   Explanation: A broad expanse of glowing gas and dust presents a
   bird-like visage to astronomers from planet Earth, suggesting its
   popular moniker - The Seagull Nebula. Using narrowband image data, this
   3-panel mosaic of the cosmic bird covers a 2.5 degree swath across the
   plane of the Milky Way, near the direction of Sirius, alpha star of the
   constellation Canis Major. Likely part of a larger shell structure
   swept up by successive supernova explosions, the broad Seagull Nebula
   is cataloged as Sh2-296 and IC 2177. The prominent bluish arc below and
   right of center is a bow shock from runaway star FN Canis Majoris. This
   complex of gas and dust clouds with other stars of the Canis Majoris
   OB1 association spans over 200 light-years at the Seagull Nebula's
   estimated 3,800 light-year distance.
