Stars often die with a final burst of beauty. For the first time, astronomers have captured visual proof that a star can explode not once, but twice before fading forever. Using the European Southern ...

Nuclear weapons tests are among the most violent events humans can trigger, and that violence leaves fingerprints in the ...

Astronomers have, for the first time, witnessed a star meeting a dramatic end by exploding twice. In a study published in Nature Astronomy, researchers analyzed the centuries-old remains of supernova ...

Type Ia supernovae are critical tools in astronomy, since they all appear to explode with the same intensity, allowing us to use their brightness as a measure of distance. The distance measures ...

For the first time, astronomers have obtained visual evidence that a star met its end by detonating twice. By studying the centuries-old remains of supernova SNR 0509-67.5 with the European Southern ...

Detonation combustion achieves near-constant-volume burning, drastically reducing entropy generation and wasting less energy as heat compared to traditional deflagration propulsion. Its supersonic ...

Detonation loading in cylindrical structures is a complex phenomenon that involves the rapid exposure of components to high-pressure shock waves generated by explosive events. This process not only ...

WASHINGTON (Reuters) -Astronomers have spotted two hefty white dwarf stars - highly compact stellar embers - orbiting close together that appear destined to die in an extraordinarily violent quadruple ...
