The formation of the Lagoon Nebula is a long-standing mystery of astronomy. Situated about 3,800 light years from Earth, the nebula is a stellar nursery where stars of high mass and luminosity are being born. The hottest and brightest stars in the region influence surrounding gas clouds, making them glow in classic Òemission nebulaÓ style. SALT may help astronomers learn how the nebula was formed.
