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.

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 Explores Industry Collaboration to Boost Swift Observatory’s Orbit and Extend Its Mission
NASA is partnering with U.S. firms to study boosting the Neil Gehrels Swift Observatory’s orbit, aiming to extend its scientific life and advance orbital servicing technologies. Funded through Phase III SBIR awards, the project explores cost-effective solutions while preserving Swift’s astrophysics role. Collaboration with Starfish Space may al...

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...

Unprecedented Cosmic Explosion Discovered: Could This Be The Greatest Space Mystery Ever?
A newly detected cosmic explosion, EP240408a, could be the result of a white dwarf's death, creating a high-speed jet. It offers new insights into astrophysics.

Could a Supernova Threaten Earth’s Survival? Here's What You Need to Know
Supernova explosions have the potential to harm Earth’s atmosphere, particularly the ozone layer. However, no stars close enough to cause damage are currently identified. The risks are low, but gamma-ray bursts, caused by neutron star mergers, may pose an even greater threat in the future.

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.

Indian Astronomers On Team Which Spotted Shortest Gamma-Ray Bursts From Dying Star
A group of astronomers, including from India, has detected a very short, powerful burst of high-energy radiation that lasted for about a second and had been racing towards the earth for nearly half the present age of the universe.

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).
