Summer officially arrives at 1:49 p.m. Monday, and Hansen Planetarium is offering a free half-hour lecture about the change of seasons.
"Known as the June or summer solstice, the event marks the exact moment when the sun reaches its northernmost point in the sky," said the planetarium's Patrick Wiggins. "Beginning the next morning, the sun will start rising farther and farther south until late December."Residents of Earth's Northern Hemisphere know the June solstice as the start of the increasingly warm days of summer. But for those living on the world's southern half, it's the start of cold season.
The lecture will begin at 12:15 p.m. Monday at the planetarium, 15 S. State.
