Welcome to the Tri-Valley Stargazers Astronomy Club's web site. There is a lot
of information here on the many activities of the Tri-Valley Stargazers
(TVS). Learn why you should join the club to get the most out of your
amateur astronomy hobby in the east San Francisco Bay Area.
The Latest News & Upcoming Events
In 2018, an Ariane 5 rocket will blast off from Earth and begin a long, 1 million mile
journey to the second Sun-Earth Lagrange Point. Its cargo will be arguably one
of the most expensive and precious instruments NASA has ever made: the James
Webb Space Telescope (JWST). As the successor to the Hubble Space Telescope,
JWST will peer deeper into the universe than ever before. It will unlock secrets that
we haven't even begun to imagine. In this short talk, Dr. Lance Sims will give an overview of the
astounding engineering challenges behind JWST and describe some of the scientific
questions it will try to answer. He will also try to convey that all of his previous
statements depend on mission success, which is by no means guaranteed.
Lance Simms is a physicist/engineer at Lawrence Livermore National Laboratory.
He received a B.S. in Physics from University of California: Santa Barbara in 2003
and a Ph.D. in Applied Physics from Stanford in 2009. His Ph.D. work focused on
the application of Hybrid CMOS imagers in astronomy. Nowadays, he loves working
with whatever detectors he can get his hands on (infrared, visible, X-ray, you
name it), and he currently characterizes and programs imagers for optical payloads
on small satellites.
H2O Open House
Our next open house is scheduled for Saturday, May 20th at the club's dark sky site,
Hidden Hill Observatory
Anyone can come to our open houses, not just club members; but you cannot go
there without an escort. We will meet at the corner of Mines and Tesla Roads
at 6:30 PM, then caravan to the site on a drive that takes about 50 minutes.
The admission is $3/car; please bring the exact amount. There is no gas on
the way, so be sure to gas up before leaving. The site is essentially in the
wilderness, so there is no electricity and water, and there are only a couple
of pit toilets. Cell-phone reception is iffy at best. While there is a
picnic table there, you really should bring your own chair. If you need to
see what you are doing, bring a red LED flashlight, not a white-light
flashlight. And use masking tape over your car door and interior lights, or
pull the fuse. If you don't have a scope, you can always find someone who is
willing to let you look through theirs. And don't forget to bring your
binoculars. Expect to stay until about midnight and get back to Livermore at
around 1:00 AM.
