The Southern African Large Telescope (SALT) has placed South Africa and the continent on the global science map, but there have also been collateral benefits.
The tiny town of Sutherland had been stagnant in terms of socio-economic development before the construction of SALT, explained Sivuyile Manxoyi, from the South African Aomy Observatory (SAAO). Following the construction of the telescope, the town had gone from having two bed-and-breakfast establishments to having more than 40 options for accommodation.
Manxoyi was speaking at the five-day SALT conference, taking place at Stellenbosch University until 5 June. The event was opened by Science and Technology Minister Naledi Pandor.
“Sutherland has become a tourist destination, something that would have been unheard of before SALT,” Manxoyi said. “Now, between 10 000 and 12 000 tourists visit the area every year.”
More importantly, SALT had presented an ideal opportunity to promote aomy, mathematics, physical science and chemistry as subjects for study and career options. Manxoyi said the SAAO was providing guidance to teachers all over the country on the teaching of aomy and building enthusiasm for mathematics and science.
The observatory was also interacting with thousands of pupils, taking them to observatories and involving them in science clubs and star-gazing events. Through creating awareness about aomy, the future of the impoverished region would be vastly improved.
Speaking earlier at the conference, Pandor said aomical sciences were an important facet of South Africa’s strategy for research, development and innovation, and that aomy partnerships presented unique and invaluable opportunities. “Such partnerships build infrastructure for aomy and for wider use.
“Big telescopes require high-speed research networks and computing resources, which, in turn, enable our life and climate scientists to share and analyse huge data sets – a precondition for the development of new drugs and vaccines – as well as effectively combating and adapting to climate change.”
Aomy partnerships had also helped to popularise the study of aomy in Africa and further afield. “As a result of the various human capital development programmes associated with Africa’s SKA [Square Kilometre Array] initiatives, new aomy programmes have been established at several African universities, including in Kenya, Madagascar and Mozambique,” the minister said.
“Under other programmes, several postgraduate students from Africa are studying at European universities, contributing to Europe’s knowledge generation, while leading European and American aomers have taken up positions in Africa, for example through the South African Research Chairs Initiative.”
She said aomy was expanding Africa’s future workforce of scientists and engineers. “South Africa pursued the SKA project by using the lessons learned from SALT as the basis for our planning and partnerships. The links we developed through the SALT project allowed us to build on existing networks and partnerships to secure the iconic SKA, an extremely important strategic initiative that puts science and technology to work for the benefit of all Africans.”
SALT has been available to scientists since 2012. By the end of April this year, it had produced 109 papers based on SALT observations. The paper on the discovery of the first-known stars in the Milky Way galaxy was published in the prestigious Nature journal. These stars are situated on the far side of the galaxy, 80 000 light years from Earth.
“Our aim is to position Africa as a global centre of research excellence for multiwavelength aomy, with optical, radio and gamma-ray telescopes working together to achieve common scientific goals,” Pandor said.
“We need to do more to build bridges across the multiwavelength spectrum, but it is encouraging to see positive developments in this regard, for example, the MeerLICHT, a partnership between the South African, Dutch and British aomy communities.”
MeerLICHT aims to provide a real-time optical view of the radio-transient sky. It will receive its input from the MeerKAT operators in Cape Town so that simultaneous optical and radio data can be obtained.
