是什么引起了蝌蚪星云的骚动？恒星的形成。蝌蚪星云IC 410的尘埃辐射，位于约12000光年外的御夫座（御夫座）北部。这团发光的气体云直径超过100光年，由内嵌的疏散星团NGC 1893的恒星风和辐射雕刻而成。形成于400万年前的星际云中，明亮的新形成的星团在恒星形成的星云周围随处可见。值得注意的是，在这张特色图像的右下方，有两条相对密集的物质飘带，它们从星云的中心区域尾随而去。IC 410可能是正在形成恒星的地方，这些宇宙蝌蚪状的形状大约有10光年长。这张照片经过处理，突出显示了硫（红色）、氢（绿色）和氧（蓝色）气体的排放，但用数字技术删除了恒星。

What's causing the commotion in the Tadpole Nebula? Star formation. Dusty emission in the Tadpole Nebula, IC 410, lies about 12,000 light-years away in the northern constellation of the Charioteer (Auriga). The cloud of glowing gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893. Formed in the interstellar cloud a mere 4 million years ago, bright newly formed cluster stars are seen all around the star-forming nebula. Notable on the lower-right of the featured image are two relatively dense streamers of material trailing away from the nebula's central regions. Potentially sites of ongoing star formation in IC 410, these cosmic tadpole shapes are about 10 light-years long. The image was processed highlighting the emission from sulfur (red), hydrogen (green), and oxygen (blue) gas -- but with the stars digitally removed.
