星尘云在850光年外的英仙座分子云中飘过。尘埃星云反射嵌入的年轻恒星发出的光，在近4度的宽视场中十分突出。星云ngc1333以其特有的蓝色反射在中心附近突出。赫比格-哈罗天体发出的对比鲜明的红色辐射，以及新近形成的恒星发出的喷流和受冲击的发光气体，散布在布满尘埃的广阔空间中。虽然许多恒星正在分子云中形成，但大多数恒星在可见波长上被无处不在的尘埃遮挡。NGC 1333周围的混乱环境可能类似于45亿年前我们的太阳形成的环境。以英仙座分子云的估计距离计算，这幅宇宙景象的跨度约为80光年。成长画廊：彗星ATLAS （G3）

Clouds of stardust drift through this deep skyscape, across the Perseus molecular cloud some 850 light-years away. Dusty nebulae reflecting light from embedded young stars stand out in the nearly 4 degree wide field of view. With a characteristic bluish color reflection nebula NGC 1333 is prominent near center. Hints of contrasting red emission from Herbig-Haro objects, the jets and shocked glowing gas emanating from recently formed stars, are scattered across the dusty expanse. While many stars are forming in the molecular cloud, most are obscured at visible wavelengths by the pervasive dust. The chaotic environment surrounding NGC 1333 may be similar to one in which our own Sun formed over 4.5 billion years ago. At the estimated distance of the Perseus molecular cloud, this cosmic scene would span about 80 light-years. Growing Gallery: Comet ATLAS (G3)
