The Milky Way Galaxy contains many different kinds of objects.
Globular star clusters are among my favorite in the galactic
zoo. Globular clusters are tightly packed with several hundred
thousands of stars. They are always far from the disk of the
galaxy. This is in stark contrast to open/galactic star clusters
such as . M13 Contains nearly half a million stars in an area
about 150 light years across. It is 26,000 light years away in
the constellation Hercules, and is one of many globular star
clusters that orbit around the Milky Way galaxy. The stars of
Globular clusters are 10 to 12 billion years old, and are
thought to be the first stars to form during the formation of
the Milky Way galaxy. As seen in the picture taken at the Round
Hill Observatory in Greenwich, the stars in the center of M13
are VERY close. They are in fact 500 times closer to each other
than the stars near our Sun. The nearest star to our Sun is over
4 light years away, but there are over 100 stars inside a cube 3
light years wide in the
