宽视场红外巡天探测器在西环星云分子云中发现了一群年轻的恒星天体（yso）。图像显示，yso主要分为两组，这两组与星云中的暗丝状结构相一致。光度分析显示有许多I类和II类天体。其中几个天体的位置被发现与已知的致密核心和CO流出相对应。I类天体倾向于密集聚集，II类天体在整个区域内分布更为均匀。
The Wide-field Infrared Survey Explorer has uncovered a population of young stellar objects (YSOs) in the Western Circinus molecular cloud. Images show the YSOs to be clustered into two main groups that are coincident with dark filamentary structure in the nebulosity. Analysis of photometry shows numerous Class I and II objects. The locations of several of these objects are found to correspond to known dense cores and CO outflows. Class I objects tend to be concentrated in dense aggregates, and Class II objects more evenly distributed throughout the region.
