Westerlund 1
Westerlund 1 (abbreviated Wd1, sometimes called Ara Cluster) is a compact young super star cluster about 3.8 kiloparsec, kpc (12,000 ly) away from Earth. It is thought to be the most massive young star cluster in the Milky Way, and was discovered by Bengt Westerlund in 1961 but remained largely unstudied for many years due to high interstellar extinction, interstellar absorption in its direction. In the future, it will probably evolve into a globular cluster. The cluster contains a large number of rare, evolved, high-mass stars, including: 6 yellow hypergiants, 4 red supergiants including Westerlund 1-26, one of the List of largest known stars, largest known stars, 24 Wolf-Rayet stars, a luminous blue variable, many OB star, OB supergiants, and an unusual supergiant B(e) star, sgB[e] star which has been proposed to be the remnant of a recent Stellar collision, stellar merger. In addition, X-ray observations have revealed the presence of the anomalous X-ray pulsar CXOU J164710.2- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
