“Images from three Nasa telescopes seem to have unearthed a scowling eye in deep space – but it’s actually a nearby galaxy – NGC 4151 – with gas interacting with the growing black hole at its center. The white ‘pupil’ is the black hole – and the red ‘brow’ is hydrogen, a gravity-warped structure at the galaxy’s heart that includes material falling towards its center. The blue is X-rays which scientists are studying to understand how such black holes interact with the gas around them. ‘It looks like a really evil eye to me,’ the blog Gizmodo said this week. ‘It’s a photo of the central region of NGC 4151, a spiral galaxy 43 millions light years away from Earth.” w/ photo
