NGC 7380 (Wizard Nebula)
Characteristics:
RA: 21h 47m 21s
Dec: +58 degrees 07' 57"
PA: plus 228 degrees
Description:
NGC
7380 is a young star cluster born within the emission nebula SH2-142,
in the constellation
Cepheus. The shape of this region when presented vertically
resembles
a wizard with some imagination, but I preferred to orient it more
horizonally as shown above. Like many star forming regions, the
active
young stars emit UV radiation, which exites hydrogen atoms to emit in
the H alpha range (656nm, red), H beta (486 nm, blue), and is also
energetic enough to exite oxygen atoms (OIII, 496nm and 501nm,
blue-green).
The
central part of the nebula shows cleared out gas that is emitting more
H beta and OIII relative to H alpha, giving it a bluish appearance even
in this HaRGB image (taken without an OIII filter). Columns of
gas are
being
sculpted by UV winds from the hot, newly formed stars, demonstrating a
variety of "elephant trunk" shapes typical of other similar star
forming regions such as IC 1396 and
the Rosette
Nebula. More information about NGC 7380
may be found in Rob
Gendler's
website.
