The collision and merger of two neutron stars—the incredibly dense remnants of collapsed stars—are some of the most energetic events in the universe, producing a variety of signals that can be ...

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

In a remarkable cosmic event, astronomers have detected a black hole-star merger that has resulted in the longest gamma-ray burst ever recorded. This event not only shatters previous records in ...

The celestial remnant that lingers after two neutron stars merge isn't like either of its parents. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works ...

False color plot showing the density of the mass in the equatorial (bottom) and meridional, or “southern” (top) planes of a neutron star merger remnant about 100 milliseconds after the merger. In the ...

When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were witnessing something special. The cosmic flash GRB 250702B was no ...

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 ...

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 ...
