Wolf-Rayet 104's Orbit Tilt Reduces Gamma-Ray Burst Threat, Study Finds
New research using Keck Observatory’s instruments confirms that the orbit of Wolf-Rayet 104 is tilted 30-40 degrees away from Earth, lowering concerns about a possible gamma-ray burst. Previously, it was believed that the system’s alignment could pose a risk. However, spectroscopy data now challenges these assumptions, raising new questions abo...

ISRO's Space Telescope Spots Over 600 Gamma-Ray Bursts Over 8 Years
India's AstroSat space telescope has achieved a significant milestone by detecting more than 600 Gamma-Ray Burst (GRB), each marking the death of a massive star or merging of neutron stars.

Largest Cosmic Explosion Ever, Raging For 3 Years, Spotted By Astronomers
Last year, astronomers witnessed the brightest explosion on record - a gamma-ray burst known as GRB 221009A.

Neutron Star Collision Captured in Millimetre Light for the First Time
Researchers have found a way to capture millimetre-wavelength light originating from a collision of a neutron star with another star. The flash emerging from this collision was among the most energetic short-duration gamma-ray bursts (GRBs) ever observed, according to the researchers.

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 ...

Cosmic Explosions Even More Powerful Than First Thought: Study
The biggest explosions since the Big Bang set the universe in motion some 13 billion years ago produced even more energy than first thought, scientists said Wednesday.

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).

Research Reveals Universe's Most Powerful Explosions
Gamma-ray bursts (GRBs) in the universe are rare explosions that happen when extremely massive stars go supernova. A study provides an inside look at the most powerful explosions in the universe.
