Using gravitational waves to hunt for dark matter
Using computer simulations, an international team of cosmologists have discovered that observations of gravitational waves from merging black holes may unveil the true nature of dark matter. Their findings are presented at the 2023 National Astronomy...

Black hole ripples could help pin down expansion of Universe
The echoes of light from jets launched from black holes offers a new way to pin down the distance to these exotic objects and to study a largely unobserved population in the centre of the Galaxy. It could also even help determine the rate of...

PIGS find ancient stars in the heart of the Milky Way
An international team of researchers has obtained the largest set of detailed observations yet of the oldest stars in the centre of our Galaxy, the Milky Way. The Pristine Inner Galaxy Survey (PIGS) team finds that this group of stars is slowly...
Four panels showing the stages of gravitational interactions between two black holes.
Quasar discs could host black hole collision events
New research, in the wake of the gravitational wave discoveries, sheds light on the environments that could lead to black hole merger events. The work is presented this week at the 2023 National Astronomy Meeting by PhD student at the University of...

Getting a foot on the cosmic age ladder: using machine learning to estimate stellar ages
Researchers from Keele University have developed a machine learning technique that helps astronomers better estimate the ages of stars from the chemicals within their atmospheres. The new research will be presented at the 2023 National Astronomy...
The artist's impression shows a star being consumed by a black hole. The black hole appears red and black and glows with a red light. The star in the foreground is orange in colour and also glows.
Astronomers witness energetic switch on of black hole
A team of astronomers led by researchers from the University of Birmingham, University College London and Queen’s University Belfast have discovered one of the most dramatic 'switches on' of a black hole ever seen. They will present their findings on...
Time to act on light pollution, say leading experts at NAM conference
Action on light pollution is long overdue, campaigners will say at a panel event today (3 July) at the National Astronomy Meeting in Cardiff. The panellists call for UK governments and local authorities to put policies in place to restore our view of...

Solar astronomers discover ‘shooting stars’ on the Sun’s corona
A team of astronomers from several European institutions led by Northumbria University in Newcastle has discovered ‘shooting stars’ on the Sun. Observations from the European Space Agency’s Solar Orbiter (SolO) have revealed never-before-seen...

‘Sandwich’ discovery offers new explanation for planet formation
Scientists have made a new discovery on how small planets might form. Researchers at the University of Warwick investigated the ‘birth environment’ of planets – areas of gas and dust that swirl around a central star – known as the protoplanetary disc...
