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.
This portrait
of the cosmic bird covers a 1.6 degree wide swath
across the plane of the Milky Way,
near
the direction of Sirius, alpha
star of the constellation Canis Major.
Of course, the
region includes objects with other
catalog
designations: notably
NGC 2327,
a compact, dusty emission region
with an embedded massive star that forms the bird's head
(aka the Parrot Nebula, above center).
Dominated by the
reddish glow of atomic hydrogen,
the complex of gas and dust clouds with bright
young stars spans over 100 light-years at an estimated
3,800 light-year distance.
