Although our Sun formed about 4.5 billion years ago, star formation is an ongoing process in our Galaxy: Dr Tyler Bourke, an astronomer at the Smithsonian Astrophysical Observatory, will explain how that process works in a free talk presented by the Faculty’s Astronomy Outreach program.

Dr Bourke will present the latest understanding of how stars such as our Sun form and how their birth environment affects their evolution.

Stars form from the collapse of interstellar clouds of gas and dust, forming disks in the process from which planets are formed, says Dr Bourke.

This process is mostly hidden from view at optical wavelengths. However, recent observations from space and the ground, primarily at infrared and millimetre wavelengths, penetrating the dusty birthsites, have revealed the formation process in unprecedented detail.

The talk is sponsored by the Harvard Club of Australia Foundation and Dr Bourke will be introduced by the President of the Harvard Club of Australia, Peter Hasko.

If the weather is suitable, telescope viewing may occur after the talk.
