Australian astronomers are part of a prize-winning team that was the first to pinpoint the location of a fast radio burst. But there is much we still don't know about these mysterious bursts.
The two giant radio galaxies found with the MeerKAT telescope. In the background is the sky as seen in optical light. Overlaid in red is the radio light from the enormous radio galaxies, as seen by MeerKAT.

Based on what we currently know about the density of giant radio galaxies in the sky, the probability of finding two of them in this region is extremely small.
A collaboration between Australian and German scientists gives an unrivalled view of the structure of the Universe.

We observed a powerful flare and a huge burst of radio waves from our nearest stellar neighbour, Proxima Centauri, indicating violent space weather around the star.
When the USSR launched the world's first satellite, Sputnik 1 didn't do much other than regularly "beep" over the radio. Yet, this simple sound is associated with the beginnings of space exploration.
Astronomers think they've identified which galaxy was the source of a blast radio energy, over in a fraction of a second. And it's much closer to us than the others detected, so far.

Astronomers found something not predicted by current theory when they took a closer look at the emissions from a neutron star with a very strong magnetic field.

Astronomers are getting ready to say good bye to the radio emission from a neutron star merger – one of the most energetic events in the universe – that was detected last year.
The Vela pulsar makes about 11 complete rotations every second, it also has a glitch.
