M16 and the Eagle Nebula

M16 和老鹰星云

A star cluster around 2 million years young surrounded by natal clouds of dust and glowing gas, M16 is also known as The Eagle Nebula. This beautifully detailed portrait of the region was made with groundbased narrow and broadband image data. It 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 at lower left 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).

M16 是一个大约 200万年年轻的星团,被尘埃和发光气体的本命云包围,也被称为鹰星云。这个美丽而详细的地区肖像是用地面窄和宽带图像数据制作的。它包括由哈勃太空望远镜拍摄的著名的宇宙雕塑。被描述为大象的树干或创造的支柱,中心附近升起的密集、尘土飞扬的柱子长度为光年,但在引力上收缩形成恒星。来自星团的高能辐射侵蚀了尖端附近的物质,最终暴露了嵌入的新恒星。从左下角的明亮发射脊延伸而来的是另一个尘土飞扬的恒星形成柱,被称为鹰之仙女星云。M16 位于大约 7,000 光年之外,是双筒望远镜或小型望远镜的一个容易的目标,该望远镜位于天空富含星云的部分,朝向分裂的蛇尾星座 (蛇的尾巴)。
