   Explanation: In the center of this serene stellar swirl is likely a
   harrowing black-hole beast. The surrounding swirl sweeps around
   billions of stars which are highlighted by the brightest and bluest.
   The breadth and beauty of the display give the swirl the designation of
   a [7]grand design spiral galaxy. The central beast shows evidence that
   it is a supermassive [8]black hole about 10 million times the mass of
   [9]our Sun. This ferocious creature [10]devours stars and gas and is
   surrounded by a spinning moat of hot plasma that [11]emits blasts of
   [12]X-rays. The central violent activity gives it the designation of a
   [13]Seyfert galaxy. Together, [14]this beauty and beast are cataloged
   as NGC 6814 and have been [15]appearing together toward the
   constellation of the Eagle ([16]Aquila) for roughly the past billion
   years.
