Because they are very dense, the gravitational pull of black holes is so strong that nothing can escape, not even light. Thus they have long remained black and mysterious. But now, thanks to ESA's and NASA's X-ray observatories, XMM-Newton and Chandra, astronomers have a much clearer picture of where black holes are and what they can actually do. And that can be quite dramatic! Observations of RXJ 12 42 11 have provided evidence of how a giant black hole can tear apart and swallow a star, as explained by Dr Stefanie Komossa of Max Planck institute.2004, 4.56 mins
