Starlink satellites emit bright, unintended and unexpected signals that can be detected by radio telescopes.
New ASKAP images reveal a giant hydrogen ring around the spiral galaxy NGC 4632.
Astronomers have detected a long-running source of slow, repeating radio pulses that can’t be explained by current theories – but it’s probably not aliens.
Astronomers have detected the coldest star ever found to emit radio waves using the Australian SKA Pathfinder telescope.
Astronomers have for the first time detected the background hum of gravitational waves likely caused by merging black holes.
The darkness of the night sky seems so obvious as to need no explanation – yet it has intrigued and baffled scientists for centuries.
Our Sun will likely go out quietly – but not all such stars do. A new radio detection of a supernova can help us better understand these cosmic cataclysms.
The accumulated radio emission from mobile phones on Earth is beginning to become quite significant.
Magnetic fields billions of light years away offer clues to the nature of intense flashes from the sky known as fast radio bursts.
The current race to the Moon is opening up opportunities for lunar astronomy.
Machine learning is becoming an indispensable tool in astronomy by sorting through enormous datasets from telescopes.
Astronomers have long known where water is first formed in the universe and how it ends up on planets, asteroids and comets. A recent discovery has finally answered what happens in between.
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.
Astronomers have detected a radio glow caused by shockwaves in the gigantic filaments between galaxy clusters in the ‘cosmic web’ which pervades the Universe.
Can artificial intelligence transform the search for alien intelligence?
AI’s ability to identify ‘technosignatures’ missed by classical algorithms is an exciting step forward for radio astronomers.
Hundreds of thousands of antennas across the Western Australian outback will transform our view of the Universe.
The stars, planets and Milky Way we see at night are part of a wilderness shared across the globe and across centuries. But does BlueWalker 3 herald a night sky polluted with bright satellites?
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.
