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 October 7
        [2]A starry sky is pictured with a long bright streak running
   diagonally from the lower left to the upper right. The lower left part
   of the sky sky orange sprinkled with a few dark clouds. Please see the
                 explanation for more detailed information.

   Explanation: A bright comet is moving into the evening skies. [4]C/2023
   A3 (Tsuchinshan–ATLAS) has brightened and even though it is now easily
   [5]visible to the unaided eye, it is so near to the Sun that it is
   still difficult to see. [6]Pictured, Comet [7]Tsuchinshan–ATLAS was
   captured just before sunrise from an [8]Andes Mountain in [9]Peru.
   Braving cold weather, this unusually [10]high perch gave the
   astrophotographer such a low eastern horizon that the [11]comet was
   obvious in the pre-dawn sky. Visible in the [12]featured image is not
   only an [13]impressively long dust tail extending over [14]many
   degrees, but an impressively long and blue [15]ion tail, too.  This
   month, as the [16]comet moves out from the [17]Sun and passes the
   [18]Earth, evening observers should be able to see the huge dirty
   [19]ice ball toward the west just after [20]sunset.
