Astronomers have revisited data from a dramatic collision of neutron stars to help resolve the infamous ‘Hubble tension’.
Listen to the The Conversation’s Curious Kids podcast to hear astronomer Michael Lam on what theories scientists have for what came before the Big Bang.
The best map yet of cosmic magnetic fields has been created with Australia’s most powerful radio telescope.
Seeing a signal in different kinds of light is like having a text written in several forms of writing – it makes it easier to decipher.
The black holes could be relics from a time before the Big Bang.
Ground stations in Australia are crucial for contacting the astronauts travelling to the Moon.
With college students less likely to read through a full textbook than they once were, video games can help keep them engaged.
South Africa is using homegrown technology to answer questions about where our universe came from and where it is going.
While direct evidence of multiple universes is hard to come by, indirect evidence raises intriguing possibilities.
The Rubin Observatory in Chile has the largest camera ever built – and is set to find objects never before seen by human eyes.
The electron is the tiniest particle. Then there are neutrinos, which are as small but may weigh more.
Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields from the Big Bang may offer a solution.
Radio pulses repeating every minute-to-hour have puzzled astronomers, but a new paper in Nature Astronomy might finally shed some light.
Fire obviously isn’t a liquid or a solid. In fact, it’s not matter at all – it’s a process.
Unlike some other over-hyped meteor showers, this one is the real deal.
Most of the universe is made up of dark matter and dark energy. The majority of everything else is dispersed throughout space as tiny particles.
Will the universe keep existing forever? An astrophysicist explains how scientists aren’t entirely sure, but they can make predictions.
The true “informational age” of the cosmos may be 62 billion years, not just the 13.8 billion years of our current expansion.
Physicists often say space-time “exists,” but what does that really mean? A hidden confusion between happening and being could be warping our view of reality.
