Often overshadowed by the more popular Messier 13, M92 is rather bright and in a dark sky can sometimes be seen with the naked eye as a fuzzy dot. Along with a population of red giant stars it also seems to have an overabundance of blue stragglers. In the high resolution links below you can easily see all the tiny blue stars. Its 14 arc minutes in diameter and contains around 250,000 stars. Its one of the older globular clusters known with an estimated age of 14.2 billion years. M92 was discovered in 1777 by German Astronomer Johann Elert Bode.
