After six decades during which it tracked lunar missions, spotted distant pulsars and quasars, and even expanded our concept of the size of the Universe, the Parkes telescope is still going strong.
Astronomers hunting extraterrestrials were excited to discover an intriguing signal, but closer inspection has revealed it wasn’t aliens.
Fluctuating radio waves that appear to come from near the heart of the Milky Way are a new puzzle for astronomers.
Technology is allowing astronomers to study and analyse galaxies in far more detail than was previously possible.
Australia’s ASKAP radio telescope probes the Universe more deeply than ever before, revealing unseen features of the cosmos.
The pandemic has underscored that the world requires agility for survival. That makes blue skies science, which encourages curiosity and nimble thinking, perhaps more important than ever.
No conclusive evidence that extraterrestrial life exists has been found…yet.
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.
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.
One way forward would be to abandon the traditional approach of using single-dish telescopes for SETI.
Visitors are discouraged from the remote desert location where powerful telescopes are listening to the universe.
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 astronomers started using the new ASKAP radio telescope, they discovered mysterious circular blobs of unknown size and distance in the sky.
Radio telescopes are incredibly sensitive to phone network interference.
The discovery of phosphine in the acidic clouds of Venus can’t be explained by any known chemical or geological processes.
An upgrade for the Australia Telescope Compact Array will enable major new discoveries about the universe
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.
Radio flare may be the result of a giant star orbiting some unusual object – a combination we have never seen before.
