Lecture Information

A Holiday Visitor, the First Known Interstellar Comet

Just in time for the holidays, the comet 2I/Borisov has travelled for millions of years from a distant star to make its closest approach to Earth in December.  Its discovery in September of this year marks the first time that human beings have ever observed a comet from beyond our solar system, giving us clues about the nature of other star systems and our own origins. Join us for a special holiday lecture to learn about the birth of the solar system, comets, and our special interstellar visitor. The show will feature a visualization of the night sky projected on our dome, and an exciting live demonstration constructing an icy simulated comet.

SRJC Planetarium Update After Feasibility Study

September 24, 2019 -- This is an update to the status of the Santa Rosa Junior College (SRJC) planetarium.  Originally built in 1980, the planetarium closed temporarily in Fall 2018 to perform a feasibility study of the aging structure and equipment. The planetarium still remains closed for public shows but is open for instructional purposes to support the Astronomy program.

The study is now complete, which outlines a variety of options and costs that address the issues of equipment and technology that is nearly four decades old. A full renovation of the planetarium is estimated to cost approximately $2.5M to $3.5M. In addition to a one-time renovation cost, another consideration to re-opening is the ongoing staffing costs required to offer shows to the public and K-12 schools. Tied to decisions around a possible renovation is SRJC is currently addressing an ongoing budgetary deficit. Careful consideration is required before moving forward with a renovation to address multiple fiscal pressures.

Understanding these constraints, SRJC is considering a variety of creative options to provide an educational resource in astronomy and the sciences to the community. No overall decision has been made, but SRJC is exploring multiple solutions that are fiscally responsible and long-term. 

We will update the community soon with our efforts regarding the future of the planetarium space.
