The Night Sky in Pennsylvania
A year of the night sky from Pennsylvania — planets, moon phases, and meteor showers.
The night sky changes with the seasons more than with the state line, but your latitude sets how high each constellation climbs and which southern stars clear the horizon. In Pennsylvania, winter brings Orion and the bright stars of the Winter Hexagon; spring turns to Leo and the realm of galaxies; summer raises the Milky Way core and the Summer Triangle; and autumn opens to Pegasus and the Andromeda Galaxy.
The printable Pennsylvania night-sky guide lists this year's exact planet visibility, moon phases, and meteor-shower peaks from your latitude.
