太空中有一个新的大望远镜。詹姆斯·韦伯太空望远镜（JWST）不仅拥有比哈勃望远镜大五倍的镜面，而且在红外光下也能看得更清楚。这张特色图片显示了昨天从法属圭亚那发射的阿丽亚娜5号火箭的上一级释放后，JWST在地球上空的高度。在接下来的一个月里，JWST将移动到太阳-地球L2点附近，在那里它将与地球共同绕太阳运行。在这段时间和接下来的五个月里，JWST将解开它的分割镜和一系列复杂的科学仪器，并对它们进行测试。如果一切顺利，JWST将于2022年夏天开始研究宇宙中的星系和银河系中围绕恒星运行的行星。APOD画廊：韦伯太空望远镜发射

There's a big new telescope in space. This one, the James Webb Space Telescope (JWST), not only has a mirror over five times larger than Hubble's in area, but can see better in infrared light. The featured picture shows JWST high above the Earth just after being released by the upper stage of an Ariane V rocket, launched yesterday from French Guiana. Over the next month, JWST will move out near the Sun-Earth L2 point where it will co-orbit the Sun with the Earth. During this time and for the next five months, JWST will unravel its segmented mirror and an array of sophisticated scientific instruments -- and test them. If all goes well, JWST will start examining galaxies across the universe and planets orbiting stars across our Milky Way Galaxy in the summer of 2022. APOD Gallery: Webb Space Telescope Launch
