Chandra X-ray Image of MS 0735.6+7421
The Chandra image of galaxy cluster MS 0735.6+7421 shows diffuse, nearly 50-million-degree gas that permeates the space between the galaxies. The X-ray data show enormous holes, or cavities, in the gas that are filled with charged particles spiraling around magnetic field lines. The cavities were created by jets of charged particles ejected at nearly light speed from a supermassive black hole a billion times the Sun's mass in the bright central galaxy.

Hubble Optical Image of MS 0735.6+7421
Galaxy cluster MS0735.6+7421 is located about 2.6 billion light-years away in the constellation Camelopardus. The optical view of the galaxy cluster, taken by the Hubble Space Telescope's Advanced Camera for Surveys in February 2006, shows dozens of galaxies bound together by gravity.

VLA Radio Image of MS 0735.6+7421
The Chandra X-ray image above shows enormous holes or cavities in the gas of the galaxy cluster MS 0735.6+7421, each roughly 640,000 light-years in diameter -- nearly seven times the diameter of the Milky Way. The cavities are filled with charged particles gyrating around magnetic field lines and emitting radio waves, as shown in this image taken with the Very Large Array telescope in New Mexico in June 1993.
