詹姆斯·韦伯太空望远镜观察到一个球状星团，星团中有不同的恒星在闪烁
詹姆斯·韦伯太空望远镜的NIRCam仪器拍摄到的球状星团M92的图像。该图像由四种不同滤镜的四次曝光合成而成：F090W（波长0.9微米）以蓝色显示；F150W（波长1.5微米）以青色显示；F277W（波长2.77微米）以黄色显示；F444W（波长4.44微米）以红色显示。中心的黑色条纹是芯片间隙，这是NIRCam的两个长波长检测器分离的结果。这个空隙覆盖了星团密集的中心，它太亮了，无法同时拍摄到星团较暗、较不致密的外围。这张图像的直径约为5弧分（39光年）。从太空望远镜科学研究所的资源库下载M92的全分辨率图像。 影像来源：NASA, ESA, CSA, A. Pagan (STScI). 编者按：本文重点介绍了韦伯科学进展中的数据，这些数据尚未通过同行评审。 2022年6月20日，詹姆斯·韦伯太空望远镜花了...
