We don’t know what the black hole at the centre of the Milky Way will look like.
The first ever picture of the Milky Way's black hole is expected to be a bright crescent shape rather than a disk.
Very few African universities offer postgraduate degrees in astronomy. This gap in knowledge and training can be addressed through international partnerships and collaboration.
The GLEAM view of the centre of the Milky Way, in radio colour. Red indicates the lowest frequencies, green indicates the middle frequencies and blue the highest frequencies. Each dot is a galaxy, with around 300,000 radio galaxies observed as part of the GLEAM survey.

To the naked eye the universe we can see on a clear night is dotted with thousands of stars. See through radio eyes, then things look very different.
Jets generated by supermassive black holes at the centers of galaxies can transport huge amounts of energy across great distances.

It's difficult to get jets - powerful, lightning fast particles - to give up their secrets. The new Square Kilometre Array radio telescope could hold the key to solving jets' mysteries.
Light from the universe’s first galaxies destroyed the hydrogen atoms that formed during the Big Bang.

A new telescope aims to figure out what became of the universe's original atoms once the first stars began to shine.

What's particularly exciting about "first light" images from South Africa's MeerKAT radio telescope is that they prove Africa is a rising star in the world of astronomy.
The FAST telescope.
The Aperture Spherical Radio Telescope could help reveal how the universe evolved.
The new discovery: The C-shaped “wide angle tail galaxy” (pink) surrounded by the galaxies of the Matorny-Terentev cluster (white).
The find by citizen scientists of at least 40 galaxies in a cluster more than a billion light years away is the astronomical equivalent of finding a needle in a haystack.
The Mopra radio telescope faces closure.
When government funding is cut from science and research in Australia, there are other ways to try to draw money from the public's purse?

Cleo Loi was an undergraduate when she made a startling discovery. Her story shows how brilliance, dedication and imagination drive science.

Telescopes have come a long way since the days when they were all about lone astronomers watching the night sky through their upstairs windows. Today teams of astrophysicists build and use much more modern…
