      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

   Explanation: Astronomers believe they have now found the most powerful
   example of a black hole outburst yet seen in our Universe. [7]The
   composite, false-color [8]featured image is of a [9]cluster of galaxies
   in the constellation of [10]Ophiuchus, the serpent-bearer. The
   composite includes [11]X-ray images (from the [12]Chandra X-ray
   Observatory and [13]XMM-Newton) in purple, and a [14]radio image (from
   India's [15]Giant Metrewave Radio Telescope) in blue (along with an
   [16]infrared image of the galaxies and stars in the field in white for
   good measure). The dashed line marks the border of a [17]cavity blown
   out by the [18]supermassive black hole which lurks at the center of the
   galaxy marked by the cross. [19]Radio emission fills this cavity.
   [20]This big blowout is believed to be due to the [21]black hole eating
   too much and experiencing a transient bout of "black hole nausea",
   which resulted in the ejection of a [22]powerful radio jet blasting
   into intergalactic space. The amount of energy needed to blow this
   cavity is equivalent to about [23]10 billion supernova explosions.
