Barnard 30 is a dark cloud in the Lambda Orionis ring, north of Lambda Orionis, also called Meissa.

[2] The Barnard 30 cloud is one of the regions in the Lambda Orionis Ring where the population of young stars is concentrated, together with the Lambda Orionis cluster and Barnard 35.

[2][5] The stellar population in Barnard 30 is about 2-3 million years old and is therefore significantly younger than the central Lambda Orionis cluster.

A possible supernova 1 million years ago that possibly has formed the Lambda Orionis ring might be an additional trigger for the star-formation in this region.

Because Barnard 30 shares the same constellation as the famous Orion Nebula it is rarely imaged.
