‘Swallowed’, torn up or live on: How Earth will fare when the Sun dies
Our solar system and everything within it - including the Earth - will look very different when the Sun dies. But whether the planet we call home is “swallowed” up by our dying star or manages to escape its clutches, only time will tell. The inner...

Trailblazing seismologist named new editor-in-chief of GJI
A globally-renowned seismologist who has studied every major earthquake of the past 35 years has been appointed editor-in-chief of Geophysical Journal International (GJI), one of the world's leading peer-reviewed research journals in solid-Earth...

End of nuclear secrecy? Underground tests now '99% detectable'
Secret underground nuclear tests could now be a thing of the past thanks to a major scientific breakthrough in ways to identify them. A team of Earth scientists and statisticians say they can now tell with 99 per cent accuracy if such an explosion...
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...

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...

Evidence of the amino acid tryptophan found in space
Using data from the Spitzer space observatory, Dr Susana Iglesias-Groth , a researcher from The Instituto de Astrofísica de Canarias (IAC), has found evidence for the existence of the amino acid tryptophan in the interstellar material in a nearby...
