The most conspicuous of the Pleiades reflection nebulae is NGC 1435 around
Merope, also called "Tempel's Nebula". This is the only one which was known
to John Herschel when he compiled his General Catalog (GC) in 1864, and has
been assigned the number GC 768. It has a faint extension, IC 349, which is
very small and 36" south following (east) of Merope.
Another diffuse nebula, IC 353, is about 1 degree north following of the
Pleiades, according to the Sky Catalog 2000. The present author has no
information if this nebula is associated with the Pleiades or their
nebulosity. Near the boundary of the Pleiades, but with no evidence for a
connection, lies the diffuse nebula IC 1990, which surrounds the double star
ADS 2799 (A: 5.9 m, B: 6.3 m, separation 0.4"), see e.g. Vehrenberg's Atlas
of Deep Sky Splendors..
Map of the Pleiades Star Cluster M45


In Greek mythology, the Pleiades were seven sisters. Their names were Maia,
Electra, Alcyone, Taygete, Asterope, Celaeno, and Merope. Their parents were
the Titan Atlas and the Oceanid, Pleione. One day while traveling, the
Pleiades and their mother met the giant hunter Orion.
He fell in love with the young women and started to pursue them. After being
chased for years, Zeus changed them into doves to help them escape. They
flew into the sky to become the cluster of stars in the constellation Taurus
the Bull.
However, only six stars are visible in the sky without a telescope. The
ancient Greeks explained the absence of a seventh star with several
different stories. According to one story, all the Pleiades consorted with
gods except Merope. Merope deserted her sisters because she was ashamed of
having a mortal husband, Sisyphus.
Another explanation is related to the myth of the Pleiad Electra who is
considered the ancestress of the royal house of Troy. The Greeks believed
that Electra abandoned her sisters in despair and transformed herself into a
comet when the city of Troy was destroyed. These legends seem to be
confirmed by a scientific finding according to which a seventh star in the
group of the Pleiades became extinct toward the end of the second millennium
BC.
