Australia’s newest radio telescope

Fundamental questions about the Universe are set to be answered as a new radio telescope in outback Western Australia comes online, using multiple beam radio receiver technology to view the sky with unprecedented speed and sensitivity.

The Australian SKA Pathfinder (ASKAP), CSIRO’s newest telescope, uses innovative phased array feed receivers, also known as ‘radio cameras’, to capture images of radio-emitting galaxies in an area about the size of the Southern Cross—far more than can be seen with a traditional radio telescope.

Wide open skies for Australian astronomy

CSIRO’s Australian Square Kilometre Array Pathfinder (ASKAP) telescope is already booked out for much of its first five years of data gathering, even before it formally begins early operations in 2013.

More than 400 astronomers from over a dozen nations have already signed up to look for pulsars, measure cosmic magnetic fields, and study millions of galaxies.

ASKAP was built at the specifically radio-quiet Murchison Radio-astronomy Observatory (MRO) in Western Australia as a technology demonstrator for the $2 billion Square Kilometre Array radio telescope.

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 built at the remote, radio-quiet Murchison Radio-astronomy Observatory (MRO). Continue reading Telescope of tiles

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, CSIRO’s ASKAP, is expected to accumulate more information within six hours of being switched on than all previous radio telescopes combined.

Such gargantuan streams of data require serious management, and that will be one of the jobs of the $80 million iVEC Pawsey Centre in Perth, which is due to be completed in 2013.

Australia’s SKA demonstrator already booked out

The sky's no limit with ASKAP

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 millions of galaxies, and more.

SkyMapper’s 268-megapixel camera

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.
