   Explanation: The Sun is hidden by a horizon that runs across the middle
   in this two hemisphere view of [7]Earth's night sky. The digitally
   stitched mosaics were recorded from corresponding latitudes, one 29
   degrees north and one 29 degrees south of the planet's equator. On top
   is the northern view from the [8]IAC observatory at La Palma taken in
   February 2020. Below is a well-matched southern scene from the [9]ESO
   La Silla Observatory recorded in April 2016. In this projection, the
   Milky Way runs almost vertically above and below the horizon. Its dark
   clouds and and bright nebulae are prominent near the galactic center in
   the lower half of the frame. In the upper half, brilliant Venus is
   immersed in zodiacal light. Sunlight faintly scattered by
   interplanetary dust, the zodiacal light traces the [10]Solar System's
   ecliptic plane in a complete circle through the starry sky. Large
   telescope domes bulge along the inverted horizon from La Silla while at
   La Palma, multi-mirror Magic telescopes stand above center. [11]Explore
   this two hemisphere night sky and you can also find the Andromeda
   Galaxy and the Large and Small Magellanic Clouds.
