The California Academy of Sciences and the Contemporary Jewish Museum, two jewels in San Francisco’s crown, have set reopening plans for October with new COVID-19 precautions in place.

The Academy will reopen to members and donors on Tuesday. The general public is invited starting Friday, Oct. 23. The number of guests will be limited, timed reservations as well as masks and social distancing will be required.

The Academy will offer new exhibits including “BigPicture,” a nature photography display from around the world with 49 unforgettable images from its annual competition. A brand-new aquarium exhibit, “Venom: Fangs, Stingers, and Spines,” will explore how often-feared but biologically important species use venom to capture prey and defend against predators.

A new exhibit at the Morrison Planetarium is planned, but the planetarium will remain closed for now. Visitors, however, can view “Big Astronomy” online from home. The planetarium show, which explores Chile’s mountaintop observatories and the people that keep them running, airs at 11:30 a.m. every Wednesday on YouTube.

The Contemporary Jewish Museum, which has been closed since March 13, reopens to the general public on Saturday, Oct. 17. Members can get early access, Thursday and Friday, Oct. 15-16.

The museum has extended the showing of exhibits that were on display when the pandemic forced the closure, as well as some new ones.

“Levi Strauss: A History of American Style” and “Threads of Jewish Life: Ritual and Other Textiles from the San Francisco Bay Area,” have both been extended through early 2021. The Museum also will debut “Predicting the Past: Zohar Studios, The Lost Years,” which will also be on view through early 2021.

Advance, timed reservations also will be required, as will masks and other guidelines.

Admissions will be limited to allow for social distancing. To reduce high-capacity gatherings and person-to-person contact, the Museum will continue to host programming online only, including the popular visual lecture series, Sunday Stories, on Facebook and IGTV; Art for Lunch programs that take place periodically on Fridays; and exclusive virtual programs for members and donors.

The Museum’s education department will continue offering live virtual tours for school groups, which served more than 1,700 teachers and students last spring. Those who prefer to remain at home will still be able to explore virtual exhibitions.
