老鷹星雲與創生之柱
作品賞

第9屆科學攝影展 - 佳作
科學圖說

M16又名老鷹星雲,是一個位於巨蛇座的著名星雲。老鷹星雲最著名的特徵是「創生之柱」,哈伯太空望遠鏡於1995年拍攝的照片顯示出氣體和塵埃形成的巨大柱狀結構。在這些柱子內部和表面有新的恆星正在形成​。如今,即便透過現在的小型地面望遠鏡與影像處理技術,同樣可呈現創生之柱的風貌。柱子本身長約4光年,由冷的分子氫和塵埃組成,受到附近年輕恆星(如NGC 6611星團)的強烈紫外線輻射和恆星風的雕刻與侵蝕​。

Introduction

The famed Eagle Nebula, also cataloged as M16, is located in the constellation Serpens. The most well-known feature of the Eagle Nebula is its "Pillars of Creation." A 1995 image taken by the Hubble Space Telescope revealed these massive columns of interstellar gas and dust, within and on the surfaces of which new stars are actively forming. Today, modest ground-based telescopes for amateur astronomers, combined with modern image-processing techniques, can also reveal the Pillars of Creation in all their striking beauty. The pillars themselves are approximately four light-years long and composed of cool molecular hydrogen and dust. They are being sculpted and eroded by intense ultraviolet radiation and stellar winds from nearby young stars, such as those in the NGC 6611 star cluster.
