About this Image

This is a VLA image of the galaxy M87, showing details of the large-scale, radio-emitting "bubbles" believed to be powered by the black hole at the galaxy's center. The galaxy's center (and the black hole) lie deep within the bright, reddish region in this image. The structure in this image is approximately 200,000 light-years across. This image was made at a radio wavelength of 90 centimeters.
