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.

Galactic Gamma-Ray Source Map Reveals Birthplaces of High-Energy Particles: Study
A total of nine sources of extremely high-energy gamma rays have been identified in a new catalogue compiled by researchers.

Gamma Ray Emission, Trillion Times More Energetic Than Light, Observed
In a cosmic first, researchers have observed the most powerful and luminous yet known energy release -- a trillion times more energetic than visible light -- in the brightest type of electromagnetic events known to occur in the universe called gamma-ray bursts (GRBs).

NASA Names New Gamma-Ray Constellations After Hulk, Godzilla
NASA has used certain characters from modern myths such as the "Hulk" and "Godzilla" to name its new set of 21 gamma-ray constellations constructed in celebration of its Fermi Gamma-ray Space Telescope's 10th year of operations.

Scientists Detect Gravitational Waves From A New Kind Of Nova, Sparking A New Era In Astronomy
Some 130 million years ago, in a galaxy far away, the smoldering cores of two collapsed stars smashed into each other. The resulting explosion sent a burst of gamma rays streaming through space and rippled the very fabric of the universe.
