"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 ...

A supercomputer simulation of a mere 10 milliseconds in the collapse of a massive star into a neutron star proves that these catastrophic events, often called hypernovae, can generate the enormous ...

A long-duration gamma-ray burst observed in late 2021 revealed signatures typically associated with short-duration bursts, forcing puzzled scientists to create a new model for the origin of this ...

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 ...

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 ...
