英文原文:Explanation: NGC 1333 is seen in visible light as a reflection nebula , dominated by bluish hues characteristic of starlight reflected by interstellar dust. A mere 1,000 light-years distant toward the heroic constellation Perseus , it lies at the edge of a large, star-forming molecular cloud . This telescopic close-up spans over two full moons on the sky or just over 15 light-years at the estimated distance of NGC 1333. It shows details of the dusty region along with telltale hints of contrasty red emission from Herbig-Haro objects, jets and shocked glowing gas emanating from recently formed stars. In fact, NGC 1333 contains hundreds of stars less than a million years old, most still hidden from optical telescopes by the pervasive stardust . The chaotic environment may be similar to one in which our own Sun formed over 4.5 billion years ago. 说明: NGC 1333 在可见光下呈现为反射星云[3],其蓝色色调是星光被星际尘埃反射的特征。 这个星云距离我们仅约1,000光年,位于英勇的英仙座[4]方向,坐落于一个大型恒星形成分子云[5]的边缘。 这张望远镜近景照片[6]横跨天空中两个满月的距离,或以 NGC 1333 的估计距离计算,大约超过 15 光年。 照片展现了尘埃区域的细节,以及赫比格-哈罗[7]天体发出的对比鲜明的红色辐射,这些是从最近形成的恒星所发出的喷流和震波发光气体[8]。 事实上,NGC 1333 包含数百颗年龄不到百万年的恒星,其中大多数仍被弥漫的星尘[9]所屏蔽,无法被光学望远镜观测到[10]。 这种混乱的环境可能与我们太阳在 45 亿多年前形成时的环境类似。
