6:30pm till about 8:30pm, first Monday of the month
in Sydney Observatory’s basement Discovery Room
We encourage new members to join, no experience is necessary!
Join the oldest operating astronomical group in Sydney. The group provides an opportunity for those interested in astronomy to share and broaden their interest in the sky. People at all levels are catered for – from beginners to serious amateur astronomers. Whether you want to listen to a lecture or discuss serious observing through a telescope, this is the club for you.
Meetings are held on the first Monday of most months and usually begin with brief reports on solar activity and other astronomical observations made during the month by club members, followed by either a presentation from a guest speaker or telescope viewing followed by a light supper. We provide information below about special presentations. There is a $2 fee for each meeting (to cover the cost of the light supper). Bookings are not required. Meetings conclude around 8:30pm.
Non-members are welcome to attend two meetings before deciding whether to become a member. (We ask only a $2 donation towards the cost of supper.) It is possible to join Sydney City Skywatchers on the evening or take home a membership form. Annual membership is $40 for lots of great benefits ($65 for family membership).

The dirty secrets of large galaxies
Presented by Geraint Lewis
No bookings required
Abstract: Large galaxies, like our own Milky Way, have a dirty secret; they got to their immense size by tearing apart and consuming their galactic companions. In this talk I will examine the evolution of galaxies over the history of the Universe, showing that such cannibalism is a natural part of galaxies growing up. I will also show that this cannibalism continues to this day, catching both the Milky Way and Andromeda in the act of consuming little galaxies that have ventured too close.
Biography: Professor Geraint Lewis was born in Old South Wales, and studied Physics at the Universities of London and Cambridge. Since completing his PhD he has worked at the State University of New York, Victoria University in Canada, and the University of Washington in Seattle. He then became a Research Astronomer at the Anglo-Australian Observatory before joining The University of Sydney in 2002 to continue his studies of cosmology and the evolution of the Universe. He currently holds an Australian Research Council Future Fellowship.

The link between the Pilbara and Mars in the search for life elsewhere
Presented by Malcolm Walter PhD FAA FGS Aust.,
Professor of Astrobiology, ARC Professorial Fellow, University of New South Wales, Sydney
The oldest convincing evidence for life on Earth is found in the Pilbara region of WA. Decades of experience there have taught us how to find evidence of microbial life. The rocks in the Pilbara are the same age as when Mars was ‘warm and wet’, more that 3 billion years ago. So the information we have gleaned from the Pilbara is now guiding the search for life on Mars. Professor Walter will discuss the latest results from both planets.
