The Lagoon Nebula
Situated some 5,000 light years away, the stellar nursery of the Lagoon Nebula lies in the constellation of Sagittarius. Despite being light years away, the Lagoon Nebula is in fact one of the few star-forming nebulae that it is possible to see with the naked eye (in optimum conditions) from mid-northern latitudes.
