    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. 

    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. See: http://fraknoi.com for more information about his work.

    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.

    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.

    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.

    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.

    Asteroid Mining: Stepping Stones to Solar System Exploration

    Since its inception, NASA has promoted a vision of space exploration that involves missions and outposts within the inner solar system with supplies delivered from Earth's surface, the Moon, or Mars. Recent research suggests an additional scenario in which humans live in space supported by resources extracted from asteroids, beginning with the most accessible Near Earth Objects (NEOs). NEOs are a cost-effective approach because they contain available, exploitable extraterrestrial resources that are delivered to the inner solar system by gravitational perturbations from the planets, they have been naturally preprocessed into objects the ideal size for industrial operations, and they contain critical materials for cost-effective self-sustaining activities in space.

    The James Webb Space Telescope: Shedding light on Dark Matter and Dark Energy



    With the James Webb Space Telescope (JWST), cosmologists now have a power tool in their hands to look deeper into the mysteries of our Universe than ever before. In this lecture, Dr. Birrer will lay out outstanding questions in cosmology and describe how JWST is uniquely positioned to advance our current understanding of dark matter and dark energy. Specifically, he will discuss how JWST will probe dark matter based on its impact on galaxy formation and from the observed gravitational lensing effect caused by this mysterious matter component. Dr. Birrer will also highlight key programs that utilize JWST to measure the Hubble constant, a parameter to characterize the expansion of the Universe. He will close the talk by previewing some early results from JWST, which the scientific community and the general public are eagerly awaiting.

    The Sun is Not Always Happy: Space Weather and the Question of Human Survivability - Livestream

    On October 27th 2022 NASA captured a now-famous image of the Sun “smiling” on its solar system [see image above]. But the Sun is not always happy! It can unleash violent “space weather” -- storms that can radiate X-rays and even gamma rays into space, send giant clouds of magnetic plasma slamming into the Earth and other planets, and spray firehoses of charged particles throughout interplanetary space. On Earth, we are mostly protected from the Sun’s wrath by our magnetic field and atmosphere, but astronauts venturing to the Moon and Mars will be vulnerable to these potentially deadly solar storms. Dr. Berger will discuss our current understanding of the interplanetary space environment, describe some extreme space weather events in history, and examine how well we can currently predict space weather and its impacts as we venture beyond our planet.

    Tom Berger is the Executive Director of the University of Colorado’s Space Weather Technology, Research, and Education Center, which combines traditional space physics research with technology and education to bridge the wide gap between research on the Sun and operational space weather forecasting. He was formerly the director of NOAA’s Space Weather Prediction Center, helped develop the world’s largest solar telescope on the island of Maui (the Daniel K. Inouye Solar Telescope), and has been a co-investigator on international missions to study changes in the Sun’s magnetic field.

    Solar Observing


    It’s there for us year round, lighting our days and providing energy for our lives, so maybe it’s time to give it a closer look. Join SJAA for amazing and detailed views of the Sun, and be assured that we’ll be using special telescopes that will keep your eyeballs perfectly safe.

    We’ll have white-light telescopes with dense solar filters that reveal sunspots. Further, we’ll show you hydrogen-alpha telescopes that isolate a very specific color of red that reveals prominences (often thought of as solar flares) and intricate texture within the Sun’s chromosphere (its atmosphere).

    We can also share with you a little about how the Sun works and how complex magnetic fields drive the number of sunspots and prominences that we’ll see on a given day.

    Around 1:45, we'll have a short, informal introductory talk, and at other times, you can enjoy the views and ask questions about the Sun, telescopes, or astronomy in general.
