UP part of global research team to present the first image of Sagittarius A*
Astronomers have unveiled the first image of the supermassive black hole at the centre of our own Milky Way galaxy. The announcement was made at simultaneous press conferences around the world. Professor Roger Deane, an Extraordinary Professor at the University of Pretoria and Director for the Centre of Astrophysics at the University of Witwatersrand and Wits Postdoctoral Fellow, Dr Iniyan Natarajan, were part of this global collaboration with the Event Horizon Telescope team. They are the only two African-based representatives who are part of the global team of more than 300 astronomers.

More than 300 researchers and 80 institutions, including the University of Pretoria have collaborated with the Event Horizon Telescope to bring us the first image of Sagittarius A. Learn more about what it took to do this in this infographic
Watch as this video sequence zooms into the black hole (Sgr A*) at the centre of our galaxy. Beginning with a broad view of the Milky Way, we dive into the dense clouds of gas and dust at our galactic centre. The stars here have been observed with ESO’s Very Large Telescope and ESO’s Very Large Telescope Interferometer for decades, the black hole’s immense gravitational pull distorting...
This is the first image of Sagittarius A* (or Sgr A* for short), the supermassive black hole at the centre of our galaxy. It’s the first direct visual evidence of the presence of this black hole. It was captured by the Event Horizon Telescope (EHT), an array which linked together eight existing radio observatories across the planet to form a single “Earth-sized” virtual telescope. The...
Researchers at the University of Pretoria are determining the threat posed to the ecosystem and that of human health as people expand their settlements closer to the natural habitats of bats. It is vital that bats are well protected. Ultimately, if bat populations decrease, humans will be affected.
