Researchers have spotted millions of galaxies in the most detailed radio survey of the southern sky ever conducted. It has smashed previous records for survey speed.
Radio telescopes are incredibly sensitive to phone network interference.
Like a cosmic butterfly in the sky, radio galaxy PKS 2014-55 was observed by CSIRO researchers with the Australian SKA Pathfinder telescope.
This observation means astronomers can now develop and test theories that explain how high-mass stars gain their mass.
The Dish in Parkes is scanning the southern Milky Way, searching for alien signals.

Today we hear about the Parkes radio telescope's role in the search for alien life. Our guide is the irrepressible John Sarkissian, the scientist who's had his eye on The Dish since childhood.
‘The size, the grandeur, the peacefulness of being in the dark’: what it’s like to study space at Siding Spring Observatory.

Three hours north-east of Parkes lies a remote astronomical research facility, unpolluted by city lights, where researchers are trying to unlock some of the biggest questions about our Universe.
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.
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.
By sharing a location with the SKA, HIRAX will be able to conduct science in “radio-clear” skies across its wide frequency range.
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.
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.
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.
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.
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.
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 Aperture Spherical Radio Telescope could help reveal how the universe evolved.
