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.

                              2021 December 15
      [2]The picture shows a Comet Leonard from space. Also visible are
   auroras, a meteor, the Earth's atmosphere, stars, and satellite trails.
   The image was taken by Origin.Space's Yangwang-1 telescope. Please see
               the explanation for more detailed information.

   Explanation: What does Comet Leonard look like from space? Today's
   [5]featured image from [6]Origin.Space's [7]Yangwang-1 [8]space
   telescope shows not only the [9]currently bright comet -- but several
   other [10]space delights as well. Taken in optical and [11]ultraviolet
   light, [12]C/2021 A1 (Leonard) is visible with an [13]extended tail
   near the image center as it appeared five days ago. The Earth is
   visible on the lower right, while layers of the [14]Earth's atmosphere
   glow diagonally from the lower left to the upper right. The [15]trails
   of two satellites can be seen in front of a myriad of distant stars
   that dot the background on the upper left. The faint bands of light
   running diagonally from the lower right to the upper left are
   [16]auroras. Finally, the image also caught a [17]meteor streaking just
   below the [18]airglow. To [19]see Comet Leonard yourself from the
   Earth's surface during the next few days, look toward the western
   horizon just after sunset or just before sunrise.
