Sydney: Australian data experts join global efforts in the world's largest sky survey as Chile's Vera C. Rubin Observatory commences operations, imaging the entire southern sky every few nights. The observatory's Legacy Survey of Space and Time (LSST) will generate an unprecedented 20 terabytes of raw data each night, experts said.

According to Namibia Press Agency, a partnership between Macquarie University's Australian Astronomical Optics (AAO) and Swinburne University of Technology's Center for Astrophysics and Supercomputing will see Australian teams host and process more than seven petabytes of data annually. This collaboration operates under the Astronomy Data and Computing Services initiative, with nodes at Macquarie, Swinburne, and Curtin University, representing Australia's in-kind contribution to the LSST via agreements with Astronomy Australia Limited and the Rubin Observatory.

The Australian team is leading the development of robust software to manage Rubin's massive data flow, enabling global astronomical access. "It's a huge volume, most astronomers might deal with 20 terabytes of data over a year, rather than in one night," said Simon O'Toole, head of Research Data and Software at AAO. O'Toole expressed excitement about "capturing the universe in motion, everything from stars exploding and neutron stars colliding, to black holes merging."
