M 30 - NGC 7099

M30 (NGC 7099) is a globular cluster of stars[1] located in the constellation of Capricornus approximately 27,000 light years from the Earth[1].  Globular clusters are usually comprised of very old stars, however, some of these stars have regained a "youthful" appearance and are known as "blue stragglers"[2].  This process can happen in two ways[2].  Blue stragglers can result from the collision of two stars or they may form in a close binary system where one star siphons hydrogen gas from its companion.  M30 is following a retrograde orbit through the Milky Way's inner halo suggesting that it was acquired from a satellite galaxy and not formed in our home galaxy[1}
