在银河系最亮的部分之一有一个星云，在那里发生了一些最奇怪的事情。NGC 3372被称为船底座大星云，是大质量恒星和不断变化的星云的家园。锁眼星云（NGC 3324），图像中心下方的明亮结构，容纳了几颗这样的大质量恒星。整个船底座星云，在这里被捕获，跨度超过300光年，位于船底座约7500光年远。船底二是星云中最具活力的恒星，在19世纪30年代曾是天空中最亮的恒星之一，但后来急剧褪色。虽然船底座埃塔本身可能处于超新星爆炸的边缘，但x射线图像表明，船底座大星云的大部分地区都是名副其实的超新星工厂。

In one of the brightest parts of Milky Way lies a nebula where some of the oddest things occur. NGC 3372, known as the Great Nebula in Carina, is home to massive stars and changing nebulas. The Keyhole Nebula (NGC 3324), the bright structure just below the image center, houses several of these massive stars. The entire Carina Nebula, captured here, spans over 300 light years and lies about 7,500 light-years away in the constellation of Carina. Eta Carinae, the most energetic star in the nebula, was one of the brightest stars in the sky in the 1830s, but then faded dramatically. While Eta Carinae itself maybe on the verge of a supernova explosion, X-ray images indicate that much of the Great Nebula in Carina has been a veritable supernova factory.
