Vela Supernova Remnant
Credit & Copyright: Robert Gendler Explanation: The plane of our Milky Way Galaxy runs through this complex and beautiful skyscape. At the northwestern edge of the constellation Vela (the Sails) the 16 degree wide, 30 frame mosaic is centered on the glowing filaments of the Vela Supernova Remnant, the expanding debris cloud from the death explosion of a massive star. Light from the supernova explosion that created the Vela remnant reached Earth about 11,000 years ago. In addition to the shocked filaments of glowing gas, the cosmic catastrophe also left behind an incredibly dense, rotating stellar core, the Vela Pulsar. Some 800 light-years distant, the Vela remnant is likely embedded in a larger and older supernova remnant, the Gum Nebula. The broad mosaic includes other identified emission and reflection nebulae, star clusters, and the remarkable Pencil Nebula.

说明: 我们银河系的盘面穿过这片既美丽又复杂的星野。这张跨幅达16度，由三十张照片组合出来的影像，呈现了船帆座西北角的星场，中心区的光亮云气丝则是船帆座超新星遗骸，为一颗大质量爆炸死亡后所留下的扩张碎片云。大约在一万一千年前，产生船帆座遗骸的超新星爆炸之闪光传到地球。这次的爆炸，除了激震诱发出光亮的云气丝外，也留了一颗密度超高、快速旋转的核心--船帆座波霎。离我们大约八百光年远的船帆座遗骸，很可能是包在另一个更大更老的超新星遗骸 (甘姆星云)之内。这张广角的组合影像，也呈现了数个已被编录的发射和反射星云、星团和神奇的铅笔星云。
