Cygnus A

At 600 million light years is Cygnus A, known to be one of the issuers of our strongest X-ray sky.

In the picture, what you see is a composite of X-ray and radio emissions (blue and red, exactly). Radio broadcasts are a low frequency (red) and are of 300 thousand light years wide (cool, huh?).

At the center of Cygnus A white area corresponding to the black hole series that comes standard on all galaxies (if a galaxy Cygnus A) is observed.
