Astronomers Witness Longest-Lasting Gamma-Ray Burst in History, 8 Billion Light-Years Away
A gamma-ray burst lasting over seven hours was recorded 8 billion light-years away, revealing a rare type of cosmic explosion and challenging current astrophysics models.

JWST Detects Oldest Supernova Ever Seen, Linked to GRB 250314A
Astronomers using the James Webb Space Telescope have detected the oldest supernova ever recorded, tied to gamma-ray burst GRB 250314A. Occurring when the universe was only 730 million years old, the explosion provides a rare glimpse into the first generations of stars and early galaxy growth, highlighting Webb’s unmatched ability to study the di...

Astronomers Spot the Longest Gamma-Ray Burst Ever Seen: What You Need to Know
A powerful gamma-ray burst detected in July 2025 has stunned astronomers by lasting nearly seven hours, making it the longest GRB ever recorded. Named GRB 250702B, the event produced repeated pulses and unusual afterglows, raising theories about rare “middleweight” black holes tearing apart stars in deep space.

NASA Launches Rescue Mission to Save the Swift Gamma-Ray Burst Observatory
NASA is preparing an unprecedented mission to save the Neil Gehrels Swift Observatory, a key gamma-ray burst monitor launched in 2004 but now rapidly losing altitude. Partnering with Katalyst Space Technologies, NASA will send a robotic servicer on a Pegasus XL rocket to rendezvous with Swift, inspect it, and raise it to a stable orbit. The effort ...

NASA Detects Strange Gamma-Ray Burst That Defies 50 Years of Expectations
Astronomers have spotted GRB 250702B, a gamma-ray burst that erupted several times over two days—something never seen before. Detected by NASA’s Fermi and China’s Einstein Probe, the event defies current models of collapsing stars or black holes, hinting at an entirely new cosmic phenomenon.

Brightest Gamma-Ray Burst Ever Observed Reveals Cosmic Secrets
On October 9, 2022, astronomers detected GRB 221009A, the most powerful gamma-ray burst ever recorded, earning the nickname “BOAT” (Brightest Of All Time). This rare, once-in-10,000-year event came from a galaxy 2 billion light-years away and temporarily blinded gamma-ray detectors. It revealed new insights into stellar death, as the associated...

New Study Finds Hercules-Corona Borealis Great Wall Bigger and Nearer Than Thought
GRBs uncover a more massive and closer Hercules–Corona Borealis Great Wall, reshaping cosmic scale theories.Astronomers have found that the Hercules–Corona Borealis Great Wall—the largest known structure in the universe—is even larger and closer than previously thought. Spanning 10 billion light-years, this immense cluster of galaxies was t...

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.
