Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Westerlund 1 is a compact young star cluster in the Milky Way galaxy, about 3.5–5 kpc away from Earth. In fact, it is the most massive compact young star cluster known in the entire Local Group of galaxies. It was discovered by Bengt Westerlund in 1961 but remained largely unstudied for many years due to high interstellar extinction (absorption) in its direction. The cluster contains a large number of rare, evolved, high-mass stars, including: 6 yellow hypergiants, 4 red supergiants, 24 Wolf-Rayet stars, a luminous blue variable, many OB supergiants, and an unusual sgB[e] star which has been proposed to be the remnant of a recent stellar merger.
