 Welcome to the
Peninsula Astronomical Society's
web site.


The Peninsula Astronomical Society is a group of some 200 Bay Area astronomy enthusiasts of all ages and backgrounds. Some members are professionally trained in astronomy, others are just starting and have never looked through a telescope before. One thing that we all have in common is an interest in the sky.

The PAS holds meetings on the second Friday of each month at 7:30 pm on the campus of Foothill College in Los Altos Hills, CA (between San Jose and Palo Alto).  The meetings are usually held in Room 5015, next to Parking Lot 5 (see map). Each meeting features a speaker (or speakers) bringing us up to date on different topics in astronomy. The public is welcome to attend these meetings; there is no charge to attend.  Note, however, that there is a $3 charge for parking - visitor parking permits are available from the machines in the parking lots.  Please do not park in spaces marked "Staff" - you will be ticketed!

As part of its commitment to bringing astronomy to the public, the Peninsula Astronomical Society operates the Foothill College Observatory (click here for more information). The Observatory is staffed by members of the society who volunteer to conduct the regularly scheduled public programs.

In addition to operating the Foothill Observatory, the PAS has its own observatory in the nearby Santa Cruz Mountains. This location has AC power and room for members to set up their own telescopes at our monthly star parties. This site is also the home of the society's 12" telescope, available for member use after a checkout.

"Can Red Dwarf Stars

Host Habitable Planets?"


by Dr. Gibor Basri - Professor at UC Berkeley.

Friday April 12th, 2019 at 7:30pm

  NEW VENUE - Los Altos Public Library

ADDRESS is  --  13 S. San Antonio Road, Los Altos, CA 94022

The driveway is just one block south of the San Antonio - Main Street intersection.

ABSTRACT --  Much recent news about exoplanets has concerned the discovery of earth-sized planets in the “habitable zone” of "red dwarf" stars. This is partly because such planets are more easily found around small stars, and partly because most stars are red dwarfs. Can planets in the habitable zone (I’ll expand on this concept) around a red dwarf actually harbor earth-like life? Among the potential problems are stellar magnetic activity and the fact that the planets will always have one side towards the star. Until recently most astronomers would have said “no” but this is changing. I’ll explain why and talk about recent discoveries.


BIO -- Gibor Basri joined the faculty of the Berkeley Astronomy Department in 1982. His areas of research include star formation, solar and low mass stars, and stellar magnetic activity. He was an early pioneer in the study of brown dwarfs. He has extensively used telescopes at the Lick and Keck Observatories, and was a Co-Investigator on NASA's  Kepler mission, which has revolutionized our knowledge about exoplanets. He is a recipient of the Sagan award for communicating science.


Weather permitting, the OBSERVATORY at Foothill College will be open for public viewing

from 9 to 11pm,  just as it is every CLEAR Friday night throughout the year.
