Two actively forming stars are responsible for the shimmering hourglass-shaped ejections of gas and dust that gleam in orange, blue, and purple in this representative color image captured by NASA’s James Webb Space Telescope. This star system, called Lynds 483, is named for American astronomer Beverly T. Lynds, who published extensive catalogs of “dark” and “bright” nebulae in the early 1960s.
The two protostars are at the center of the hourglass shape, in an opaque horizontal disk of cold gas and dust that fits within a single pixel. Much farther out, above and below the flattened disk where dust is thinner, the bright light from the stars shines through the gas and dust, forming large semi-transparent orange cones.

两颗正在积极形成的恒星产生了闪烁的沙漏状气体和尘埃喷射,在这张由NASA詹姆斯·韦布太空望远镜拍摄的代表色图像中,它们呈现出橙色、蓝色和紫色的光辉。该恒星系统被称为林兹483(Lynds 483),以美国天文学家贝弗利·T·林兹(Beverly T. Lynds)的名字命名,他在20世纪60年代初期发表了关于“暗星云”和“亮星云”的星表。
这两颗原恒星位于沙漏形结构的中心,隐藏在一条由冷气体和尘埃组成的不透明水平盘中,该盘小到仅占图像的一个像素。而在更远处,在盘面上下方的区域,由于尘埃较为稀薄,恒星的强光能够穿透气体和尘埃,形成巨大的半透明橙色锥形结构。
