Also known as NGC 6523 or the Lagoon Nebula, Messier 8 is a giant cloud of gas and dust where stars are currently forming. At a distance of about 4,000 light years from Earth, Messier 8 provides astronomers an excellent opportunity to study the properties of very young stars. Many infant stars give off copious amounts of high-energy light including X-rays, which are seen in the Chandra data (pink). The X-ray data have been combined with an optical image of Messier 8 from the Mt. Lemmon Sky Center in Arizona (blue and white). Wishing everyone a very happy #spacesaturday!
