Learn how to find the planets and constellations visible in the night sky during three shows presented Friday by the York County Astronomical Society.

In "Max Goes to the Moon," a dog and a girl visit the moon, with an exploration of the science necessary for the trip. In "StarWatch," visitors explore the current night sky, locate visible constellations and learn sky lore. In "Winter Wonders," two girls learn about the winter solstice as well as the cultural and religious rituals of various faiths.

"Max" starts at 7 p.m., "StarWatch" at 7:40 p.m. and "Wonders" at 8:20 p.m. The planetarium is in the York Learning Center, 300 E. Sixth Ave., North York. Admission is $4 for adults and $3 for children and seniors. Admission to any second or third show is $1 each. For more information, visit www.ycas.org.
