Adjunct Professor David Malin
Australian Astronomical Observatory
& RMIT University
Abstract: When the photographic plate replaced the eye as the astronomical detector of choice 120 years ago, it revolutionised astronomy, much as the invention of the telescope had heralded a new era, 280 years before. It was soon realised that photography could detect radiation from the stars that was invisible, revealing new and exciting phenomena. With this came an understanding of the nature of stars, nebulae and galaxies and for the first time their astonishing colours were revealed. In this profusely illustrated talk I will briefly review the rich history of imaging in astronomy, from Galileo to modern times.
Bio: David Malin has been involved in scientific imaging all his working life. He joined the Anglo-Australian Observatory (AAO, now the Australian Astronomical Observatory) as its Photographic Scientist in August 1975, shortly after scheduled observations began on the then-new, 3.9m Anglo-Australian Telescope (AAT) in June 1975. He is also now Adjunct Professor of Scientific Photography at RMIT University in Melbourne. He was born in England and trained as a chemist, working for many years with a large international chemical company in the north of England. There he used optical and electron microscope and X-ray diffraction techniques to explore the very small before turning his attention to much larger and more distant things in Australia.
David Malin worked for 26 years at the Anglo-Australian Observatory (now the Australian Astronomical Observatory) as photographic scientist and astronomer. There he developed hypersensitising processes which can give enormous gains in speed to the photographic materials that were used in astronomy. He also invented new ways of revealing information on astronomical plates, a speciality which has given him an international reputation.
David Malin has published over 120 scientific papers and a similar number of popular articles on astronomy and photography, as well as nine books. He is also a well-known and entertaining lecturer on these and related topics. The Invisible Universe (Bulfinch Press/Little, Brown and Company, 1999) is a large format celebration of the beauty of the night sky, a subject increasing explored in his gallery exhibitions. He was also scientific advisor for Heaven and Earth (Phaidon, 2002) a profusely illustrated work that uses scientific pictures to explore all scales from the atomic to the cosmic. More recently, he was commissioning editor for the Scientific Imaging section of Elsevier's well respected Focal Encyclopedia of Photography. His latest book (July 2009) Ancient Light, is a portrait of the Universe in black and white.
David Malin's contributions to photographic science and astronomy have received international recognition, including honorary degrees from two Australian universities:

Arkaroola: Safeguarding a Geological Treasure
Thursday 7th of February 2013 at 7.45pm
Mawson Lecture Theatre
Department of Geology
University of Adelaide (off Victoria Drive)
Arkaroola Wilderness Sanctuary
Marg Sprigg, daughter of prominent SA geologist Reg Sprigg AO, is looking forward to speaking about the Arkaroola Wilderness Sanctuary in the northern Flinders Ranges – a bit of its past history and some plans for the future now that the Arkaroola Protection Act is in place safe-guarding Arkaroola from mining.
Marg, a graduate in geology from Adelaide University, was fortunate to traipse around Australia with her father through much of her formative years, giving her great respect for Arkaroola’s varied geology that includes the Mt Painter Inlier with its unique features such as today’s Paralana Hot Springs and its fossil hot spring equivalent preserved at Mt Gee. The Inlier is wrapped by Adelaidean sediments that include the greatest thickness known of Sturtian tillites, laid down during the time of ‘Snowball Earth’. But after the ice retreated an ancient ‘barrier’ reef of stromatolites, and other organisms of unknown affinity (but possibly sponges) was constructed. Reef building kept pace with sea level rise such that the reef, from its base in deep water Tapley Hill slates rises to one kilometre in height.
Marg would love to take you for a pictorial wander through some of Arkaroola geological delights.
The meeting will be held in the Mawson Lecture Theatre, Mawson Laboratories, corner of Victoria Drive and Frome Road, University of Adelaide at 7.45 pm. Members and visitors are warmly invited to attend. We are obliged for security reasons to keep the front door of the building locked, so please use the special Field Geology Club doorbell to the side of the door for admittance.

Stockport Observatory Public Star Party
Saturday, 16th of February 2013 at 8:30pm (weather permitting)
Observatory Road, Stockport, S.A.
About the observatory:
Stockport Observatory is located in the small town of Stockport (6kms north-east of Hamley Bridge) approximately 80kms north of Adelaide. It provides a convenient astronomical facility away from the light pollution which surrounds Adelaide (population 1 million).
The Society owns two large observatories in Stockport. One of them houses a 12-inch (30cm) Ritchey-Chrétien, while the Charles Todd Observatory houses the Society's largest telescope at present - the Jubilee Telescope. Stockport Observatory houses three permanently-mounted telescopes as well as some small portable ones.
The Jubilee Telescope is a 20-inch (0.5 metre) Newtonian-Cassegrain reflecting telescope that was built with the assistance of the state's Jubilee 150 Board in 1986. The telescope is computer-controlled and equipped with a ST-6 CCD camera for digital imaging of the night sky. The smaller observatory houses a computerised 12-inch (30cm) Ritchey-Chrétien reflecting telescope. A slide-off roof observatory houses a popular 15-inch (40cm) Newtonian reflecting telescope. The telescopes are used for projects within the Society and to show visitors the beauty of astronomical objects in the southern skies.
In addition to the main observatory buildings, the Stockport site also contains three telescope pads (all with power), a furnished hut with sleeping accommodation and amenities, a large shed seating around 30 people for lectures and slide shows, a BBQ area, shower and toilet facilities, and an off-site car park. Viewing nights will only proceed if the weather is suitable. If in doubt, confirm by visiting our web site or calling (08) 8338 1231 before travelling to any observing session.
There is no need to book - just turn up on the night at pay at the gate
Admission: Adults $10, Children $2
Members: Free For further details visit: http://www.assa.org.au/events/public-viewing-nights/stockport-observatory-star-party/

'Asteroids, Meteorites and the early Earth'
Dr Victor Gostin (University of Adelaide)
Abstract: Order and disorder in planetary systems. Origins and nature of asteroids and meteorites leads to a better understanding of our Earth history with its water and life.
Bio: Assoc. Prof. Victor Gostin, M.Sc. (Melb), PhD (ANU). Victor Gostin is a retired Associate Professor and an Honorary Visiting Research Fellow in Geology and Geophysics at the University of Adelaide, Australia. A graduate of Melbourne University with a PhD from the ANU, Canberra, Victor lectured in earth sciences at Adelaide University from 1970 to 2001. His scientific interests include the origins and evolution of the solar system and of life, meteorite impacts, earth history, environmental geoscience and the effects of natural phenomena on the course of human history. His other interests include sketching the Australian outback. Victor is keen to popularise earth and planetary sciences to the community through lectures and radio. As a result of recognising and proving that a unique rock layer in the ancient rocks of the Flinders Ranges, South Australia, was derived from a giant meteorite impact, he has been honoured by having an asteroid named after him (3640GOSTIN).
‘The Tektite Enigma’
Dr Olga Gostin (University of South Australia)
Abstract: Black glassy lumps, "buttons" and "dumbells" found scattered over southeast Asia and south to Australia (=Australites) are believed to have originated from a large asteroidal impact probably into the tropical Laos-Cambodia region. Although some dating suggests this event occurred 780,000 years ago, controversies remain for a possible younger age. Aboriginals have used these objects and have stories of their origin.
Bio: Dr Olga Gostin, BA Hons (Wits), M.Env.St. (Adelaide), PhD (ANU). Of Belgian-Russian parentage, Olga Gostin graduated as a social anthropologist from the University of the Witwatersrand in South Africa. She obtained her PhD from the Australian National University in 1968 after completing research on the impact of Catholicism and cash-cropping on the Kuni of Papua. In 1993 she completed a Master’s degree in Environmental Studies at Adelaide University. For the past 40 years she has been connected with Australia’s first program offering tertiary education to Indigenous Australians at the University of South Australia. Olga is passionately interested in the dynamics of culture change, environmental issues and matters of social justice.
Tour of the Night Sky
Paul Curnow, B.ED. (University of South Australia)
Abstract: The night sky has fascinated people since the dawn of humankind. Australia is still fortunate in that it has relatively low levels of light pollution, which allows us some of the best night sky views in the world. We will take a guided tour of the brightest stars, the constellations, their mythology, and the way that other cultures like Aboriginal Australians perceive the celestial dance of stars above.
Bio: Bio: Paul Curnow (B.ED) is a council member of the Astronomical Society of South Australia and a former council member of the Field Geology Club of South Australia. He has been a lecturer at the Adelaide Planetarium since 1992 and was the recipient of the ASSA editor’s award for 2000, and then again in 2010. In 2002, he served as a southern sky specialist for visiting U.S. and British astronomers who were in Australia for the total solar eclipse. He is regarded as one of the world’s leading authorities on Australian Aboriginal night sky knowledge; and in 2004, he worked in conjunction with the Lake Erie Nature and Science Center Planetarium in Ohio, on the creation of a show that features Indigenous Australian stories of the night sky. In addition, Paul runs a number of popular courses for the general public that focus on the constellations, planetary astronomy, historical astronomy and ethnoastronomy, which primarily deals with how the night sky is seen by non-western cultures. He appeared as the keynote speaker at the inaugural 2010 Lake Tyrrell Star Party in Sea Lake, Victoria and recently returned from New Zealand after being a special guest speaker at the Carter Observatory in Wellington. Since 2012 - Paul has taken the role of lecturer for the Astronomy & Universe course (EDUC 1036) for the School of Education at the University of South Australia. Paul appears regularly in the media and has authored over 40 articles on astronomy.
