Hubble Space Telescope Images of M87. At right, a large-scale image taken with the Wide-Field/Planetary Camera-2 from 1998 (NASA and the Hubble Heritage Team (STScI/AURA), J. A. Biretta, W. B. Sparks, F. D. Macchetto, E. S. Perlman). The two images at left show an image taken in 2006 with the Advanced Camera for Surveys’ High Resolution Channel. The position of the supermassive black hole is indicated by the black dot in the lower left panel, and a knot in the jet (HST-1), which was flaring in 2006, is also indicated on this panel. The red dot indicates the center of the galaxy’s light distribution, which is offset from the position of the black hole by 22 +/- 3 light years.
