镜面校准:韦伯望远镜的第一张全彩图像将于7月发布

After completing two additional mirror alignment steps in March 2022, the team confirmed the James Webb Space Telescope’s optical performance will be able to meet or exceed the science goals the observatory was built to achieve.

This “selfie” was created using a specialized pupil imaging lens inside of Webb’s Near Infrared Camera, or NIRCam, instrument, which was designed to take images of the primary mirror segments instead of images of the sky. This configuration is not used during scientific operations and is used strictly for engineering and alignment purposes. In this image, all of Webb’s 18 primary mirror segments are shown collecting light from the same star in unison.

Now, we’re counting down to the release of the Webb Telescope’s first full-color images and spectroscopic data during a broadcast beginning at 10:30 a.m. EDT on Tuesday, July 12.

2022年3月,在完成两个额外的镜面校准步骤后,该团队确认詹姆斯·韦伯太空望远镜的光学性能将能够达到或超过该天文台的科学目标。

这张“自拍”是使用韦伯的近红外相机(NIRCam)内的一个专门的瞳孔成像镜头制作,该仪器旨在拍摄主镜段的图像,而不是天空图像。此配置在科学操作期间不使用,仅用于工程和校准目的。在这张图片中,韦伯的所有18个主镜段都一致地收集来自同一颗恒星的光。

现在,我们正在倒计时,7月12日,星期二,美国东部夏令时上午10:30开始广播,届时将发布韦伯望远镜的第一张全彩图像和光谱数据。
