X-ray, Optical & Infrared Images of Cygnus OB2
These images of the star cluster Cygnus OB2 show X-rays from Chandra, infrared data from Spitzer, and optical emission from the Isaac Newton Telescope. Astronomers would like to better understand how this and other star factories like it form and evolve. Deep observations with Chandra have been used to detect the hot outer atmosphere for young stars in such clusters. Cygnus OB2 is the closest massive star cluster to Earth, and Chandra's observations revealed almost 1,500 X-ray sources there. Astronomers think these young stars in Cygnus OB2 range in age from one million to seven million years.
