This object is a billowing tower of cold gas and dust rising from a stellar nursery called the Eagle Nebula. 7,000 light-years distant from us, the soaring tower is 9.5 light-years or about 90 trillion kilometers tall. When Swiss astronomer Philippe Loys de Chéseaux discovered the Eagle Nebula in the mid-eighteenth century, he only described the cluster of stars surrounding it. Charles Messier independently rediscovered it in 1764 as part of his catalog, dubbing it M16.

According to Marcel Griaule's books Conversations with Ogotemmêli and The Pale Fox they knew about the fifty-year orbital period of Sirius and its companion prior to western astronomers.
