在玫瑰星云的中心,有一群明亮的恒星照亮了整个星云。NGC 2244的恒星是在几百万年前由周围的气体形成的。这张特色照片拍摄于1月中旬,使用多次曝光和非常特定的颜色硫(阴影红色),氢(绿色)和氧(蓝色),以惊人的细节捕捉了中心区域。一股热风的粒子流从星团的恒星中流出,在缓慢疏散星团中心的同时,使已经很复杂的气体和尘埃细丝更加复杂。玫瑰星云的中心直径约50光年,距离约5200光年,用双筒望远镜可以看到独角兽星座(麒麟座)。你的天空惊喜:APOD在你的生日上展示了什么照片?(1995后)

In the heart of the Rosette Nebula lies a bright cluster of stars that lights up the nebula. The stars of NGC 2244 formed from the surrounding gas only a few million years ago. The featured image taken in mid-January using multiple exposures and very specific colors of Sulfur (shaded red), Hydrogen (green), and Oxygen (blue), captures the central region in tremendous detail. A hot wind of particles streams away from the cluster stars and contributes to an already complex menagerie of gas and dust filaments while slowly evacuating the cluster center. The Rosette Nebula's center measures about 50 light-years across, lies about 5,200 light-years away, and is visible with binoculars towards the constellation of the Unicorn (Monoceros).
