Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

   Explanation: What's happening near the Sun? To help find out, NASA
   [11]launch[12]ed the robotic [13]Parker Solar Probe (PSP) to
   [14]investigate regions closer to the Sun than ever before. The
   [15]PSP's looping [16]orbit brings it nearer to the Sun [17]each time
   around -- every few months. The [18]featured time-lapse video shows the
   view looking sideways from [19]behind PSP's Sun shield during its 16th
   approach to the Sun last year -- from well within the orbit of
   [20]Mercury. The [21]PSP's Wide Field Imager for Solar Probe
   ([22]WISPR) cameras took the images over eleven days, but they are
   digitally compressed here into about one minute video. The waving of
   the [23]solar corona is visible, as is a [24]coronal mass ejection,
   with stars, planets, and even the central band of our [25]Milky Way
   Galaxy streaming by in the background as the PSP orbits the Sun.
   [26]PSP has found the solar neighborhood to be [27]surprisingly complex
   and to include [28]switchbacks -- times when the [29]Sun's magnetic
   field briefly reverses itself.
