NGC 1333
Characteristics:
Magnitude: ? (faint)
Size: about 9'
Distance: ?
RA: 03h 29m 29s
Dec: 31 degrees 23' 07"
Description:
NGC 1333 is located
in the constellation Perseus and is a beautiful example of a reflection
nebula. Stars forming within this nebula are less than a million
years old, which is young by stellar standards. Blue light
emitted by the central star is preferentially scattered by surrounding
dust
(resulting in the characteristic blue color of the reflection
nebula). Focal patches of hydrogen gas in this region glow in
reddish-brown light, representing Ha emission induced by
ultraviolet radiation from nearby stars. Much of this
region is filled with dense dust that
obscures light from stars behind the nebula. Therefore,
like NGC 7023
and the Cocoon
Nebula, this region is comprised of all three main
nebulosities:
reflection, emission, and dark.
