The first direct visual evidence of the supermassive black hole in the centre of galaxy Messier 87 and its shadow.
Astronomers say they have "seen what we thought was unseeable" in releasing the first image of a supermassive black hole. So how did we get to this historic observation?

Perhaps precisely because they are so elusive, Fast Radio Bursts have received a lot of attention in the years since their discovery.
Central antennas of the Australia Square Kilometre Array Pathfinder.
We still don't know what causes these mysterious Fast Radio Bursts deep in the universe, but we've detected a whole new batch of them.
HIRAX prototype dishes at Hartebeesthoek Astronomy Observatory near Johannesburg.
By sharing a location with the SKA, HIRAX will be able to conduct science in “radio-clear” skies across its wide frequency range.
An image by MeerKAT shows hydrogen gas in M83, a famous spiral galaxy.
A precursor to the Square Kilometre Array- the MeerKAT telescope - is being built right now and remarkable progress has been made in the last 12 months.

All it took was a single email alert to send the world's astronomers searching for the source of the latest gravitational wave detected.
The refurbished radio telescope in Kutunse, Ghana paves the way for astronomy in Africa.
Astronomy on the continent has been given a much needed boost with Ghana's converted radio telescope between it and South Africa, to conduct scientific observations.
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…
