Today:
Should you look due south at 6 o’clock this evening, once the last of the twilight has been vanquished, Saturn reaches it highest point, close to half way from the horizon to the zenith. Directly above Saturn appears a large square of modestly brighter stars, forming the Great Square of Pegasus. The square forms his chest and shoulders, yet he’s upside down, with his neck and head extending to the right, from the lower right corner.
