OBJECT DESCRIPTION AND IMAGE SESSION

Commentary Globules are dynamic structures formed by cold molecular clouds and hot ionized stars. Typically the head of the globule face intense radiation stars and boils lower density gas and intense stellar winds. The winds are formed from the ionized stars that evaporate dust and gas away from the head. Most CG's are located in the Gum nebula, a large region of ionized gas with approximate distance and size of 450 and 300 pc, respectively. The head of the Commentary Globule is illuminated by a variable F2 IIIe star. The age and distance of this star and hence the Globule are still under discussion. 

 

CG1 (aka Be135) is located one degree east from L Puppis (Mg 2.6 - 6.2). A Constellations that gathers others CG objects. It is quite visible some reflection nebula in the head of the object coming out of the group of stars which apparently are very active.
