   Explanation: Does the Sun return to the same spot on the sky every day?
   No. A better and more visual answer to that question is an analemma, a
   composite of images taken at the same time and from the same place over
   the course of a year. The featured analemma was compiled at 4:30 pm
   many afternoons from Taiwan during 2021, with the city skyline of
   Taipei in the foreground, including tall Taipei 101. The Sun's location
   in December -- at the December solstice -- is shown on the far left,
   while its location at the June solstice is captured on the far right.
   Also shown are the positions of the Sun throughout the rest of the day
   on the solstices and equinoxes. Today is the June solstice of 2022, the
   day in Earth's northern hemisphere when the Sun spends the longest time
   in the sky. In many countries, today marks the official beginning of a
   new season, for example winter in Earth's southern hemisphere.
