Looking for life, dark energy and the beginning of time
Southern Africa, Australia and NZ are to share the Square Kilometre Array – a giant radio telescope that will consist of thousands of separate radio dishes and other antennae spread across an area the size of a continent.
We’ve pulled together links to our stories and to other sites about SKA. Feel free to use our stories as raw material for your own accounts.
“The South African team ran a strong campaign appealing to the heart and souls of the decision makers. At meetings around the world they talked about how locating this science icon in Africa would act as beacon for science in what we in the West once called the Dark Continent. And they clearly impressed the site committee with the quality of their science,” says Niall Byrne, science writer and creative director of Science in Public.
“As an Australian I was secretly hoping that a compromise would be reached that would bring benefits to both continents. It’s a good result for the world, even if it complicates the lives of the astronomers and engineers who have to make it happen.”
“Last year we produced a collection of stories on Australian astronomy. They include an account of the links between the Battle of Britain, the moon landings and the SKA; and descriptions and photos of the facilities that have already been built. Here are some highlights.” Full details at the links below.
Why are we good at radio astronomy?
Radio waves were detected from the Sun and our galaxy before World War II. But radio astronomy—the use of radio waves as a tool for studying the cosmos—developed rapidly only after the war powered by research into radar. Australia was one of the pioneers, led by CSIRO’s forerunner, the CSIR. At the end of war, CSIR’s radio group stayed together to continue research in peace time uses of radio waves. CSIRO’s research grew rapidly with the creation of the Parkes radio telescope, known locally simply as ‘The Dish’, and later the Australia Telescope Compact Array built for Australia’s Bicentenary.

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 millions of galaxies, and more.
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.
