Explanation: With natal dust clouds in silhouette against glowing atomic gas, this colorful and chaotic vista lies within one of the largest star forming regions in the Milky Way galaxy, the Great Carina Nebula. The telescopic close-up frames a field of view about 80 light-years across, a little south and east of Eta Carinae, the nebula’s most energetic and enigmatic star. Captured under suburban skies improved during national restrictions, a composite of narrowband image data was used to create the final image. In it, characteristic emission from the nebula’s ionized sulfur, hydrogen, and oxygen atoms is mapped to red, green, and blue hues, a color palette also popular in Hubble Space Telescope images. The celestial landscape of bright ridges of emission bordered by cool, obscuring dust lies about 7,500 light-years away toward the southern constellation Carina.

说明: 在银河系最大恒星形成区之一的船底座大星云内,这片色彩缤纷而混乱的视野里,散布着许多以剪影之姿出现在辉光原子气体前方的胎衣云。这幅望远镜特写影像,涵盖了海山二这颗此星云最活跃和神秘的恒星,东南嵎一片约80光年宽的区域。上面这幅影像,是在阿根廷全国限制迁移期间,由摄于郊区的一批窄波段影像数据组合而成。在影像中,来自星云电离硫、氢和氧原子的特征辐射,依照哈勃太空望远镜影像常用的色表,分别染成红、绿和蓝等色泽。这片明亮辐射脊有低温黝黑尘埃为伴的星野,位在南天的船底座方向,约7,500光年远之处。
