KELSEYVILLE, Calif. – Join the Taylor Observatory-Norton Planetarium on Saturday, Feb. 16, for “What if the moon didn't exist?”

The presentation will take place from 8 p.m. to 11 p.m. at the observatory, 5725 Oak Hills Lane, Kelseyville.

It’s now thought that the moon was created when another planet collided with the Earth. How would life be different if this event hadn’t happened?

A day would be only about eight hours long and gale force winds of 200 mile per hour would be common.

Join them as guest speaker, Stephen Pollaine, explains various things, like how tidal forces work and how all of this affects our calendar in surprising ways.

Dr. Pollaine has a Ph.D. in astrophysics from U.C. Berkeley and a bachelor's degree from Yale. He worked for more than 30 years at the Lawrence Livermore National Laboratory in fusion energy research. He is now retired and living in Loch Lomond.

Lake County's Window to the Universe is held on the third Saturday of each month. The evening's event includes a science topic presentation, a planetarium experience and astronomical viewing. Public events are held regardless of weather. Please dress accordingly.

Suggested donation is $5 per adult and $3 per child under 12 years.
