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
