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 -- ...

Astronomers still don’t know where gamma ray bursts come from, but NASA researchers have concluded that they may originate from at least two different types of cosmic explosions. Dr. Jay Norris of ...

Gamma-ray bursts (GRBs) are the brightest explosions in the universe. In just a few seconds, they can outshine all the stars in their host galaxy combined, releasing more energy than our sun will emit ...

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 Northwestern-led team of astronomers reached for the stars with a recently compiled gamma-ray galaxy database. The public database, known as BRIGHT, or the Broad-band Repository for Investigating ...

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 ...

LOS ALAMOS, N.M., Dec. 7, 2022—The standard view of gamma-ray bursts as a signature for different types of dying stars might need a rewrite. Recent astronomical observations, supported by theoretical ...

Rings of dust that evidence the BOAT, as seen by the XMM-Newton Observatory. Image: ESA/XMM-Newton/M. Rigoselli (INAF) The gamma-ray burst, affectionately dubbed ‘BOAT’ (Brightest of All Time), has ...

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 ...

LAS VEGAS – December 7, 2022 – The mysteries of the cosmos continue to amaze astronomers, and with each new observation comes a chance to deepen – or upend – our understanding of the universe. In the ...
