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...

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 ...

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.

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.

Scientists Apply Stephen Hawking's Theory to Propose Detectable ‘Black Hole Morsels’ in Space
A new study suggests “black hole morsels” — tiny, asteroid-sized black holes from cosmic mergers — could emit detectable bursts of Hawking radiation. Observatories like HESS, HAWC, and Fermi may already hold clues. Detecting them could unlock insights into quantum gravity, unknown particles, and even hidden dimensions beyond the Standard Mo...

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...
