An astronomer and Aboriginal researcher will highlight thousands of years of serious star gazing when he discusses the astronomical knowledge and traditions of Aboriginal Australians next week at Charles Sturt University (CSU) in Albury-Wodonga. Dr Duane Hamacher from the University of NSW in Sydney will explore the relationship between astronomy and calendars, navigation, food economics and social structure in the lives of the first Australians. The free public lecture will be the first event in Albury as part of National Science Week for 2013, which is being coordinated by the Astronomical Society of Albury-Wodonga in conjunction with CSU. The event starts at 7pm on Tuesday 13 August in the CD Blake Lecture Theatre, CSU in Albury-Wodonga, off Elizabeth Mitchell Drive, Thurgoona.
