Astronomers make a living unlocking the mysteries of the cosmos. Learn a little bit about what they know at the Spring Night Sky lecture series at Taylor Observatory in Kelseyville. Each evening will begin with one hour in the planetarium, where participants will listen to astronomical mythology and discover how to locate seasonal constellations. Then, at the lecture, detailed information will be given about specific star groups. Talks are open to high schoolers and adults, and will be held 8–10 p.m. on March 18 and 25 and April 15 and 22. Admission is $15 for each lecture. Find a complete schedule at facebook.com/friendsoftaylorobservatory.
