When complete, they’ll be able to pick up radio signals from the time when the first stars in the universe formed.

China has a large community of astronomers awaiting the construction of new telescopes to study pulsars.When CSIRO pulsar researcher Dr George Hobbs described the high-quality data stored in the Parkes Observatory Pulsar Data Archive—which is openly available—it led to Australian pulsar data being the basis of collaboration between Chinese and Australian pulsar researchers. And they have already published several papers on what they have discovered. The archive is also serving as a major resource in an international search for gravitational waves.
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.

Theoretical physicist Prof Stuart Wyithe is one of the world’s leading thinkers on the Universe as it was 13 billion years ago, when there were no stars or galaxies, just cold gas.
In the next few years astronomers will learn much more as powerful new telescopes come online.
Enormous collapsing clouds of cosmic gas and dust may yield clues on how massive stars form, which is an enduring mystery of astronomy.
One such cloud, called BYF73, has been studied by a research team using CSIRO’s Mopra radio telescope. Peter Barnes, an Australian researcher working at the University of Florida in the US, leads the team. The massive hydrogen cloud is collapsing in on itself and will probably form a huge cluster of young stars. Continue reading Mega star nursery gives birth to new knowledge
At the centre of a nearby galaxy lurks an object of huge interest, a super-massive black hole. CSIRO scientists have used their radio telescopes to take a picture of the galaxy surrounding it, a task some thought could not be done, because of the sheer size and radio brightness of the scene. The image of Centaurus A took about 1,200 hours of observations and a further 10,000 hours of computer processing to put together, but the work is already beginning to bear fruit.
“We didn’t generate this image just to make a pretty picture,” says lead scientist Ilana Feain of CSIRO Astronomy and Space Science. “We want to understand in detail how the energy from super-massive black holes influences the formation and evolution of their host galaxies.” Continue reading Recording the impact of a super-massive black hole
Far outback in Western Australia, at the Murchison Radio Astronomy Observatory located on Boolardy Station, 315 km north-east of Geraldton, 32 tiles each carrying 16 dipole antennas have begun to collect scientific data on the Sun. At the same time they are providing engineering information to be used to extend the facility to a much bigger array of 512 tiles – the Murchison Widefield Array (MWA).

Western Australia’s International Centre for Radio Astronomy Research (ICRAR) is only three months old but is rapidly expanding—much like the early Universe. ICRAR’s scientists have ambitious projects ahead contributing to global science and engineering through the SKA.
Imagine a telescope so revolutionary that in one week it will gather more information than that contained in all the words spoken in human history.
The Square Kilometre Array, or SKA, will be the world’s most powerful radio telescope and will dramatically increase mankind’s understanding of the universe.

CSIRO’s Dr John O’Sullivan, winner of the 2009 Prime Minister’s Prize for Science, is now working on the next generation of radio telescopes.
John’s latest efforts are directed towards the development of an innovative radio camera or ‘phased array feed’ with a uniquely wide field-of-view for the Australian SKA Pathfinder (ASKAP) radio telescope.
