NotesAn emission nebula in the direction of the Galaxy's core, the Lagoon acts as a stellar nursery. Dark material within the main nebula forms a distinct twisted shape known as the Hourglass.

A nebulous region roughly five thousand light years from the Solar System, in the direction of the Milky Way's core. More than a hundred light years from end to end, several new stars are forming within the matter that makes up the nebula. Forces from one brilliant new star that has already formed within the nebula generate a distinct structure within the heart of the cloud, sometimes referred to as the Hourglass.
