在仅仅390光年之外的蛇夫座分子云复合体中，类太阳恒星和未来的行星系统正在形成，这是离我们美丽的星球最近的恒星形成区。詹姆斯韦伯太空望远镜的NIRCam凝视着附近的混沌，以令人鼓舞的规模捕捉到这张红外图像。这张壮观的宇宙快照是为了庆祝韦伯太空望远镜成功探索宇宙的第一年而发布的。这个框架横跨蛇夫座区域不到一光年，包含了大约50颗年轻的恒星。较亮的恒星明显具有韦伯衍射峰的特征模式。从新生恒星中喷出的巨大的受冲击的氢分子射流在图像中是红色的，在其中心附近有一个巨大的黄色尘埃空洞，是由精力充沛的年轻恒星雕刻出来的。在这张令人惊叹的图片中，一些恒星附近是原行星盘投下的阴影。

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 spectacular cosmic snapshot was released to celebrate the successful first year of Webb's exploration of the Universe. The frame spans less than a light-year across the Rho Ophiuchi region and contains about 50 young stars. Brighter stars clearly sport 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.
