真正的Roman

刚刚离开地球的 Roman 空间望远镜，究竟是一台怎样的望远镜？ 有人说，它是韦布空间望远镜的接任者；也有人说，它比哈勃强大100倍。 但真正的 Roman，并不是一台单纯“更强”的太空望远镜。 它拥有和哈勃几乎相同的2.4米主镜，却拥有巨大的宽视场相机，可以在接近哈勃分辨率的同时，一次拍下大得多的天空。 这期视频，我们从它的光学系统、巨大焦平面和巡天能力出发，看看 Roman 为什么如此特别。 它将如何研究暗能量、寻找系外行星，并改变未来天文学家观察宇宙的方式？ 这才是真正的 Roman。 #Roman #RomanSpaceTelescope #NancyGraceRoman #罗曼空间望远镜 #南希格蕾丝罗曼空间望远镜 #NASA #太空望远镜 #哈勃望远镜 #Hubble #韦布望远镜 #JamesWebb #JWST #欧几里得望远镜 #Euclid #天文学 #宇宙 #太空 #深空 #深空摄影 #宇宙探索 #暗能量 #暗物质 #系外行星 #引力微透镜 #日冕仪 #银河系 #星系 #超新星 #天文科普 #科学科普 #航天 #Space #Astronomy #Telescope #Astrophysics #Cosmology #Exoplanet #DarkEnergy #DarkMatter #Galaxy #Universe #spacescience Media Sources, Credits, and Copyright Notice This video uses imagery, engineering footage, animations, and scientific visualizations related to the Hubble Space Telescope, the James Webb Space Telescope, and the Nancy Grace Roman Space Telescope.
