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.

                               2024 November 6
   [2]A town is shown in the foreground surrounded by tall mountains with
   even taller mountains in the distance. Above them all is a bright white
    streak that is a comet with both a tail and an anti-tail. High above
       are stars in the night sky. Please see the explanation for more
                            detailed information.

   Explanation: Comet Tsuchinshan-Atlas is now headed back to the outer
   [4]Solar System. The massive dusty snowball put on [5]quite a show
   during its trip near the Sun, resulting in many impressive pictures
   from [6]planet Earth during October. The [7]featured image was taken in
   mid-October and shows a defining visual feature of the comet -- its
   impressive [8]anti-tail. The image captures Comet [9]C/2023 A3
   (Tsuchinshan–ATLAS) with [10]impressively long [11]dust and [12]ion
   tails pointing up and away from the Sun, while the [13]strong anti-tail
   -- composed of more massive dust particles -- trails the comet and
   points down and (nearly) toward the recently-set [14]Sun. In the
   foreground is village of [15]Tai di Cadore, [16]Italy, with the
   tremendous [17]Dolomite Mountains in the background. Another comet,
   [18]C/2024 S1 (ATLAS), once a candidate to rival Comet
   Tsuchinshan-Atlas in brightness, [19]broke up last week during its
   close approach to our Sun.
