The temperature of elementary particles has been observed in the radioactive glow following the collision of two neutron stars and the birth of a black hole. This has, for the first time, made it ...

Neutron stars are the densely compact cores remaining as one possible result of a supernova. These star remnants are ...

Sparse halos of neutrinos within the hearts of exploding stars exert a previously unrecognized influence on the physics of the explosion and may alter which elements can be forged by these violent ...

Astronomers have discovered the first radio signals from a unique category of dying stars, called Type Ibn supernovae, and these signals offer new insights into how massive stars meet their demise.

Some of the most spectacular images ever captured by the Hubble Space Telescope reveal the violent remains of exploding stars. These supernova remnants include glowing clouds of gas, rapidly expanding ...

In 1987, earthbound observers saw a star explode in the nearby dwarf galaxy called the Large Magellanic Cloud. Astronomers eagerly studied this supernova–the closest seen in the past 300 years–and ...
