Many telescopes use the radio spectrum to learn about the cosmos. Just as human development leads to more light pollution, increasing numbers of satellites are leading to more radio interference.
Our galaxy should be full of traces of dead stars. Until now, we have found surprisingly few of these supernova remnants, but a new telescope collaboration is changing that.
The technology of an advanced alien civilization is likely to produce many signs that could be detected across the vastness of space. Two astronomers explain the search for technosignatures.
Astronomers studying fast radio bursts recently discovered one that repeats, has a persistent radio signal and originated in a galaxy much closer than it should have.
Fanaroff is one of the key individuals responsible for the current growth and strength of astronomy in South Africa.
Organic human-level intelligence may be just a brief interlude in human history before the machines take over.
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.
Visitors are discouraged from the remote desert location where powerful telescopes are listening to the universe.
The collapse of the Arecibo Observatory in Puerto Rico was a result of financial neglect – and was a long time coming.
The Arecibo radio telescope has collapsed but its amazing discoveries will live on.
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.
