In this NASA/ESA Hubble Space Telescope image, Hubble once again lifts the veil on a famous — and frequently photographed — supernova remnant: the Veil Nebula. The remnant of a star roughly 20 times as massive as the Sun that exploded about 10,000 years ago, the Veil Nebula is situated about 2,400 light-years away in the constellation Cygnus. Hubble images of this photogenic nebula were first taken in 1994 and 1997, and again in 2015.
This view combines images taken in three different filters by Hubble’s Wide Field Camera 3, highlighting emission from hydrogen, sulfur, and oxygen atoms. The image shows just a small fraction of the Veil Nebula; if you could see the entire nebula without the aid of a telescope, it would be as wide as six full Moons placed side-by-side.
Although this image captures the Veil Nebula at a single point in time, it helps researchers understand how the supernova remnant evolves over decades. Combining this snapshot with Hubble observations from 1994 will reveal the motion of individual knots and filaments of gas over that span of time, enhancing our understanding of this stunning nebula.

在这张由NASA/ESA哈勃太空望远镜拍摄的图像中，哈勃再次揭开了一颗著名且经常被拍摄的超新星遗迹——面纱星云的神秘面纱。面纱星云是大约10,000年前爆炸的一颗质量约为太阳20倍的恒星遗迹，位于天鹅座，距离地球约2,400光年。哈勃最早在1994年和1997年拍摄了这片引人注目的星云，并在2015年再次进行观测。
该图像结合了第三代广域照相机使用三种不同滤光片拍摄的数据，突出显示了氢、硫和氧原子的发射光。这张照片仅展示了面纱星云的一小部分，如果能够用肉眼直接观测整个星云，它的宽度将相当于六个满月并排的大小。
尽管这张图像仅捕捉了面纱星云在某一时刻的状态，但它有助于研究人员了解超新星遗迹在数十年间如何演化。将这张快照与1994年哈勃的观测数据结合，可以揭示这段时间内气体结和丝状结构的运动，从而加深我们对这一壮丽星云的理解。
