Research Highlights

Artist impressions of a so-called 'Old Smoker' red giant star and 'Squalling Newborn' protostar, both observed as part of new research.
'Old smokers' and 'squalling newborns' among hidden stars spotted for first time
'Hidden' stars including a new type of elderly giant nicknamed an 'old smoker' have been spotted for the first time by astronomers. The mystery objects exist at the heart of our Milky Way galaxy and can sit quietly for decades – fading almost to...
Early images of Uranus and Neptune compared to those reprocessed in a new study.
New images reveal what Neptune and Uranus really look like
Neptune is fondly known for being a rich blue and Uranus green – but a new study has revealed that the two ice giants are actually far closer in colour than typically thought. The correct shades of the planets have been confirmed with the help of...
Dynamic spectra (or “waterfall” plots) for all the bursts from FRB 20220912A.
Never-before-seen Fast Radio Burst sheds new light on deep space signals
Astronomers are continuing to unravel the mystery of deep space signals after discovering a never-before-seen quirk in a newly-detected Fast Radio Burst (FRB). FRBs are millisecond-long, extremely bright flashes of radio light that generally come...

Solar activity likely to peak next year, new study suggests
Researchers at the Center of Excellence in Space Sciences India at IISER Kolkata have discovered a new relationship between the Sun’s magnetic field and its sunspot cycle, that can help predict when the peak in solar activity will occur. Their work...

Using eclipses to calculate the transparency of Saturn’s rings
A Lancaster University PhD student has measured the optical depth of Saturn’s rings using a new method based on how much sunlight reached the Cassini spacecraft while it was in the shadow of the rings. The optical depth is connected to the...
Background image of simulation of present-day matter from FLAMINGO simulation, with three insets showing detail.
Astronomers carry out largest ever cosmological computer simulation
An international team of astronomers has carried out what is believed to be the largest ever cosmological computer simulation, tracking not only dark but also ordinary matter (such as planets, stars and galaxies), giving us a glimpse into how our...
An artist's impression of a T Tauri star. The star appears in colours of red, purple, orange and yellow, and is obscured by dust clouds.
First observational evidence of gamma-ray emission in young Sun-like stars
A team of scientists from Argentina and Spain have reported the first observational evidence that a type of young low-mass star, known as T Tauri stars, are capable of emitting gamma radiation. The study is published in Monthly Notices of the Royal...
An image of two merging galaxies. Both are light blue and cream in colour. Faint stars are seen in the background.
Galaxy mergers shed light on galactic evolution model
An Australian astronomer has solved a century-old mystery regarding how galaxies evolve from one type to another. The same study shows that the Milky Way, the galaxy we live in, was not always a spiral. The work by Professor Alister Graham from...
An image showing two black wholes interacting in space - two black circles surrounded by stars and nebulae appear warped.
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...
