NGC 1333: Stellar Nursery in Perseus
Image Credit & Copyright: Robert Eder
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.

NGC 1333: 英仙座的恒星摇篮

说明: NGC 1333在可见光下呈现为反射星云，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，位于英勇的英仙座方向，坐落于一个大型恒星形成分子云的边缘。这张望远镜近景照片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。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所遮蔽，无法被光学望远镜观测到。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。
