一架新的望远镜已被发射到太空以研究宇宙。南希·格蕾丝·罗马太空望远镜（RST）的主镜大小与哈勃太空望远镜（HST）相同，但每次拍摄时看到的天空是哈勃望远镜的100倍。这是可能的，因为与HST相比，RST的主镜更弯曲，副镜更近，主相机更大。结果是，RST可以更快地检查更多的天空，除了其他功能之外，可能还会发现更多的超新星，这些超新星会告诉我们更多关于宇宙膨胀率和组成的信息，以及更多围绕其他恒星运行的行星，这些行星会告诉我们更多关于宇宙中其他地方存在生命的可能性。RST将围绕太阳运行，而不是像詹姆斯·韦伯太空望远镜那样围绕地球运行。这段视频显示，罗曼昨天在美国佛罗里达州肯尼迪航天中心乘坐SpaceX重型猎鹰火箭升空。APOD的主要NASA网站正在迁移：从APOD .

查看原文解释
A new telescope has been launched into space to study the universe. The Nancy Grace Roman Space Telescope (RST) has the same size main mirror as the Hubble Space Telescope (HST) but sees 100 times more sky during each snapshot. This is possible because when compared to HST, RST's main mirror is more curved, its secondary mirror is closer, and its main camera is larger. The result is that RST can inspect more of the sky more quickly, likely allowing, among other capabilities, the discovery of many more supernovas which tell us more about the expansion rate and composition of our universe, and many more planets orbiting other stars that tell us more about the possibilities for life elsewhere in the universe. RST will orbit the Sun, not the Earth, like the James Webb Space Telescope. The featured video shows Roman being launched yesterday from Kennedy Space Center, Florida, USA aboard a SpaceX Falcon Heavy rocket.
