Physicists to Listen Closely to Black Holes Ring
Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet Earth rolls around the sun like a marble tossed into a funnel (Earth does not fall into the sun due to the Earth's sideways momentum).

Study doubles the number of known repeating fast radio bursts
Statistics tools support the idea that all radio bursts may repeat if observed long enough. Fast radio bursts (FRBs) are repeating flashes of radio waves that remain a source of mystery to astronomers. We do know a few things about them: FRBs originate from far outside the Milky Way, for instance, and they're probably produced from the cinders of dying stars.

Experts confirm meteorite find in Elmshorn
Sky rock testifies to intense collisions in early solar system A suspected meteorite find at the end of April in Elmshorn in Schleswig-Holstein has now been confirmed: Scientists from Münster and Dresden have analyzed the find and determined that the rock is a so-called common type H chondrite. This is a group of meteorites that have a particularly high proportion of metal.

University of Glasgow researchers prepare for next gravitational wave observing run
Researchers from the University of Glasgow's School of Physics & Astronomy are preparing for the next observing run of the international LIGO-Virgo-KAGRA (LVK) network of gravitational-wave detectors. The LVK collaboration consists of scientists across the globe who use a network of observatories-LIGO in the United States, Virgo in Europe, and KAGRA in Japan-to search for gravitational waves, or ripples in space-time, generated by colliding black holes and other extreme cosmic events.

Explosion in the Night Sky - First Brightness Measurements of Supernova SN2023ixf
Astronomers at the University of Potsdam have succeeded in making one of the world's first brightness measurements of the supernova SN2023ixf in the constellation Ursa Major, which was discovered only on Friday evening. It is the brightest detected outburst in more than ten years in the galaxy Messier 101.

NASA Scientists Make First Observation of a Polar Cyclone on Uranus
Scientists used ground-based telescopes to get unprecedented views, thanks to the giant planet's position in its long orbit around the Sun. For the first time, NASA scientists have strong evidence of a polar cyclone on Uranus. By examining radio waves emitted from the ice giant, they detected the phenomenon at the planet's north pole.

NASA’s Perseverance Rover Captures View of Mars’ Belva Crater
The six-wheeled scientist encountered the crater during its latest science campaign in search of rock samples that could be brought to Earth for deeper investigation. The Mastcam-Z instrument aboard NASA's Perseverance Mars rover recently collected 152 images while looking deep into Belva Crater, a large impact crater within the far larger Jezero Crater.

First radio detection of Type Ia supernova explosion captured by e-MERLIN telescope at Jodrell Bank
After decades of trying, astronomers have found the origin of a Type Ia supernova explosion using radio emissions, thanks to the e-MERLIN telescope network based at Jodrell Bank , The University of Manchester. A supernova is a powerful and luminous explosion and is the end of a star's life. In the case of Type 1a supernovae, they can be used to measure distances in the Universe or for the study of dark energy.

Curved spacetime in a quantum simulator
New techniques can answer questions that were previously inaccessible experimentally - including questions about the relationship between quantum mechanics and relativity. The theory of relativity works well when you want to explain cosmic-scale phenomena - such as the gravitational waves created when black holes collide.

Found: a likely volcano-covered terrestrial world outside the Solar System
Astronomers from Université de Montréal have discovered an Earth-sized exoplanet around a nearby small red dwarf star that appears to be carpeted with volcanoes. Björn Benneke, a Professor at the Université de Montréal and member of the Trottier Institute for Research on Exoplanets, whose team led this discovery.

JUICE magnetometer passes fitness tests and is ready to take data
The magnetometer instrument on the JUpiter ICy moons Explorer (JUICE) spacecraft has been rigorously tested and is ready to fulfil its mission. The magnetometer instrument (J-MAG), led by Imperial College London researchers, consists of three sensors, all of which were shown to be operating well. The deployment also marks the first time a quantum interference sensor - a precise but delicate technology - has been used beyond Earth orbit.

Martian crust like heavy armour
A strong quake in the last year of the NASA Mars InSight mission, enabled researchers at ETH Zurich to determine the global thickness and density of the planet's crust. On average, the Martian crust much thicker than the Earth's or the Moon's crust and the planet's main source of heat is radioactive.

Shining ring around black holes recreated in the lab
Researchers have created a spinning disc of plasma in a lab, mimicking discs found around black holes and forming stars. The experiment more accurately models what happens in these plasma discs, which could help researchers discover how black holes grow and how collapsing matter forms stars. As matter approaches black holes it heats up, becoming plasma - a fourth state of matter consisting of charged ions and free electrons.

Largest cosmic explosion ever seen
A team of astronomers led by the University of Southampton have uncovered the largest cosmic explosion ever witnessed. The explosion is more than ten times brighter than any known supernova (exploding star) and three times brighter than the brightest tidal disruption event, where a star falls into a supermassive black hole.

Celestial monsters at the origin of globular clusters
Researchers have found strong evidence that supermassive stars can explain the anomalies observed in large clusters of stars. Globular clusters are the most massive and oldest star clusters in the Universe. They can contain up to 1 million of them. The chemical composition of these stars, born at the same time, shows anomalies that are not found in any other population of stars.

James Webb Space Telescope reveals composition of protoplanetary disc
  Young stars are surrounded by discs of material from which future planets form. The James Webb Space Telescope has revealed the chemical composition of the disc around the star J160532, which turns out to be rich in hydrocarbons. In recent years, observations  have shown that rocky exoplanets are very abundant around low-mass stars such as J160532.

Young stars are surrounded by disks of material where future planets are born. The James Webb telescope has revealed the chemical composition of the disk of the star J160532, rich in hydrocarbons. Observations in recent years have shown that rocky exoplanets are very abundant around "light" stars like J160532.

NASA’s Webb Takes Closest Look Yet at Mysterious Planet
A science team gains new insight into the atmosphere of a "mini-Neptune," a class of planet common in the galaxy but about which little is known. NASA's James Webb Space Telescope has observed a distant planet outside our solar system - and unlike anything in it - to reveal what is likely a highly reflective world with a steamy atmosphere.

Researchers measure the light emitted by a sub-Neptune planet’s atmosphere for the first time
For more than a decade, astronomers have been trying to get a closer look at GJ 1214b, an exoplanet 40 light-years away from Earth. Their biggest obstacle is a thick layer of haze that blankets the planet, shielding it from the probing eyes of space telescopes and stymying efforts to study its atmosphere.
