Three days earlier NASA's Solar Dynamics Observatory(SDO), a sun-monitoring satellite, witnessed a magnetic eruption on the sun, which unleashed a gigantic cloud of charged particles into space. 就在三日前,美国宇航局(NASA)的太阳动态观察站(一个太阳监测活动卫星)监测到了太阳表面发生了磁喷发。这场磁喷发向太空释放了大量的带电粒子。
Researchers have showed off brightly coloured images and short movie clips of the sun from the Solar Dynamics Observatory(SDO) in a webcast. 太阳动力学观测台的科学家们在网上展示了一组鲜艳的太阳风暴图片和视频短片。
The pictures were taken by the Solar Dynamics Observatory(SDO) ( SDO ), which is the most advanced spacecraft ever designed to study the Sun. 这些照片都是在太阳动力学观测站上拍摄到的,它目前是研究太阳这个天体中,最先进的航天器。
