Streaming out from the center of the galaxy M87 like a cosmic searchlight is one of nature’s most amazing phenomena, a black-hole-powered jet of sub-atomic particles traveling at nearly the speed of light. In this Hubble Space Telescope image, the blue of the jet contrasts with the yellow glow from the combined light of billions of unseen stars and the yellow, point-like globular clusters that make up this galaxy.
