An international consortium behind a plan to build the world's most powerful radio telescope has signalled further delays in deciding where it should go.
Australia and New Zealand, in a joint bid, are vying with South Africa for the project, known as the Square Kilometre Array.
An announcement had been expected this week .
Instead, the consortium has agreed to set up a working group to further examine further the two bids for $2 billion project.
It's due to report back next month.
The SKA will be 50 to 100 times more sensitive than today's most powerful radio telescopes.
Scientists hope it will shed new light on fundamental questions about the universe, including how it began and why it is expanding.
