说明: 距离地球仅390光年的蛇夫座心宿增四星云复合体中正在形成类似太阳的恒星和未来的行星系统，詹姆斯·韦伯太空望远镜的近红外相机深入观测了这个距离我们美丽星球最近的恒星形成区，以红外线影像捕捉到了令人振奋的规模。这幅画面影像横跨蛇夫座心宿增四区域不到一光年，包含大约50颗年轻恒星。较亮的恒星清晰地展示了韦伯望远镜特有的绕射尖峰图案。新生恒星喷发出巨大的分子氢喷流从，在影像中呈现红色，并由位于中心附近的年轻恒星雕刻出巨大而泛黄的尘埃空腔。在这幅惊叹的影像中，一些恒星附近的阴影是由其原行星盘投射的。这幅壮观的宇宙快照于2023年发布，以庆祝韦伯望远镜宇宙探索成功的第一年。

英文原文:
Explanation: A mere 390 light-years away , Sun-like stars and future planetary systems are forming in the Rho Ophiuchi molecular cloud complex, the closest star-forming region to our fair planet. The James Webb Space Telescope’s NIRCam peered into the nearby natal chaos to capture this infrared image at an inspiring scale . The frame spans less than a light-year across the Rho Ophiuchi region and contains about 50 young stars. Brighter stars clearly show Webb’s characteristic pattern of diffraction spikes . Huge jets of shocked molecular hydrogen blasting from newborn stars are red in the image, with the large, yellowish dusty cavity carved out by the energetic young star near its center. Near some stars in the stunning image are shadows cast by their protoplanetary disks . The spectacular cosmic snapshot was released in 2023 to celebrate the successful first year of Webb’s exploration of the Universe.
