Cosmic Explorer - a next-gen gravitational-wave observatory

With almost 100 gravitational-wave sources detected to-date, and the first-generation facilities now over 20-years old, there is growing momentum towards the next-generation of gravitational-wave observatories. Projects are underway in Europe, Australia, Japan, India and the US to bring new ground-based observatories online. These audio-band observatories will be complemented by a wide range of efforts targeting other gravitational-wave frequency-bands. In this talk, I will focus on the US effort to build a next-generation observatory, known as Cosmic Explorer.

Speakers: Matthew Evans, Massachusets Institute of Technology

The James Webb Space Telescope: Our Giant Eye on the Invisible Sky

The early images from the James Webb Space Telescope have been applauded by scientists, the media, and the public.  But there is far more to our expectations from this remarkable space instrument than just pretty pictures.  In this introductory talk, astronomer and educator Andrew Fraknoi explains what makes the Webb a truly pioneering instrument, what the early images actually show, and what scientists expect the telescope to accomplish in years to come.  In the process, he discusses how the Webb observes an “invisible universe” of infrared rays, and what astronomers are hoping to learn from it about “cosmic evolution” -- the birth and death of stars, planets, and galaxies.  No background in science is required to understand this program.

Speaker: Andrew Fraknoi teaches astronomy and physics at the Fromm Institute at the University of San Francisco and the Osher Lifelong Learning Institute at SF State University.  He is the lead author of the most frequently used introductory astronomy textbook in the country, Astronomy, published online by the nonprofit OpenStax project; Gerald Harris, Commonwealth Club, Moderator

Our Lonely Sun: How Multiple Star Systems Form (or don’t)

Most stars are born with one or more stellar companions. Observational advances over the last decade have enabled high-resolution, interferometric studies of forming multiple systems and statistical surveys of multiplicity in star-forming regions. These have yielded new insights into how such systems form and how multiplicity affects disk evolution and planetary architectures. In this talk, I will review recent observational discoveries of the youngest multiple systems. I will present the results of star cluster simulations modeling the formation and evolution of multiple systems, and I will discuss the role of dynamics and environment in setting stellar multiplicity.  Finally, I will highlight remaining numerical and observational challenges.

First Friday - Moving to Mars

This year, in early December, it will be the best time to view Mars and it is a great time to look forward to NASA’s Mission to Mars. Join NASA and SETI scientist Pascal Lee as they explore the beauty of the Martian landscape and discuss how art has influenced modern spacecraft and rocketry. The event will showcase a 1/4 functional scale model of the Curiosity Mars rover along with fun hands-on activities that will spark your imagination. Delve into some space art making for the whole family and learn things behave differently in the vacuum of space than they do under the influence of a Martian atmosphere. Come experiment with how different materials behave in a real vacuum chamber to understand why atmospheric pressure is so important! Music, beer, wine and food available 

Forget the holiday gingerbread house this season. Stop by our Studio 1 to make an edible Mars rover.  

Planetarium Shows 
(35 min) We’re going to Mars, and you can come with us! Are you ready for the adventure of a lifetime? Mars has sparked the human imagination for millennia, conjuring visions of supernatural deities, extraterrestrial civilizations, and otherworldly landscapes. And now, the detection of water has reenergized our imagination, focusing our attention on the planet next door to Earth in hope of finding unearthly life on the Red Planet. Come and join the greatest exploration in history, to Mars!

Introduction to Astrophotography

Have you ever wondered how astronomers take a picture of another galaxy or celestial object? In this presentation, you will hear how amateur astronomers produce these images. This includes the required equipment, what an imaging session looks like, and finally, an overview of processing data into a final image. Whether you are a casual observer or just getting started, this presentation will provide you insight into astrophotography. Former SMCAS president, Frank Seminaro, will give this presentation and also display some recent SMCAS member images. The presentation will be followed by a Q&A session with experienced SMCAS astrophotographers.

Speaker: Frank Seminaro, San Mateo County Astronomical Society

Telescope Makers Workshop
Chabot Space and Science Center
10000 Skyline Boulevard
Oakland, CA 94619-2450

The Chabot Telescope Maker's workshop reopens! Chabot's TMW is one of only a handful of regularly scheduled telescope making workshops in the U.S., and probably the world; it meets every Friday evening throughout the year, except Memorial Day weekend. It has been in operation since December of 1930, founded by Franklin B. Wright, and is currently run by Eastbay Astronomical Society member Rich Ozer, with help from other EAS members, Dave Barosso, Barry Leska, and others. The price of admission is FREE. All you have to do is show up, buy a mirror blank and a "tool" (typically around $100 - $200 depending on the size of the mirror) and start "pushin' glass!" We supply you with instruction, the various grits you'll need to first grind, and then polish and figure your mirror, and all the testing equipment needed. With a small bit of luck, you could wind up with a telescope that costs 1/3 or 1/4 the cost of a store-bought telescope, that is yet optically superior! It does take time - depending on how much time you put in on it, and other factors, it could take a few months.. But, it's a fun project, great for kids, and at the end you get a great telescope!

Enter from the main loading dock behind the main building.

Please be prepared with proof of vaccination and a mask. These are
Chabot Rules, which we always must adhere to.

If you have a project, bring it with you so we can assess next steps.
You can also bring any other equipment or literature you may have
questions about.

For more information call or email Richard Ozer at rrichozer1@... or phone (510) 406-1914.

Free Telescope Viewings

Join Chabot astronomers on the Observatory Deck for a free telescope viewing! Weather permitting, this is a chance to explore stars, planets and more through Chabot’s historic telescopes. Chabot’s three large historic telescopes offer a unique way to experience the awe and wonder of the Universe. Our observatory deck offers breathtaking views 1,500 feet above the Bay. Three observatory domes house the Center’s 8-inch (Leah, 1883) and 20-inch (Rachel, 1916) refracting telescopes, along with a 36-inch reflecting telescope (Nellie, 2003).

Are the skies clear for viewing tonight? Viewing can be impacted by rain, clouds, humidity and other weather conditions. Conditions can be unique to Chabot because of its unique location in Joaquin Miller Park. Before your visit, check out the Weather Station to see the current conditions at Chabot.

Foothill Observatory Open 1st and 3rd Fridays + Saturdays

The Foothill College Astronomy Department and Peninsula Astronomical Society (PAS) have reopened public viewing programs at Foothill College Observatory on the following schedule:

·       1st and 3rd Friday of each month, from 9 p.m. to 11 p.m. for star gazing

·       1st and 3rd Saturday of each month, from 10 a.m. to noon for solar viewing

Since we are still dealing with COVID, we are adopting the following guidelines to enable safe operation of the Observatory for both our public visitors and our PAS operators.  We ask that visitors please agree to complying with these guidelines before visiting the Observatory, and to direct any questions to
1.    Full vaccination against COVID-19 is required to visit the Foothill College campus — This is a College requirement detailed on the Foothill College COVID-19 Behavioral Expectations page.

2.    Mask usage is required anytime visiting the Foothill College campus — This includes the Observatory, per the same college policy linked above in item 1. 

3.    The number of visitors allowed inside the Observatory is reduced — To avoid overcrowding within the limited space, please wait outside the observatory until a PAS telescope operator lets you and your group inside. Once your group is done viewing through the telescope, you will exit the Observatory so that a new group may enter.
