A view of the Southern African Large Telescope.

SALT’s excellence and achievements recognised by DST

The Southern African Large Telescope (SALT) welcomes the 2016 Science Diplomacy Award given by the Department of Science and Technology as a result of the telescope consistently contributing to globally significant discoveries in astronomy. Science diplomacy is the use of scientific collaborations among nations to address common problems and build constructive international partnerships. The Science […]


A major supercluster of galaxies uncovered

SALT helps international team to discover major supercluster of galaxies hidden by Milky Way Observations done with the Southern African Large Telescope (SALT) helped a team of South African and international collaborators to uncover a previously unknown, major supercluster in the constellation Vela. The Vela supercluster might have a significant influence on the motion of […]


Lodén 1 debunked

SALT helps proving the putative old and nearby cluster Lodén 1 to be neither old, nor nearby, nor a cluster. Stellar clusters are the keys to study stellar evolution and structure. By characterizing stellar clusters, we understand how the age, mass, and metallicity affect the formation and evolution of stars. For instance, stellar clusters with similar […]


Laser Frequency Comb testing

SALT tests a high accuracy and high precision calibration ruler for its High Resolution Spectrograph Since last week, the Southern African Large Telescope (SALT) in Sutherland has been testing a Laser Frequency Comb, which is a calibration device that uses powerful lasers and photonic crystal fibres to produce the equivalent of a ruler that is […]


Echoes of ancient exploding star

SALT helps to pinpoint echoes of an ancient exploding star on our stellar doorstep When amateur astronomers found a peculiar looking nebula (called Te 11) in the Orion constellation in 2010, astronomers weren’t quite sure what to make of it. It could have been the envelope of an old star like the Sun or the […]


Record-breaking cosmic blast

Southern African Large Telescope helps to unveil a record-breaking cosmic blast! A collaboration of telescopes, including a major contribution by the Southern African Large Telescope in Sutherland, has unveiled a cosmic explosion about 200 times more powerful than a typical supernova, events which already rank amongst the mightiest outbursts in the universe. It was more […]


Too large a black hole

Southern African Large Telescope reveals too large a black hole The Southern African Large Telescope (SALT), Africa’s most powerful eye on the sky, has been used to discover a supermassive black hole in the centre of a modest galaxy, SAGE0536AGN. All but the smallest galaxies are thought to harbour a black hole, but in this […]


SALT Conference 2015

The SALT Science Conference 2015 The Southern African Large Telescope (SALT) Foundation and South African Astronomical Observatory (SAAO) are delighted with the success of the SALT Science Conference 2015 held in Stellenbosch from the 1st to the 5th June. The programme was jam-packed with talks, poster presentations, practical workshops and discussions showcasing SALT’s capabilities. Over […]


A Close Shave

A Neighbourhood Star’s Close Shave With Our Solar System Astronomers identify the closest known flyby of a star other than the Sun to Earth. The star likely passed through the Oort Cloud of comets at the edge of our solar system 70,000 years ago. Astronomers from the South African Astronomical Observatory (SAAO) and Southern African […]


Luminous Blue Variable

Discovery of a New “Luminous Blue Variable” Star Astronomers identify an extremely rare star which could soon die in a spectacular supernova explosion. Astronomer Dr A. Kniazev from the South African Astronomical Observatory (SAAO), together with collaborators from the Lomonosov Moscow State University Dr. V. Gvaramadze and Dr. L. Berdnikov have recently discovered a new […]
