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.

                              2022 November 29
    [2]The featured image shows a grand skyscape with a brown desert road
     in the foreground and a sky containing the Milky Way galactic band
      complete with a large red glow on the right which is the dim Gum
   Nebula. The LMC galaxy is also visible. Please see the explanation for
                         more detailed information.

   Explanation: Because the Gum Nebula is the closest [4]supernova
   remnant, it is actually hard to see. Spanning 40 [5]degrees across the
   sky, the nebula appears so [6]large and faint that it is easily lost in
   the din of a bright and complex background. The [7]Gum Nebula is
   highlighted nicely in red emission toward the right of the featured
   wide-angle, single-image photograph taken in late May. Also visible in
   the frame are the [8]Atacama Desert in [9]Chile in the foreground, the
   [10]Carina Nebula in the plane of our [11]Milky Way galaxy running
   diagonally down from the upper left, and the neighboring [12]Large
   Magellanic Cloud (LMC) galaxy. The [13]Gum Nebula is [14]so close that
   we are much nearer the front edge than the back edge, each measuring
   450 and 1500 [15]light years respectively. The [16]complicated nebula
   lies in the direction of the [17]constellations of [18]Puppis and
   [19]Vela. Oddly, much remains unknown about the [20]Gum Nebula,
   including the timing and even number of [21]supernova explosions that
   formed it.
