任务简介

詹姆斯·韦伯太空望远镜是由NASA、ESA和CSA开发的太空望远镜，旨在接替哈勃太空望远镜成为NASA旗舰级天体物理任务。其主镜（光学望远镜元件）由18块六边形镜片组成，组合后形成直径6.5米的镜面，远大于哈勃的2.4米镜面。这将使JWST在红外分辨率和灵敏度上超越哈勃，并支持天文学和宇宙学领域的广泛研究，包括观测宇宙中最遥远的事件和天体，如首批星系的形成。

↗ James Webb Space Telescope

The James Webb Space Telescope is a space telescope developed by NASA, ESA and CSA to succeed the Hubble Space Telescope as NASA's flagship astrophysics mission. Its primary mirror, the Optical Telescope Element, is composed of 18 hexagonal mirror segments which combine to create a 6.5 m diameter mirror, considerably larger than Hubble's 2.4 m mirror. This will allow JWST to provide improved infrared resolution and sensitivity over Hubble, and will enable a broad range of investigations across the fields of astronomy and cosmology, including observing some of the most distant events and objects in the universe, such as the formation of the first galaxies.
