Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe's most energetic and mysterious light shows -- ...

BEIJING, Feb. 20 (Xinhua) -- Chinese researchers have developed a novel model to explain the origin of an ultra-long gamma-ray burst (GRB), challenging the conventional understanding of these violent ...

A peculiar cosmic explosion first detected by NASA’s Swift observatory on Christmas Day 2010 was caused either by a novel type of supernova located billions of light-years away or an unusual collision ...

Scientists from the RIKEN Cluster for Pioneering Research and collaborators have used simulations to show that the photons emitted by long gamma-ray bursts–one of the most energetic events to take ...

A strange gamma-ray explosion that fired off repeated bursts from the same patch of sky over roughly seven hours has now been traced to its likely cause: a black hole ripping apart a star that strayed ...

Astronomers spend careers watching stars collapse and explode, but an eruption spotted in July pushed beyond anything seen before. The event, called GRB 250702B, released high-energy radiation for ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film version of ...

When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were witnessing something special. The cosmic flash GRB 250702B was no ...

A snapshot from a simulation showing how the merger of a black hole and a neutron star can generate powerful jets and winds that produce gamma-ray bursts. A new study presents a framework linking the ...
