- Cygnus_OB2 abstract "Cygnus OB2 is an OB association that is home to some of the most massive and most luminous stars known, including Cyg OB2 #8 and Cyg OB2 #12. It also includes one of the largest known stars, NML Cygni. The region is embedded within a wider region of star formation known as Cygnus X, which is one of the most luminous objects in the sky at radio wavelengths. The region is approximately 4,700 light years from Earth in the constellation of Cygnus.The young cluster is one of the largest known, and the largest in the northern hemisphere with some authors classifying it as a young globular cluster similar to those present in the Large Magellanic Cloud. Although it is over ten times more massive than the famous Orion Nebula, Cygnus OB2 is much less well known due to its location behind a massive dust cloud known as the Cygnus Rift, which obscures many of the stars in it; this means that, despite the consensus of its large size, it's hard to determine its actual properties with its estimated number of massive stars ranging, according to different scientists, for example, from 50 to 100 of spectral type O and its total mass having been calculated as (4-10)*104 or 3*104 solar masses according to other investigations.Despite this, recent surveys ranging from radio to X-ray wavelengths have observed the region to incredible depths in an attempt to gain a better understanding of how the processes of star and planet formation occur on such large scales, compared to the small scales of nearby regions. These studies include observations with some of the world's premier astronomical observatories including the Chandra X-ray Observatory, Spitzer Space Telescope, the Herschel Space Observatory and the Gran Telescopio Canarias.Other noteworthy stars, not included in the Massey et al paper, include BD+40° 4210, a blue supergiant and Luminous blue variable candidate, as well as the massive runaway star BD+43° 3654.".
