From wikipedia: The nebula contains a number of Bok globules (dark, collapsing clouds of protostellar material), the most prominent of which have been catalogued by E.E. Barnard as B88, B89 and B296. M8 also includes a funnel-like structure caused by a hot O-type star that emits UV light, heating and ionizing gases on the surface of the nebula. The bright open cluster near the center of M8 is cataloged as NGC 6530

Distance: ~5,000 light years
