When the present upgrade is complete, the Sydney University Stellar Interferometer (SUSI) will be able to resolve objects the size of a beach ball on the Moon, says Mike Ireland of Macquarie University in Sydney. This large interferometer will be used to determine the dimensions—size, weight and velocity—of pulsating stars, hot stars, and massive stars. SUSI will also be involved in the search for binary stars and their planetary companions. Continue reading Seeing a beach ball on the moon
On a mountaintop in northern New South Wales sits a new telescope equipped with Australia’s largest digital camera. The Australian National University’s (ANU) SkyMapper facility has been established at Siding Spring Observatory to conduct the most comprehensive optical survey yet of the southern sky.
Fully automated, the telescope is measuring the shape, brightness and spectral type of over a billion stars and galaxies, down to one million times fainter than the eye can see.
CSIRO’s Dr John O’Sullivan, winner of the 2009 Prime Minister’s Prize for Science, is now working on the next generation of radio telescopes.
John’s latest efforts are directed towards the development of an innovative radio camera or ‘phased array feed’ with a uniquely wide field-of-view for the Australian SKA Pathfinder (ASKAP) radio telescope.
