught another flare recently at the same time as them!
