Summary
"Sequence of Hubble images showing apparent motion at six times the speed of light in the galaxy M87. TOP PANEL: Hubble image showing jet streaming out from the galaxy's nucleus [bright round region at far left]. The jet is about 5000 light years long, and the box indicates where the superluminal motions were seen. BOTTOM PANEL: Sequence of Hubble images showing motion at six times the speed of light. The slanting lines track the moving features, and the speeds are given in units of the velocity of light ``c." The images were made between 1994 and 1998 with the Faint Object Camera on the Hubble Space Telescope. PHOTO CREDIT: John Biretta, Space Telescope Science Institute."
