Call for Editor-in-Chief of GJI
Could you be the next Editor-in-Chief (EiC) of Geophysical Journal International (GJI)? If you are highly motivated, with an expertise in solid-Earth geophysics, an interest in academic journal publishing and a vision for the future of GJI, this coul…
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 A…
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 Swinb…
An image of the star-forming region IC348 overlaid with an image of the tryptophan molecule.
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 star…
An artist's concept of the Kepler Space Telescope in space. The telescope is roughly cylindrical in shape, made of rust and silver coloured materials. Many stars can be seen in the background, as well as the Sun and Earth-Moon system.
Astronomers discover last planets seen by Kepler Space Telescope
Astronomers at the Massachusetts Institute of Technology and the University of Wisconsin at Madison, with the help of citizen scientists, have discovered the last three planets that the Kepler Space Telescope gazed upon before going dark. The researc…
This artist's impression of a quasar shows a bright orange and white disc of material centred around a small black circle. A jet of light emanates from this circle, white and blue in colour.
An X-ray look at the heart of powerful quasars
Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history, known as SMSS J114447.77-430859.3, or J1144 for short. The new perspective sheds light on the inner workings of quasars and h…
An artist's impression of a black hole accretion shows a large yellow disc shaped formation with a small black circle at the centre. The disc appears to be sucking in blue light that emanates from a blue sphere in the bottom left corner of the image.
Astronomers reveal the largest cosmic explosion ever seen
A team of astronomers led by researchers at the University of Southampton has uncovered the largest cosmic explosion ever witnessed. The explosion is more than ten times brighter than any known supernova. The research is published in Monthly Notices…
An artist's impression of a disc shaped cloud of dust around a black hole. Two jets coming from either side of the disc appear bright blue and extend towards the outside of the image.
Hidden supermassive black holes brought to life by galaxies on collision course
Astronomers have found that supermassive black holes obscured by dust are more likely to grow and release tremendous amounts of energy when they are inside galaxies that are expected to collide with a neighbouring galaxy. The new work, led by researc…
An image of the Milky Way warped around a small black circle at the centre of the image.
Light-bending gravity reveals one of the biggest black holes ever found
A team of astronomers have discovered one of the biggest black holes ever found, taking advantage of a phenomenon called gravitational lensing. The findings are published in Monthly Notices of the Royal Astronomical Society. The team, led by Durham…
The artist's impression shows a large, grey rocky body in outer space with a bright yellow-white star in the background. Faint stars are also seen in the background.
Redness of Neptunian asteroids sheds light on early Solar System
Asteroids sharing their orbits with the planet Neptune have been observed to exist in a broad spectrum of red colour, implying the existence of two populations of asteroids in the region, according to a new study by an international team of research…
The artist's impression shows a source of bright yellow-white light against the dark backdrop of space. Coming from the centre of the light source is a conical jet that is blue in colour. Faint, smaller galaxies are seen in the background of the image,
Galaxy changes classification as jet changes direction
A team of international astronomers have discovered a galaxy that has changed classification due to unique activity within its core. The galaxy, named PBC J2333.9-2343, was previously classified as a radio galaxy, but the new research has revealed ot…

Royal Astronomical Society announces all journals to publish as open access from 2024
The Royal Astronomical Society (RAS) has today announced that all journals published by the Society will be Open Access (OA) from January 2024. This move will enable everyone in the global community to have free, immediate, and unrestricted access to…
