The naked eye is just fine – but if the night sky is clear this evening, the best way to view the moon is with a pair of binoculars, revealing craters, seas, bays and more. In addition, Saturn and Mars are still hanging in the early evening sky. The constellations Pegasus, Andromeda, Cassiopeia and Perseus are rising in the east.
Tomorrow marks the 95th year since attendees took in the first planetarium show, at the Deutches Museum in Munich, Germany. Actually, indoor depictions of the night sky go back to 1,500 B.C. in Egyptian tombs. The Adler Planetarium in Chicago was first in the United States in 1930. The Fels Planetarium at the Franklin Institute in Philadelphia opened four years later, as the second planetarium in the US.
