Don Sweetnam of the Jet
Propulsion Laboratory will talk on ‘Genesis 10 years
after Earth Return’. The Genesis
satellite collected solar wind particles and brought them back
to earth, to give us direct samples from our sun - -and clues
to Earth's formation.

large is the observable universe? How do we measure its scale? Tim
Thompson (retired from NASA/JPL)
gave a talk on this expansive subject at our meeting in Novemer 2014.
guest speaker in October 2014 was Sami
Asmar, a project scientist at NASA’s Jet
Propulsion Laboratory. He described how radio signals between spacecraft
on solar system missions allow us to remotely investigate the interiors
of planets and satellites. Also discussed were the interiors of the
moon, Vesta, and the icy satellites of the outer planets, and the latest
space breakthroughs from Mars
Curiosity and ESA's Rosetta.
guest speaker in September 2014 was Steve Levin of JPL.
Dr. Levin is Project Scientist for NASA's Juno
Mission to Jupiter. Juno's experiments will tell us about the interior
structure of the gas giant. Dr. Levin also works on GAVRT,
a radio telescope that can be operated remotely by students and non-professionals.
June 2014, Roger
Caltech spoke about the major news story creating waves in the astronomy
world lately - the possible detection of gravity waves from the Big
In May 2014, Chris Bang explained how his company is
pursuing plans do do space exploration with unmanned flying vehicles,
which might one day be used to explore Mars and other planets or moons
with an atmosphere.
March, 2014, Fabio Altenbach discussed the bizarre
notions of distance and space in modern cosmology, in a way that harkens
back to some of our ancient cosmic concepts.
November 2013, Phil Korngut (Caltech/JPL) showcased
recent research - including his own -on measuring the Cosmic Background
Radiation, the relic energy from the Big Bang. He traced the progress
of our understanding, and explained how he is pushing forward on a new
frontier - the near infrared signals from the early universe.
October 2013, Tim Thompson gave a talk about the history
of photography. (Tim
Thompson received his degrees in physics from California State University
at Los Angeles; B.S. in 1978 and M.S. in 1987. He joined the Jet Propulsion
Laboratory technical staff in January 1981, and retired from JPL in
August 2013, Josh Simon, an astronomer at the Carnegie
Institution, gave an introduction to stars, including the Sun, and described
how they are responsible for producing nearly all of the chemical elements
in the universe today. Current theories, though, predict that the first
stars, which formed 13 billion years ago, may have been very different
from those being born now. He explained how the amount of heavy elements
in a star can serve as a clock indicating its time of birth, and then
described the results of recent searches for primeval stars in both
the Milky Way and nearby dwarf galaxies. Dr. Simon has made fundamental
contributions to the study of stars and galaxies in the early universe.
He has found some of the "darkest" galaxies in the universe,
so his work relates to dark matter.
In July 2013, Thor Dockweiler gave an update about

expedition and gave a talk about the Chinese space program and the success
of China's manned flight in June 2013.

Tim Thompson spoke about our deepest images of the
cosmos: The Hubble Deep Fields. One of the Hubble Space Telescope's
"greatest hits" was an image aimed at nothing in particular
-- just a typical slice of the sky.

of the Jet Propulsion Laboratory gave a talk entitled 'Black Holes:

In November 2012, former
"Telecsope in Education" 24-inch telescope operator and Astronomy
historian, Matthew B. Ota told the story of Edwin Emerson
Barnard, a 19th Century Astronomer who pioneered astrophotography. Barnard
came out of a destitute childhood in Civil War ravaged Tennessee to
become one of the most celebrated and respected astronomers of his time.
The lecture featured over 88 photographs of Barnard from childhood to
adulthood, including the telescopes he used, the observatories he worked
at, family photographs and his astrophotography.

Laderman gave a talk entitled "Bad Science Meets The Equator",
about his recent trip to Central America and the pseudo-science presented
to tourists there.
In May 2012,
Steve Vance of the Jet Propulsion Laboratory gave a
talk about Jupiter's moon, Europa, and theories about the composition
of its oceans. Also discussed was the possibility of future missions
to the icy moon.
