Globular star cluster M55 (NGC 6809), infrared image. These star clusters are dense spherical collections of stars; they can contain hundreds of thousands stars within a volume only a few hundred light years across. They formed billions of years ago in the early history of the galaxy. M55 is around 17,000 light years away, in the constellation of Sagittarius. This image was obtained with the VIRCAM (VISTA Infrared Camera) instrument on the VISTA (Visible and Infrared Survey Telescope for Astronomy) telescope at ESO's Paranal Observatory. Image published in 2012.
