In the Core of the Carina Nebula

Explanation: What’s happening in the core of the Carina Nebula? Stars are forming, dying, and leaving an impressive tapestry of dark dusty filaments. The entire Carina Nebula, cataloged as NGC 3372, spans over 300 light years and lies about 8,500 light-years away in the constellation of Carina. The nebula is composed predominantly of hydrogen gas, which emits the pervasive red and orange glows seen mostly in the center of this highly detailed featured image. The blue glow around the edges is created primarily by a trace amount of glowing oxygen. Young and massive stars located in the nebula’s center expel dust when they explode in supernovas. Eta Carinae, the most energetic star in the nebula’s center, was one of the brightest stars in the sky in the 1830s, but then faded dramatically.

说明: 船底座星云的核心发生了什么事？恒星正在形成、死亡，并留下了吸睛的黝黑尘埃细丝织锦。跨幅有300多光年，位于船底座方向约8,500光年远处的船底座星云，亦名为NGC 3372。此星云的主成分是氢气，因此这幅极为细致的主题影像之中心附近，有无所不在的泛红和橙红氢辐射。而其周边的泛蓝辉光，主要源自微量的氧。此外，船底座星云中心的年轻大质量恒星，在发生超新星爆炸时会排放尘埃。海山二（Eta Carinae）是此星云中心最活跃的恒星，它在19世纪30年代，曾是天空中最明亮的恒星之一，不过后来急剧变暗。
