Description

RCW 36 (also designated Gum 20) is an emission nebula containing a open cluster in the constellation Vela. This H II region is part of a larger-scale star-forming complex known as the Vela Molecular Ridge (VMR), a collection of molecular clouds in the Milky Way that contain multiple sites of ongoing star-formation activity The VMR is made up of several distinct clouds, and RCW 36 is embedded in the VMR Cloud C.

RCW 36 is one of the sites of massive-star formation closest to our Solar System whose distance of approximately 700 parsecs (2300 light-years). The most massive stars in the star cluster are two stars with late-O or early-B spectral types, but the cluster also contains hundreds of lower-mass stars This region is also home to objects with Herbig–Haro jets, HH 1042 and HH 1043
