Wally Pacholka

Born in 1949 in Montreal, Wally Pacholka has been an avid amateur astronomer and astrophotographer since joining the Royal Astronomical Society of Canada in 1963. He is now a member of Orange County Astronomers in Southern California.

Pacholka specializes in landscape astrophotography of America`s National Parks and great natural landmarks. His celestial photography earned him TIME Magazine`s “Picture of Year” honors for his image of Comet Hale-Bopp in 1997. When Mars made it`s closest approach to Earth in history in 2003, he earned a second TIME Magazine “Picture of Year” award for his photograph of that event. BC-Hiking Queen Trail in Trees under Milky Way-850wpHe followed that honor with a LIFE Magazine “Picture of Year” for another Mars photograph that same year. LIFE Magazine`s 2007 issue of “America the Beautiful” includes one of Pacholka`s signature images. Over the years his scenic astro-landscape images have graced the pages of many other international publications including National Geographic, Newsweek, Encyclopaedia Britannia. NASA selected more than 25 of his images for their record of celestial events.

With many friends around the world as a result of his astrophotography, Pacholka appreciates the great opportunities astronomy offers in promoting peace and friendship among the peoples of the world.


Stephen W. Ramsden

Stephen W. Ramsden is the founder and director of the world’s largest hands on Solar Astronomy nonprofit-The Charlie Bates Solar Astronomy Project (  Named in memoriam to fellow veteran and former air traffic controller, CBSAP has 63 members in 7 countries and provides direct, hands on imaging and visual solar observation to over 150,000 students and adults per year.  Mr. Ramsden sees over 60 schools per year and over 80,000 students  annually in the United States.  The mission is simple…use the fascinating hobby of solar astronomy to expose as many people as possible to the endless, life improving possibilities inherent in the high tech sciences.


Dr Seth Shostak

    • Ph.D. astrophysics, California Institute of Technology, Pasadena, California
    • B.A. physics, Princeton University, Princeton, New Jersey

Seth claims to have developed an interest in extraterrestrial life at the tender age of ten, when he first picked up a book about the solar system. This innocent beginning eventually led to a degree in radio astronomy, and now, as Senior Astronomer, Seth is an enthusiastic participant in the Institute’s SETI observing programs. He also heads up the International Academy of Astronautics’ SETI Permanent Committee.

In addition, Seth is keen on outreach activities: interesting the public – and especially young people – in science in general, and astrobiology in particular. He’s co-authored a college textbook on astrobiology, and has written three trade books on SETI. In addition, he’s published more than 400 popular articles on science — including regular contributions to both the Huffington Post and Discover Magazine blogs — gives many dozens of talks annually, and is the host of the SETI Institute’s weekly science radio show, “Big Picture Science.”


Dr. Travis Orloff

A recent recipiant of a PhD in Planetary Science. Dr. Travis Orloff studies a landform called patterned ground that covers much of the surface of Mars. His research has placed limits on the timescale of patterned ground formation using crater age dating statistics and I have also placed constraints on a potential mechanism for boulder clustering on patterned ground.

Prior to recieving his PhD, Dr. Travis Orloff was a Graduate Student Researcher at the University of California Santa Cruz Department of Earth and Planetary Sciences where he took part in geological research of patterned ground terrain on Mars funded by NASA’s Mars Fundamental Research Project.

Dr. Orloff has had a number of publications such as, Possible mechanism of boulder clustering on Mars, Boulder Movement at high northern latitudes on Mars, Landscape evolution degrades the geologic signature of past glaciations.

In August 2013 he accepted a position as a Physical Sciences instructor at Los Angeles Pierce College.
