船底座星云的核心发生了什么？恒星形成，死亡，留下令人印象深刻的暗尘细丝织锦。整个船底座星云，编号为NGC 3372，跨度超过300光年，位于船底座约8500光年远的地方。该星云主要由氢气组成，它散发出无处不在的红色和橙色光芒，这些光芒主要出现在这张非常详细的特色图像的中心。边缘周围的蓝光主要是由微量的发光氧产生的。位于星云中心的年轻大质量恒星在超新星爆炸时喷出尘埃。船底二是星云中心最具活力的恒星，在19世纪30年代是天空中最亮的恒星之一，但后来急剧褪色。你的天空惊喜：APOD在你的生日上展示了什么照片？(1995后)

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.
