Open star cluster Messier 34 (M34, NGC 1039) is an intermediate aged
open cluster of about 100 stars (according to H.S. Hogg), and lies
about 1,400 light years and is scattered over 35 arc minutes, more than
the diameter of the full Moon. This angular diameter corresponds to a
linear 14 light years.
The age of M34 is estimated at 180 million years, according
to new calculations of G. Meynet's Geneva Team.
M34 was probably first found by Giovanni Batista Hodierna before 1654,
and independently rediscovered by Charles Messier in on August 25, 1764.
Open cluster M34 can quite easily be found (even with the naked eye
under good conditions as a faint nebulous patch) as it lies just north
of the line from Algol (Beta Persei) to Gamma Andromedae. It is
resolved into stars even in 10x50 binoculars, and best at low
magnifications in telescopes.
