Deputy President of the Republic of South Africa, Mr David Mabuza, today officially inaugurated the MeerKAT radio telescope. After a decade in design and construction, this project of South Africa's Department of Science and Technology has now begun science operations. At the launch event, a panorama obtained with the new telescope was unveiled that reveals extraordinary detail in the region surrounding the supermassive black hole at the centre of our Milky Way Galaxy. This is one of several very exciting new views of the Universe already observed by the telescope.
"We wanted to show the science capabilities of this new instrument", says Fernando Camilo, chief scientist of the South African Radio Astronomy Observatory (SARAO), which built and operates MeerKAT in the semi-arid Karoo region of the Northern Cape. "The centre of the galaxy was an obvious target: unique, visually striking and full of unexplained phenomena – but also notoriously hard to image using radio telescopes", according to Camilo. The centre of the Milky Way, 25,000 light-years away from Earth and lying behind the constellation Sagittarius (the "Teapot"), is forever enshrouded by intervening clouds of gas and dust, making it invisible from Earth using ordinary telescopes. However, infrared, X-ray, and in particular, radio wavelengths penetrate the obscuring dust and open a window into this distinctive region with its unique 4 million solar mass black hole. "Although it's early days with MeerKAT, and a lot remains to be optimised, we decided to go for it – and were stunned by the results."
