Telescope of tiles

Far outback in Western Australia, 32 tiles—flat, stationary sensors—each carrying 16 dipole antennas have begun collecting scientific data. These first tiles will ultimately form part of a much bigger array of 512 tiles, the Murchison Widefield Array (MWA)—Australia’s second Square Kilometre Array (SKA) demonstrator project. Like CSIRO’s Australian SKA Pathfinder (ASKAP), the MWA is being [...]

Managing a data mountain

The world’s largest telescope, the Square Kilometre Array (SKA), is expected to generate more data in a single day, than the world does in a year at present. And even its prototype, the Australia SKA Pathfinder (ASKAP), is expected to accumulate more information within six hours of being switched on than has been stored by all previous radio telescopes combined.

Such gargantuan streams of data require serious management, and that will be the job of the $80 million Pawsey High-Performance Computing Centre for SKA Science in Perth. Contracts for the construction of the building to house the Centre are expected to be let in December, 2010.

Australia’s SKA demonstrator already booked out

It’s not due to begin operating until 2013, but astronomers from around the world are already lining up to use CSIRO’s Australian Square Kilometre Array Pathfinder (ASKAP). In fact, the first five years of ASKAP’s operation are already booked out, with ten major international Survey Science projects looking for pulsars, measuring cosmic magnetic fields, studying [...]

Putting Einstein to the ultimate test

Einstein’s theories predicted them, and they could be everywhere throughout the universe. But they’ve never been directly detected. They are gravitational waves, unseen “ripples” in the fabric of space and time.

Scientists using CSIRO’s Parkes radio telescope are leading the way in trying to find them, by studying signals coming from pulsars.

Pulsars are the collapsed cores of giant stars that have exploded. Spinning at up to hundreds of times per second, they emit highly-regular radio pulses that appear to flash on and off like a lighthouse. And that’s the key.

Nurturing super astronomers at home

Advanced telescopes need advanced astronomers to run them. Australia is matching the millions of dollars it is investing in new telescope technology with funds to help train the rising stars of Australian astronomy. “We’ve had big investments in infrastructure, and now we need young scientists with the expertise to use them,” says Elaine Sadler, professor [...]

The destruction of a star

You have to be well prepared, quick and lucky to take a picture of an explosion, especially if that explosion occurred 11 billion years ago in a remote part of the Universe. Having the right equipment, plus friends in high places, certainly helps. And that’s exactly what the Zadko Telescope—managed by the University of Western [...]

From mapping a continent to surveying the Universe

Australia’s first observatory was built on the shores of Sydney Harbour by Lieutenant William Dawes of the First Fleet, on the point where the southern pylon of the Sydney Harbour Bridge now stands. Optical astronomy was essential for maritime navigation, and for providing precise location measurements for surveying the new continent. The country’s first major [...]

Australian farmers bring climate research to the paddock

Leading grain farmers are guiding climate researchers as part of Australia’s Climate Champion initiative. They hope the results will help farmers to adapt to Australia’s increasingly challenging and variable climate. Scientists supported by the Managing Climate Variability program asked the farmers about what they needed to know about climate in their areas—what forecasts and predictions [...]

Seeing fish through rocks

Dr Kate Trinajstic has used synchrotron light and CT scanning to see through rock, in the process discovering how ancient fish developed teeth, jaws and even a womb. Her work is increasing our understanding of how life on Earth evolved.
