Australia Involved in New Telescope Technology

Australia continues to make great strides in new developments thus helping the world move forward. For such a small country in population terms it is in the big league.

CSIRO as always is at the forefront, leading the research team. Recently in Western Australia the SKA Pathfinder radio telescope (ASKAP) took a photo of the sky with much improved clarity and over a larger area than ever before. It is much faster as well.

Professor Brian Boyle said a new era for astronomy has arrived. ASKAP is part of the International Square Kilometer Array (SKA) with South Africa. Scientists are so impressed they are touring Europe explaining their results.

The aperture-synthesis telescope is the first of its type to be used. CSIRO's phased array has perfected the system. Performance is much better than current telescopes. Photos are created from radio waves.

A massive area of 10 square degrees is covered, which is 50 times bigger than the a full moon. The "snap" is just that: the series of nine overlapping pictures are taken and composed into one photos in one snap. However, the time to scan takes 12 hours. The telescope "freezes" in one position while the stars and Earth continue to move. Surveying of the sky is at least 50 times faster than current telescope systems and will be made even quicker in the near future.

New Chip For Proposed Square Kilometer "Telescope"

CSIRO has made a new chip for the Square Kilometer Array (SKA). A decision on where the SKA will be located, Australia or South Africa, has yet to be made. The new telescope array will analyse data from small radio dishes spread over a 3,000 kilometer area.

Silana is working with CSIRO on the chip made of silicon-on-sapphire (SOS). It is designed for the mid-band range (500MHz - 2GHz). The unit is a one piece integrated circuit board replacing the multi-unit board previously used for this process.

The new SKA "telescope" will be the largest ever built and it will give high resolution images of distant parts of the universe. Though the array will evaluate a wide range of frequencies, the mid-range is important as it is the emission line for hydrogen which gives the distribution of galaxies and stars.
