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.

     [2]The Sun's path is shown while setting in multiple exposures over
    three separate days. The top path was taken during a summer solstice,
    the middle path during an equinox, and the lower path during a winter
    solstice. The foreground shows grass and some rocks and trees. Please
             see the explanation for more detailed information.

   Explanation: Does the Sun follow the same path every day? [4]No. The
   Sun's path changes during the year, tracing a longer route during the
   summer than the winter. [5]Pictured here, the [6]Sun's arc was captured
   from noon to sunset on three days, from highest in the sky to lowest:
   [7]summer solstice, [8]equinox, and [9]winter solstice. The images were
   taken near [10]Gatto Corvino Village in [11]Sicily, [12]Italy in 2020
   and 2021. The path and time the [13]Sun spends in the sky is more
   important in [14]determining the season than how close the Earth is to
   the [15]Sun. In fact, the [16]Earth is closest to the Sun in January,
   during northern winter. Today is a [17]solstice, so [18]today the Sun
   is taking its longest path of the year across the sky in Earth's
   [19]northern hemisphere, but the shortest path in the [20]southern
   hemisphere.
