The South African Large Telescope (SALT) has been hailed as the largest optical telescope in the Southern hemisphere and is equal to the largest telescope in the world.
SALT is based in the South African Astronomical Observatory in Sutherland, in the Northern Cape, the observatory is the darkest in the world, and thus makes looking into galaxies easier.
Some of the discoveries made through SALT include the revelation of a super-massive black hole in the centre of a modest galaxy.
The galaxy was only found by accident in the distant background of a survey which meant that a nearby dwarf galaxy needed to be studied.
South Africa owns 33% of the observatory but it is a collaborative project with other countries such as the US. Each country gets allocated time according to the percentage they own.
