The Griffith Observatory will hold an installment of its All Space Considered free public lecture series on Friday, Jan. 17, at 7:30 p.m. in the Leonard Nimoy Event Horizon theater.

The program offers a look at some of the most talked about subjects in astronomy, science and space exploration, and programs are conducted on the first Friday of each month.

The January program celebrates the end of the Spitzer Space Telescope mission with special guests, NASA/JPL and Spitzer scientists Michael Werner and Peter Eisenhardt, who will discuss their new book “More Things in the Heavens: How Infrared Astronomy is Expanding Our View of the Universe.” A book-signing will follow the program.

Additional topics include “what is in store for the fading star Betelguese?,” “water ice on Mars,” “the latest developments in commercial crew launch vehicles,” “headlines from the 235th meeting of the American Astronomical Society,” “pretty pictures” and “the January sky report.”

People planning to attend are encouraged to ride the DASH Observatory bus from the Vermont/Sunset Metro Red Line station or from free parking at the Greek Theatre. The Observatory is located at 2800 E. Observatory Road. For information, call (213)473-0800, or visit griffithobservatory.org.
