Residents can drop by the Campbell Library on Saturday to get information about a rare event in the sky that will engage people across the country.

NASA scientist Elizabeth Keller will talk about the solar eclipse set to occur on Aug. 21 and its scientific significance. The event will be from 3 to 4:30 p.m. in the community room, located in the lower level of the library, 77 Harrison Ave.

“It’s literally a once-in-a-lifetime event,” Keller says of the eclipse, adding the last solar one of this magnitude was in 1918. “This happens about every 100 years.”

Keller’s presentation is part of a Santa Clara County Library District series featuring scientists speaking about the eclipse. Keller will present a map of the eclipse’s visibility across the U.S. and discuss how to safely view it.

The eclipse will be seen first in Lincoln City, Oregon, at roughly 10:16 a.m. Pacific Standard Time and end in Charleston, South Carolina, at 2:48 p.m. East Coast Standard Time.

While Californians will not be able to see the total eclipse from their home state, Keller says, they’ll have partial visibility.

“NASA plans to live stream the eclipse,” Keller says, adding she will direct people to the proper website to see when it’s happening.

Safety glasses to be used on the day of the eclipse will be handed out while supplies last, according to Lili Smith, the library district’s public communication specialist.

Keller will also share information about some of the experiments NASA will be doing during the eclipse. She says the eclipse is an example of “citizen science,” where the public can actively participate in a scientific event.

“It’s very exciting to see how NASA is capitalizing on this once-in-a-lifetime event,” Keller says.

Keller hopes she can dispel eclipse myths that commonly come up and answer any questions thrown her way.

“I hope this inspires the next generation,” she says.

The event at the library will also feature crafts and story times with a focus on solar and science themes throughout the day. Videos from NASA about space exploration will also be played.

Similar events will be Aug. 12 at the Milpitas Library, Aug. 13 at the Saratoga Library and Aug. 19 at the Morgan Hill Library. The Milpitas Library will host Andrew Fraknoi, the chair of the astronomy department at Foothill College and co-author of “When the Sun Goes Dark.”
