Jets of energetic particles (pink and red) shoot into space from near the black hole in the center of M84 in this image, which combines observations from optical, radio, and X-ray telescopes. The jets heat surrounding clouds of gas (blue) to millions of degrees, preventing gas clouds from collapsing to form new stars. The jets span tens of thousands of light-years, and squirt into space at close to the speed of light. [NASA/CXC/MPE/A.Finoguenov et al.; NSF/NRAO/VLA/ESO/R.A.Laing et al; SDSS]
