M8 Lagoon Nebula

The Laguna Nebula (also known as Messier 8, Messier 8, M8 or NGC 6523), is an emission nebula (specifically it is a Region H II) located in the constellation of Sagittarius. It is approximately 5,000 light-years away. It was discovered by Guillaume Le Gentil in 1747.

The nebula appears to have a depth comparable to its width and includes a number of Bok globules, some of which have been catalogued by Edward Emerson Barnard as B88, B89, and B296. The discovery of five Herbig-Haro objects at the southern edge of the nebula (HH893, HH894, HH895, HH896, and HH897) provides further evidence for ongoing star formation.

In the brightest portion of the nebula is a structure known as The Hourglass, in which intense star-forming activity occurs; there, in 2006, they identified four Herbig-Haro objects: HH867, HH868, HH869 and HH870.

It also includes a tornado-shaped dust structure caused by the action of ionizing radiation from the multiple star of spectral type O Herschel 36.
