World's most powerful radio telescope to be shared by 3 nations 
May 25, 2012 | 10:18 am 



REPORTING FROM JOHANNESBURG, South Africa -- South African politicians and 
scientists were jubilant Friday after a decision was announced to locate the 
Square Kilometer Array (SKA) radio telescope in South Africa, Australia and New 
Zealand.

But their joy was tinged with disappointment that South Africa's bid for the 
entire project did not succeed. The decision was nonetheless seen as a major 
boost for South African science.

"The SKA will transform our view of the universe; with it we will see back to 
the moments after the Big Bang and discover previously unexplored parts of the 
cosmos.” said Dr. Michiel van Haarlem, interim director general of the SKA 
Organization, in a statement after the announcement of the decision in 
Amsterdam.

The $2-billion project will involve several thousand high-, mid- and 
low-frequency receiving dishes set over a huge geographical area in remote 
areas where there is little interference from mobile phone, radio, television 
and other signals. Combining all the signals from the SKA will form the 
equivalent of a radio telescope with a one-square kilometer dish, and will be 
50 times more sensitive than any in existence, according to the SKA 
Organization.

The likelihood of the sites remaining quiet radio zones in the future was a key 
factor in their choice. The South African location is in the Karoo, in the 
country's southwest. But dishes will be located across southern Africa and as 
far north as Ghana. The Australian location is a remote area of Western 
Australia with dishes to be located in other parts of the continent and in New 
Zealand.

According to the SKA Organization, astronomers will be able to glimpse the 
formation and evolution of the first stars, and investigate the nature of 
gravity and whether there is life beyond Earth.

South African media had earlier been confident the entire project, which will 
be the world's most powerful radio telescope, would go to South Africa.

South African Minister for Science and Technology Naledi Pandor said Friday the 
decision to split the project was unexpected. She said experts on the SKA 
advisory committee had agreed Africa was the best site.

"We had hoped the unambiguous recommendation of the [advisory committee] would 
be accepted as the most sound scientific outcome," Pandor said in a statement 
Friday. "We accept the compromise in the interest of science and as 
acknowledgement of the sterling work done by our scientists and the excellent 
SKA project team."

The organization is a global science and engineering project including Britain, 
South Africa, Australia, New Zealand, China, Canada, the Netherlands and Italy, 
with India an associate member.
