Research findings are available online in the journal Nature Communications. The original story " Scientists find evidence of a rare double supernova in the Jellyfish Nebula " is published in The ...

In 2015, astrophysicists discovered a system consisting of two compact stars orbiting each other: a pulsar (i.e., a highly magnetized rapidly rotating, light-emitting neutron star) and a so-called ...

An international team of astronomers have created the longest consistent 3D model of a neutrino-driven supernova explosion to date, helping scientists to better understand the violent deaths of ...

Researchers have found white dwarf stars with masses close to the maximum stable mass (called the Chandrasekhar mass) are likely to produce large amounts of manganese, iron, and nickel after it orbits ...

Astronomers are now in a better position to interpret observations of supernova remnants thanks to computer simulations of these cataclysmic events by RIKEN astrophysicists. When certain types of ...

When massive stars die, they explode, leaving behind supernova remnants. Given how common binary star systems are - more than ...

Researchers leverage a multiangle simulations approach to elucidate the roles of neutrino fast flavor conversion affects core-collapse supernova explosions. (Nanowerk News) Core-collapse supernovae ...

When some stars die, they do not do so alone, potentially solving a long-standing mystery around a particular class of cosmic explosion called an interacting supernova.

Simulation of a Type Ia supernova in which material ejected from the explosion (red) runs into a companion star (blue). This collision adds extra ultraviolet light to the supernova as viewed from ...

Type Ia supernovas are astronomers’ best tools for measuring cosmic distances. In a first, researchers have managed to re-create one on a supercomputer, giving a boost to a leading hypothesis for how ...
