Welcome to the
Peninsula Astronomical Society

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 generally holds its meetings on the second Friday of each month at 7:30 pm, either on the campus of Foothill College (between San Jose and Palo Alto) in Los Altos Hills, or at the Los Altos Public Library. 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 at Foothill College – 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.

“Touring Exotic Landforms Across the Solar System:
Adventures in Planetary Geomorphology”

with NASA/Ames SSERVI scientist BRIAN DAY

February 14th, (yes, Valentine’s Day) 2020 at 7:30pm
Foothill College, Room 5015
12345 El Monte Road, Los Altos Hills, CA

Brian is an expert at Public Outreach featuring NASA web-portals of the Moon, Mercury, Mars, Ceres, Vesta and many other bodies in the Solar System.  He will explore with us the most interesting features he has come across in his studies.

Brian Day is the Lead for Citizen Science and Community Development at the Solar System Exploration Research Virtual Institute (SSERVI). In this role, he coordinates programs with numerous internal and external partnering organizations, focusing on providing opportunities for students and the public to directly participate in NASA science and exploration.

He currently acts as SSERVI’s project manager for NASA’s Lunar Mapping and Modeling Portal (http://lmmp.nasa.gov), a set of tools designed for mission planning, lunar science, and public outreach. From 2010-2014, Brian served as the Education/Public Outreach Lead for NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) mission to the Moon, which flew through and studied the Moon’s tenuous atmosphere. From 2007-2010 he served as the E/PO Lead for NASA’s LCROSS lunar impactor mission which discovered deposits of water ice at the Moon’s South Pole. He has also participated in producing the Education/Public Outreach sections for numerous NASA mission proposals. Brian has played key roles in various NASA Mars Analog Field Studies, providing technical support in the field for webcasts and robotic rover tests in extreme environments here on Earth. In 2007, he flew on the Aurigid-MAC mission to record fragments of comet Kiess entering Earth’s upper atmosphere.
