emission nebula in the constellation of Cepheus.
This image, spanning about 2 x 1.5
degrees of arc (4 x 3 Moon apparent diameters) is
only the central part of a much larger cloud
containing giant Wolf Rayette and other hot young
These stars are irradiating the cloud,
ionising the gasses which then re-radiate
strong light emissions.
These emissions include the sulphurII,
hydrogenII and oxygen III that are depicted
in this false colour image created in the Hubble SHO
Natural star coloring has been applied to the stars
for cosmetic effect.
