梅西耶16 (M16)是一个年轻约200万年的星团,周围环绕着尘埃和发光的气体云,也被称为鹰状星云。这张精美细致的区域图像采用了哈勃色彩斑斓的调色板,其中包括因哈勃太空望远镜拍摄的恒星形成复合体特写而闻名的宇宙雕塑。被描述为象鼻或创造之柱,在中心附近升起的密集的尘埃柱有光年长,但在引力作用下收缩形成恒星。来自星团恒星的高能辐射侵蚀了尖端附近的物质,最终暴露出嵌入其中的新恒星。从中心左侧的明亮发射脊延伸出来的是另一个尘埃恒星形成柱,被称为鹰状星云的仙女。M16距离我们大约7000光年远,是双筒望远镜或小型望远镜在天空中朝向分裂的尾蛇星座(蛇的尾巴)的星云丰富部分的一个容易的目标。这幅鹰状星云的望远镜图像,直径约70光年。

A star cluster around 2 million years young surrounded by natal clouds of dust and glowing gas, Messier 16 (M16) is also known as The Eagle Nebula. This beautifully detailed image of the region adopts the colorful Hubble palette and includes cosmic sculptures made famous in Hubble Space Telescope close-ups of the starforming complex. Described as elephant trunks or Pillars of Creation, dense, dusty columns rising near the center are light-years in length but are gravitationally contracting to form stars. Energetic radiation from the cluster stars erodes material near the tips, eventually exposing the embedded new stars. Extending from the ridge of bright emission left of center is another dusty starforming column known as the Fairy of Eagle Nebula. M16 lies about 7,000 light-years away, an easy target for binoculars or small telescopes in a nebula rich part of the sky toward the split constellation Serpens Cauda (the tail of the snake). As framed, this telescopic portrait of the Eagle Nebula is about 70 light-years across.
