Neutrinos are some of nature’s most elusive particles, but new research has used them to create an image of our own galaxy.
The planet Halla looks like it should have been devoured by its host star, a red giant called Baekdu – but a secret in the star’s past may hold the answer to the planet’s present.
Radiation from the brightest cosmic explosion ever seen may have been mixing with gas and dust around its dying star – making the signal last longer.
One of the few examples of a fast radio burst and the slow-moving, star forming gas in its origin galaxy has been linked together – thanks to observations from a CSIRO telescope.
Upgrades to the hardware and software of the advanced observatory should allow astrophysicists to detect much fainter gravitational waves than before.
Stars begin to expand when they run out of fuel and can become thousands of times larger, consuming any planets in the way. For the first time, astronomers have witnessed one such event.
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.
Beyond just looking at black holes, the next-generation Event Horizon Telescope collaboration is the first to bring together perspectives from across the sciences and humanities.
Some physicists think we live in a multiverse, surrounded by universes not quite like our own. What does that mean for life?
The discovery of massive, early galaxies could force scientists to rethink how the first galaxies formed after the Big Bang.
Astronomers have found that mysterious dark energy may originate in black holes.
Black holes can have a mass equivalent to that of millions of suns. Other, smaller, black holes can combine the mass of Mount Everest into the size of an atom.
While we can’t see inside a black hole, we can spot the intensely bright glowing disc that surrounds one. Now, we might better understand why these discs appear to ‘twinkle’.
Can artificial intelligence transform the search for alien intelligence?
To understand this question, we need to travel back in time.
Gamma-ray bursts occur when a massive star explodes or when two neutron stars merge. A newly discovered burst has puzzled astronomers, as it lasted much longer than astronomers would have expected.
It has been one year since the launch of the James Webb Space Telescope and six months since the first pictures were released. Astronomers are already learning unexpected things about the early universe.
A new particle accelerator has just begun operation. It is the most powerful accelerator of its kind on Earth and will allow physicists to study some of the rarest matter in the universe.
