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 resear…
Multicoloured filaments in space surrounding a bright blue core, Sagittarius A*. The filaments appear to be red, and green, and look gaseous.
Black hole at centre of Milky Way unpredictable and chaotic
An international team of researchers, led by postgraduate student Alexis Andrés, has found that the black hole at the centre of our galaxy, Sagittarius A*, not only flares irregularly from day to day but also in the long term. The team analysed 15 ye…

Gaia finds fossil spiral arms in Milky Way
An international team of astronomers, led by researcher Chervin Laporte of the Institute of Cosmos Sciences of the University of Barcelona (ICCUB-IEEC), has used data from the Gaia space mission to create a new map of the Milky Way’s outer disc. Intr…
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 pr…

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 Astronom…
RAS launches new multi-disciplinary journal
The Royal Astronomical Society is pleased to announce the launch of its first new journal in almost 100 years. Tentatively titled RAS Techniques and Instruments, it will cover topics in astronomy and geophysics ranging from instrumentation, data scie…

Planetary Shields Will Buckle Under Stellar Winds From Their Dying Stars
Any life identified on planets orbiting white dwarf stars almost certainly evolved after the star’s death, says a new study led by the University of Warwick that reveals the consequences of the intense and furious stellar winds that will batter a pla…

Kepler telescope glimpses population of free-floating planets
Tantalising evidence has been uncovered for a mysterious population of “free-floating” planets, planets that may be alone in deep space, unbound to any host star. The results include four new discoveries that are consistent with planets of similar ma…

New observations of the most distant galaxies close in on cosmic dawn
New observations of six of the most distant galaxies currently known have helped to pinpoint the moment of first light in the Universe, known as ‘cosmic dawn’. The new work is published in Monthly Notices of the Royal Astronomical Society, and puts…
