每个人都能看到太阳。没人去过那里。然而，从2018年开始，美国宇航局发射了机器人帕克太阳探测器（PSP），首次调查太阳附近的区域。这段特色的延时视频显示了去年12月，在任何人造航天器最接近太阳的时候，从PSP的遮阳罩后面向侧面看的景象，在太阳热表面上方只有大约5个太阳直径。PSP的太阳探测器宽视场成像仪（WISPR）相机拍摄了这些图像超过7个小时，但它们在这里被数字压缩到大约5秒。太阳日冕，包括碰撞的日冕物质抛射（cme），在这里以前所未有的细节可见，恒星在背景中远远地经过。太阳不仅是地球的主要能源，而且其多变的太阳风也会压缩地球的大气，引发极光，影响电网，甚至会损坏轨道通信卫星。

verybody sees the Sun. Nobody's been there. Starting in 2018, though, NASA launched the robotic Parker Solar Probe (PSP) to investigate regions near to the Sun for the first time. The featured time-lapse video shows the view looking sideways from behind PSP's Sun shield in December during the closest approach of any human-made spacecraft to the Sun, looping down to only about five solar diameters above the Sun's hot surface. The PSP's Wide Field Imager for Solar Probe (WISPR) cameras took these images over seven hours, but they are digitally compressed here into about 5 seconds. The solar corona, including colliding coronal mass ejections (CMEs), is visible here in unprecedented detail, with stars passing far in the background. The Sun is not only Earth's dominant energy source, but its variable solar wind also compresses Earth's atmosphere, triggers auroras, affects power grids, and can even damage orbiting communication satellites.
