A recent Physical Review Letters study presents a new model for quark star merger ejecta that could resolve whether these cosmic collisions generate ordinary matter or something different. Subscribe ...

Physicists provide a viable and testable explanation for how UHECRs are created. Ultrahigh Energy Cosmic Rays are the highest-energy particles in the universe, whose energies are more than a million ...

Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for a process that had previously only been theorised. The study provides new ...

A strange, ultra-bright flash in a distant galaxy has given astronomers their strongest hint yet that a new class of stellar ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...

In an ejection that would have caused its rotation to slow, a magnetar is depicted losing material into space in this artist’s concept. The magnetar’s strong, twisted magnetic field lines (shown in ...

Scientists have discovered a new way to probe the interiors of neutron stars by using gravitational waves to turn them into "cosmic tuning forks." The reverberations of such ripples in spacetime could ...

A massive star may have burst, leaving behind two dense, dead cores, which then collided and caused another explosion ...

The discovery of a metal-rich star packed with both light and heavy elements hints at exotic stellar explosions and the role of ancient dwarf galaxies in seeding the cosmos with uranium and thorium.
