Hunga Volcano special issue of GJI: connection between atmosphere and Earth
A paper accepted for the special issue of Geophysical Journal International (GJI) on the 2022 January 15 eruption of the Hunga Tonga-Hunga Ha’apai volcano examines the connection between the atmosphere and the solid Earth highlighted by this event...
The SDV tide gauge at Macau. A wall with very obvious water markings. Behind the wall are several buildings. Water beneath the wall and markings is dark and still.
Hunga Volcano special issue of GJI: analysis of tsunamis in Lingding Bay
The 2022 January 15 eruption of the Hunga volcano in Tonga caused tsunamis worldwide. A paper by Wang et al in the special issue of Geophysical Journal International (GJI) on the 2022 Hunga eruption highlights how atmospheric pressure waves created...
A composite image made of two images. The image on the left is a 3D model of the Cat's Eye Nebula, a nebula made of tendrils of blue and light orange hued gas. The image on the left is an image of the Cat's Eye Nebula in 2D, imaged by the Hubble Space Telescope.
Cat’s Eye Nebula seen in 3D
Researchers have created the first computer-generated three-dimensional model of the Cat's Eye Nebula, revealing a pair of symmetric rings encircling the nebula’s outer shell. The rings’ symmetry suggests they were formed by a precessing jet...
Images showing the simulation - 3 different figures depict glowing pink and purple tendrils against the black background of space. In the third, 2 yellow-white orbs are labelled 'MW' for Milky Way and M31.
Scientists unveil most accurate virtual representation of the Universe
Scientists have produced the largest and most accurate virtual representation of the Universe to date. An international team of researchers, led by the University of Helsinki, and including members from Durham University in the UK, used supercomputer...
An illustration of a blue-white hued star in space surrounded by rings of orange and brown coloured planetary material. A small planet, blue in colour, lies just off the centre of the image.
Planetary bodies observed in habitable zone of dead star
A ring of planetary debris studded with moon-sized structures has been observed orbiting close to a white dwarf star, hinting at a nearby planet in the “habitable zone” where water and thus life could exist, according to a new study led by UCL...
A diffuse galaxy in green and blue hues. White and orange stars appear around the clouds of the galaxy.
Evidence emerges for dark-matter free galaxies
An international team of astronomers led by researchers from the Netherlands has found no trace of dark matter in the galaxy AGC 114905, despite taking detailed measurements over a course of fourty hours with state-of-the-art telescopes. They will...
A bright white galaxy that is round in shape, glowing against the darkness of space.
The last breaths of massive galaxies
A team of astronomers propose a scenario in which galaxies with active cores may undergo a period of rapid star birth before shutting down completely. The research, conducted by astronomers from the University of Southampton, the Institute of...

Magnetic fields implicated in the mysterious midlife crisis of stars
Middle-aged stars can experience their own kind of midlife crisis, experiencing dramatic breaks in their activity and rotation rates at about the same age as our Sun, according to new research published today in Monthly Notices of the Royal...

Meet the Martian meteorite hunters
A team at the Natural History Museum (NHM), London is paving the way for future rovers to search for meteorites on Mars. The scientists are using the NHM’s extensive meteorite collection to test the spectral instruments destined for the ExoMars rover...

Martian global dust storm ended winter early in the south
A dust storm that engulfed the entire Red Planet in 2018 destroyed a vortex of cold air around the Martian south pole and brought an early spring to the hemisphere. By contrast, the storm caused only minor distortions to the polar vortex in the...

Unravelling the knotty problem of the Sun’s activity
A new approach to analysing the development of magnetic tangles on the Sun has led to a breakthrough in a longstanding debate about how solar energy is injected into the solar atmosphere before being released into space, causing space weather events...

Supermassive black holes put a brake on stellar births
Black holes with masses equivalent to millions of suns do put a brake on the birth of new stars, say astronomers. Using machine learning and three state of the art simulations to back up results from a large sky survey, the researchers resolve a 20...
