The density of the cluster is probably one star per cubic light year. Globulars are found quite far from the centers of galaxies and some are believed to drift away from their galaxies and wander inter-galactic space. The manner in which globular clusters came to be formed is not well understood. The star Albireo, also known as Beta Cygni, is considered one of the most beautiful double stars in the sky. They lie about 410 light years away.
Different observers tend to describe the colors differently.
Gravity pulls the gas together, then the tremendous pressures cause the hydrogen to ignite, and a star is born. Due to its low position in the sky, light pollution and haze often interefere with our ability to get a good view of this nebula. However, it still ranks just behind M42 among the diffuse nebulae as one of the most inspiring sights. It lies at a distance of 2.2 million light years from us, has a diameter of 180,000 light years, and is estimated to contain about 300 billion stars. It's one of the largest galaxies known.
