The Orange County Astronomers is a non-profit organization whose main purpose is to spread knowledge and appreciation of the science of astronomy. Just a beginner? No problem!
Let There Be Light: Finding the Earliest Galaxies
A few hundred million years after the Big Bang, the hydrogen in deep space was ionized into its component protons and electrons. Theorists speculate this landmark event was caused by the birth of the first galaxies. Can powerful telescopes, probing back in cosmic history, directly witness this event? Large telescopes have already traced the evolutionary history of galaxies back to when the Universe was 1 billion years old. The first results from the Wide Field Infrared Camera onboard Hubble Space Telescope give us our first glimpse at primitive stellar systems at even earlier times. Professor Ellis will address the progress and challenges of this fundamental quest for our origins, and discuss the future prospects with the next generation of giant 30-40 meter aperture ground-based telescopes.
Richard Ellis is the Steele Professor of Astronomy at the California Institute of Technology (Caltech) in Pasadena. He is an observational astronomer who studies the distant Universe with a variety of facilities including the Hubble Space Telescope and the twin Keck 10 meter telescopes in Hawaii.
Professor Ellis obtained his Ph.D. at Oxford University in 1974. As a young researcher he established a major astronomy group at Durham University and later became the Director of the Institute of Astronomy at Cambridge University. He emigrated to the United States in 1999 where he has played a leading role in developing the science case and international partnership for the Thirty Meter Telescope: an ambitious next generation ground-based telescope to be completed in 2020.
Ellis' research interests include cosmology - the form and content of the Universe as a whole - and the evolution of galaxies over cosmic time. He has been influential in making many discoveries in these areas and is one of the world's most highly-cited astrophysicists.
His awards include the Gruber Cosmology Prize and the Gold Medal of the Royal Astronomical Society. He is a Fellow of the Royal Society and was awarded the title of Commander of the British Empire by Queen Elizabeth in 2008 for his contributions to international science.
"What's Up?" in this month will be presented by Chris Butler
Monthly General Meeting
The OCA has a general meeting held on the second Friday of every month* at Chapman University.
These meetings are free and open to the general public.
The meetings take place in The Irvine Lecture Hall with seating for approximately 250 people.
The Irvine Lecture Hall (located adjacent to the Hashinger Science Center) is near the south east corner of the campus
and the nearest cross street is East Palm Ave and North Center Street.
The meetings start promptly at 7:30 PM.
The basic agenda, with approximate times, is as shown below.
7:00 PM - 7:30 PM Pre-meeting Slide Show
Arrival of audience. This presentation includes recent astronomical photographs taken by OCA members.
7:30 PM - 7:45 PM Club Announcements
Usually presented by the OCA Secretary, Bob Buchheim.
7:45 PM - 8:15 PM "What's Up?"
Usually presented by OCA Member and Space Artist, Chris Butler.
8:15 PM - 9:15 PM Main Talk
Speakers are often from JPL/Caltech and other major educational and astronomical institutions.
The level of the talks are usually appropriate for anyone who has an interest in this hobby.
9:15 PM - 9:30 PM Refreshments
Break Donuts, coffee, soda are available for a small donation.
9:30 PM - 10:00 PM "Ask an Astronomer"
Anyone can stay behind and ask a panel of experts any burning question related to this hobby.
