詹姆斯·韦伯太空望远镜拍摄的这组壮观的马赛克图像窥视了年轻星团ngc1333的中心。距离英仙座只有1000光年的距离，附近的星团位于巨大英仙座分子云的边缘。作为韦伯对该区域进行深入探索以识别低质量褐矮星和自由漂浮行星的一部分，该太空望远镜的综合视野跨越了尘埃星团湍流恒星托儿所近2光年。事实上，NGC 1333已知拥有年龄不到100万年的恒星，尽管大多数恒星被无处不在的星尘所掩盖，无法通过光学望远镜观测到。这种混乱的环境可能类似于45亿年前我们的太阳形成时的环境。

This spectacular mosaic of images from the James Webb Space Telescope peers into the heart of young star cluster NGC 1333. A mere 1,000 light-years distant toward the heroic constellation Perseus, the nearby star cluster lies at the edge of the large Perseus molecular cloud. Part of Webb's deep exploration of the region to identify low mass brown dwarf stars and free floating planets, the space telescope's combined field of view spans nearly 2 light-years across the dusty cluster's turbulent stellar nursery. In fact, NGC 1333 is known to harbor stars less than a million years old, though most are 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.
