             Animation: Comet Tsuchinshan-ATLAS Tails Prediction

   Explanation: How bright and strange will the tails of Comet
   Tsuchinshan-ATLAS become? [4]The comet has brightened dramatically over
   the few weeks as it passed its closest to [5]the Sun and, just three
   days ago, passed its closest to the Earth. [6]C/2023 A3
   (Tsuchinshan–ATLAS) became of the [7]brightest comets of the past
   century over the past few days, but was unfortunately hard to see
   because it was so nearly superposed on the Sun. As [8]the comet appears
   to move away from the Sun, it is becoming a [9]remarkable sight -- but
   may soon begin to fade. The [10]featured animated video shows how the
   comet's tails have developed, as viewed from Earth, and gives one
   prediction about how they might further develop. As shown in the video,
   heavier parts of the [11]dust tail that trails the comet have begun to
   appear to point in [12]nearly the opposite direction from lighter parts
   of the dust tail as well as the comet's [13]ion tail, the blue tail
   that is pushed directly out from the Sun by the [14]solar wind.
