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…

New RAS journal invites submissions and reviewers
The new open access RAS journal, RAS Techniques and Instruments (RASTI), is set to open for submissions in November 2021, and invites the astronomy and geoscience communities to make submissions from next month.  RAS Techniques and In…
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…
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…
Earth-like biospheres on other planets may be rare
A new analysis of known exoplanets has revealed that Earth-like conditions on potentially habitable planets may be much rarer than previously thought. The work focuses on the conditions required for oxygen-based photosynthesis to develop on a planet,…
Mysterious hydrogen-free supernova sheds light on stars’ violent death throes
A curiously yellow pre-supernova star has caused astrophysicists to re-evaluate what’s possible at the deaths of our Universe’s most massive stars. The team describe the peculiar star and its resulting supernova in a new study published today in Mon…
Satellites contribute significant light pollution to night skies
Scientists reported new research results today suggesting that artificial objects in orbit around the Earth are brightening night skies on our planet significantly more than previously understood. The research, accepted for publication in Monthly…
New study suggests supermassive black holes could form from dark matter
A new theoretical study has proposed a novel mechanism for the creation of supermassive black holes from dark matter. The international team find that rather than the conventional formation scenarios involving ‘normal’ matter, supermassive black hole…
