The Sydney Institute for Astronomy (SIfA) is a national and international leader in Astronomy and Physics, through cutting edge theoretical and observational research and the application of new technology for the next generation of instruments and telescopes. As well as being a research leader, SIfA is committed to excellence in postgraduate training and research-led undergraduate training.

SIfA astronomers obtain observational data from major facilities in Australia, overseas, and in space. We also operate our own radio telescope, the Square Kilometre Array Molonglo Prototype (SKAMP), while the Sydney University Stellar Interferometer (SUSI) is the major element in our broad program of high-resolution optical imaging. We also frequently receive observing time on the national facilities in Australia – the Anglo-Australian Telescope (AAT – optical) and the Australia Telescope National Facility (ATNF – radio).
