One or more eruptions from a black hole at the heart of this galaxy has created a dark "bubble" away from the galaxy's core, as shown in this combined image from two space telescopes. The bubble makes the galaxy resemble a teacup. The galaxy hosts a supermassive black hole that is pulling in material, which glows brightly before it spirals into the black hole. The hot material produces a lot of X-rays (blue), which are added to the optical view of the galaxy (red and green). [NASA/CXC/Univ. of Cambridge/G. Lansbury et al./STScI/W. Keel et al.]
