Since its inception in 1965, the Molonglo Observatory Synthesis Telescope has been owned and operated by the University of Sydney. Originally built as the Molonglo Cross, the telescope has two huge cylindrical arms that stretch across the Molonglo valley, east of Canberra.

The University of Sydney is now ushering in a new era for the Molonglo Observatory Synthesis Telescope (MOST), announcing major upgrades to the instrument. From 2015, 50 years since the telescope started work, it will commence regular science observations as part of the UTMOST project in collaboration with Swinburne University, funded primarily by the Australian Government.

Facilitated by the Australian Research Council Centre of Excellence for All-Sky Astrophysics (CAASTRO), the University of Sydney, Swinburne University and CSIRO have formed an historic partnership to carry out the million dollar update of MOST.

While the structure of the telescope will be unchanged, a new supercomputer backend will allow astronomers to handle up to 22 gigabytes of data per second. This is entering the domain of big data, with smart electronics and clever software programs to process data in real time. Having directed the Molonglo telescope for more than a decade, Professor Anne Green from the School of Physics said the upgrade would be game-changing.

The major redevelopments to the Molonglo Telescope will deliver new and exciting capabilities - Professor Anne Green.

"For almost a decade, fast radio bursts (cosmic radio signals that last just a few milliseconds) have mystified astronomers. With the upgrade to Molonglo, we will have the opportunity to hunt for the mysterious bursts. We don't know where they are or what they are, but with this new capability we have an excellent opportunity to answer these questions."

Over its lifetime, the telescope has been funded mainly by the Australian Research Council and the University of Sydney. In recent years the NSW State Government has also provided funding, through its Science Leveraging Fund.

The University's Deputy Vice-Chancellor (Research) Professor Duncan Ivison, the Head of the School of Physics Professor Tim Bedding and Professor Anne Green were among the guests who attended the 50th anniversary celebrations and launch of upgrades at the Molonglo Observatory.
