Next General Meeting

Saturday, January 26, 2019
7:30 P.M.

Galileo Room

Chabot Space and Science Center

Our Speaker is Dr. Dan Weisz, Assistant professor of Astronomy, UC Berkeley.

Resolving the Local Universe with the Hubble and James Webb Space Telescopes

Most galaxies are so far away that they appear to us only as faint smudges. However, for galaxies that reside in our Galactic neighborhood, the clarity and sensitivity of the Hubble Space Telescope transforms them from smudges into collections of individual stars. These observations allow astronomers to study how galaxies form and evolve one star at a time. In this talk, I will highlight some of the amazing science and images produced by Hubble observations of local galaxies from the past three decades. The pinnacle of these studies is the Panchromatic Hubble Andromeda Treasury (PHAT) program, an 800 hour Hubble survey of our sibling galaxy Andromeda, and one of the largest Hubble programs ever conducted. I will describe the PHAT survey and its scientific impact. I will discuss plans for James Webb Space Telescope, which will succeed Hubble as the most sensitive telescope in existence following its launch in 2021.

Dan Weisz is an Assistant Professor of Astronomy at UC Berkeley. He is an observational astronomer who primarily uses the Hubble Space Telescope to resolve nearby galaxies to study a wide range of phenomena ranging from dark matter to how stars and galaxies form and evolve. He has received national and international recognization for his research, including fellowships from the Alfred. P Sloan and Alexander von Humboldt Fellowship Foundations. As principle investigator of the James Webb Space Telescope Early Release Science Program for Resolved Stellar Populations, Dan will be one of the first people to use the James Webb telescope.

Prior to joining the faculty at UC Berkeley in 2016, Dan was a Hubble Fellow at the University of Washington and UC Santa Cruz, where he studied the smallest galaxies in the Universe, while also helping lead the PHAT program. He was awarded his PhD in astrophysics from the University of Minnesota in 2010. Dan attended UC Berkeley as an undergraduate, receiving degrees in physics and astrophysics in 2004.

Special Events

Barcroft High Altitude Observing (EAS members only): Nights of Monday July 29th – Saturday August 3rd.

Each year, EAS runs an excursion to UC Berkeley’s Barcroft High Altitude Research Station in the White Mountains above Bishop, CA.
This is a total of 6 possible nights. Everyone needs to leave by noon on Saturday.

At 12,000 feet, with often bitterly cold temperatures and miles of gravel and shale roads to traverse, this excursion is not for the faint of heart. The facilities, however, are exceptional. Food and lodging is included. Oxygen is not! To reserve your spot, you must be an EAS member, and you need only click the button below to pay for your intended stay. For detailed information, download our overview of the Barcroft event by clicking here. Reserve your spot via Paypal below. (Note that those staying through the night of August 3rd will be leaving on Sunday the 4th.)

Telescope Makers Workshop

The Telescope Maker’s Workshop is one of few regularly scheduled such workshops in the world! Every Friday from 7 to 10 PM, amateur telescope makers from the bay area meet at the Chabot Space & Science Center and learn how to grind, shape, polish, and figure mirrors for reflecting telescopes, under the guidance of EAS volunteers. The workshop is free; participants pay only for the mirror blanks and grinding tools, which generally cost between $100-$300, depending on the size of the mirror. All the instruction, grinding grit, testing equipment, and camaraderie is free of charge! For more information, email Richard Ozer at pres@eastbayastro.org, or come by the workshop any Friday to see what it’s all about.


EAS sends volunteers to schools, libraries, and anywhere curious aspiring astronomers gather. EAS volunteers bring their own equipment or borrow telescopes. Students, parents, and teachers are always thrilled to look through the telescopes and ask questions. You’ll meet all sorts of interesting people and provide a unique and inspiring experience to kids and parents who may have never looked through a telescope before. Find our next event on the calendar above.

Inquire about and request visits by e-mailing EAS Outreach Coordinator Raymond Howard at outreach@eastbayastro.org. Visit our outreach page to find out about upcoming events.

Members Only Viewing Nights (MOVN)

Once a month, we schedule a Members Only Viewing Night at the Chabot Telescope Deck for both EAS and Chabot members. This is our opportunity to look through Chabot’s historic instruments and research telescope, as well as bring our own equipment to share in a more quiet venue. The schedule for MOVN appears in the event calendar below.
