Astronomers Decode Mysterious Blast From Space That Lasted Seven Hours
The signal lasted for seven hours, and its duration and intensity suggest previously unknown processes in the universe.

JWST Spots Most Distant Supernova Ever, From 730 Million Years After Big Bang
Scientists have confirmed the most distant supernova ever observed, exploding just 730 million years after the Big Bang. Detected through a powerful gamma-ray burst and later verified by the James Webb Space Telescope, the event offers a rare glimpse of the deaths of the universe’s first stars during the era of reionisation and challenges expecta...

Fermi Telescope Detects Gamma-Ray Halo That Could Be First Direct Dark Matter Signal
NASA’s Fermi Gamma-ray Space Telescope has detected a faint halo of high-energy gamma rays around the Milky Way’s centre—matching predictions for dark-matter annihilation. The finding, reported by Professor Tomonori Totani, could represent the first direct glimpse of dark matter, but scientists caution that alternative explanations remain and...

Scientists Recreate Cosmic ‘Fireballs’ in Lab to Solve Mystery of Missing Gamma Rays
Scientists recreated cosmic plasma beams at CERN to study why certain gamma rays vanish in space. The results showed the beams remain stable, suggesting ancient intergalactic magnetic fields, not beam collapse, hide the signals. The discovery provides new insight into cosmic jets and the universe’s earliest magnetic traces.

Astronomers Predict 90 Percent Chance of Spotting an Exploding Black Hole in Next Decade
Astronomers now predict a 90% chance of detecting an exploding primordial black hole within a decade. Such an event would confirm Stephen Hawking’s theory that black holes evaporate, releasing a flash of radiation and exotic particles. Detecting one would revolutionize physics and rewrite our understanding of the universe.

New Study Confirms TeV Halos Are Common in Middle-Aged Pulsars
A recent study by researchers from the U.S. and Mexico using data from the HAWC Observatory has confirmed that TeV halos are a universal feature of middle-aged pulsars. These extended regions of gamma-ray emission are significantly larger than pulsar wind nebulae and may help identify otherwise undetectable pulsars. The findings challenge existing ...

The Universe’s Brightest Lights Have Surprisingly Dark and Mysterious Origins
NASA’s Fermi Gamma-ray Space Telescope has revealed that some of the universe’s brightest light sources originate near supermassive black holes in galaxy centres. These active galactic nuclei emit intense radiation, including gamma rays and X-rays, despite black holes themselves being invisible. Their powerful jets and high-energy emissions cha...

Thunderstorms May Skew Ultra-High-Energy Gamma Ray Measurements, Experts Warn
The detection of ultra-high-energy gamma rays by the Large High Altitude Air Shower Observatory (LHAASO) in Tibet has sparked debate over the accuracy of the findings. Experts suggest that thunderstorms could interfere with measurements by amplifying particle showers in the atmosphere, leading to overestimated gamma ray energy levels. A study by As...

A Nearby Supernova May End Dark Matter Search, Claims New Study
A supernova within the Milky Way could revolutionise dark matter research by producing gamma rays from axions, elusive particles theorised to exist during a star's core collapse. Scientists at UC Berkeley are calling for gamma-ray telescopes to monitor the sky, ensuring readiness for the next nearby supernova. Such an event could confirm the axion'...

NASA's ER-2 Aircraft Unveils Complex Gamma Rays from Thunderstorms
Recent flights by NASA’s ER-2 aircraft have uncovered new types of gamma rays generated by thunderstorms. These observations indicate that gamma-ray glows are more common and long-lasting than previously thought, while newly identified flickering gamma-ray flashes might provide insights into the mechanisms behind lightning formation.

NASA Detects Most Powerful Gamma-Ray Bursts Close To Earth
The signal originated from the direction of the constellation Sagitta, and travelled an estimated 1.9 billion years to reach Earth, NASA said.

Study Explains Blinking Gamma-Ray Bursts Using Falling Stardust, Unsteady Jets
Astrophysicists have developed the first 3D simulation of the entire evolution of a jet from its birth by a rotating black hole to its emission far from the collapsing star. Simulation explains that as the star collapses, its material falls on the disk that swirls around the black hole. This falling material tilts the disk, and, in turn, tilts the ...

Spectacular Gamma Radiation From Collapse Of Dying Star Could Change Understanding Of The Universe
Scientists have recorded a cosmic explosion of gamma radiation from a collapsing star that challenges the established theory of gamma-ray bursts. The scientists said that these explosions occur when a massive star abruptly detonates and turns into a black hole.

Astronomers Observe Most Distant Explosion in Universe That Took Place 10 Billion Years Ago
Astronomers have spotted one of the most powerful and oldest explosions that took place nearly 10 billion years ago. The explosion that has been named SGRB181123B occurred just 3.8 billion years after the Big Bang.
