      Explanation: What's happening near the Sun? To help find out, NASA   
      launched the robotic Parker Solar Probe (PSP) to investigate regions   
      closer to the Sun than ever before. The PSP's looping orbit brings it   
      nearer to the Sun each time around -- every few months. The featured   
      time-lapse video shows the view looking sideways from behind PSP's Sun   
      shield during its 16th approach to the Sun last year -- from well   
      within the orbit of Mercury. The PSP's Wide Field Imager for Solar   
      Probe (WISPR) cameras took the images over eleven days, but they are   
      digitally compressed here into about one minute video. The waving of   
      the solar corona is visible, as is a coronal mass ejection, with stars,   
      planets, and even the central band of our Milky Way Galaxy streaming by   
      in the background as the PSP orbits the Sun. PSP has found the solar   
      neighborhood to be surprisingly complex and to include switchbacks --   
      times when the Sun's magnetic field briefly reverses itself.
