Welcome to SKA


Australia and New Zealand SKA project

The Square Kilometre Array, or SKA, is a global next-generation radio telescope project involving institutions from over 20 countries. The SKA will be the largest and most capable radio telescope ever constructed. During its 50+ year lifetime, it will expand our understanding of the universe and drive technological development worldwide. Australia and southern Africa will each host different SKA components.

I am pleased to begin this update with very exciting recent news out of the world of low-frequency radio astronomy. Regular readers of Nature (or a multitude of news outlets and social media accounts) will have seen that the signature of the first stars that formed after the big bang was detected using the EDGES instrument at the Murchison Radio-astronomy Observatory (MRO). Congratulations to Judd Bowman’s team for completing what I understand was a highly complex survey conducted over many years. Read more..

Detection of earliest stars bodes well for SKA

1 March 2018

EDGES.pngA US-based team led by Dr Judd Bowman has detected the first stars to form after the big bang using a small telescope at the CSIRO-managed Murchison Radioastronomy Observatory (MRO). The discovery was made using the EDGES telescope to sort through radio signals from across the Universe, to pin-point a tiny, faint signal from 13.8 billion years ago. It’s being heralded as a triumph of precision engineering by a top astronomy team.

The discovery has big implications for the SKA which will enjoy the same radio-quiet conditions that made this discovery possible. Dr Robert Braun, Science Director at the SKA Organisation explains:

“This is a powerful demonstration of what can be achieved with the combination of an excellent site and world-class engineering, boding well for the great discoveries that will be enabled by the SKA,” said Dr Braun.

“While the EDGES team have made a detection of the ‘global signature’, that is averaged over the sky, of the Cosmic Dawn, the SKA will allow very precise measurements to be made of the structures within the Universe during this crucial, early heating phase. It may even be possible for the SKA to form the first direct images of these structures; pointing to the locations of the very first stars and galaxies to have formed.”

First SKA dish antenna unveiled

6 February 2018


The first fully assembled SKA dish was unveiled at a ceremony in China on 6 Feb 2018. The prototype antenna will soon be tested in South Africa where hundreds of dishes will eventually form the SKA-Mid array. The dish was developed in China as part of a consortium of international partners including institutions from Australia.

The fully assembled prototype is a major milestone for the SKA as we build towards the beginning of construction in 2019. The dish is one of two SKA antennas at the prototype testing phase, with SKA low frequency antennas currently being tested at Australia’s SKA site in Western Australia.
