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 ...

Rochester Institute of Technology researchers played a significant role in an international announcement today that has changed the future of astrophysics. The breakthrough discovery of colliding ...

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

The final stage of a superkilonova. Astronomers may have discovered a never-before-seen cosmic explosion that effectively combines a supernova with a kilonova—the blast that results when two dead, ...

Neutron stars explained through stellar remnants and collapsed stars, revealing extreme density, gravity, magnetism, and ...

A strange double flash in a distant galaxy may be the first glimpse of a “superkilonova,” a cosmic one‑two punch that fuses two of the most violent stellar deaths known. Astronomers watched a massive ...

Researchers have spent 10 years improving the massive detectors they use to catch shockwaves from colliding black holes, and now the science is... On Sept. 14, 2015, physicists attained the ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into ...

Talk about a heavy snack. For the first time, astronomers have witnessed a black hole swallowing a neutron star, the most dense object in the universe — all in a split-second gulp. Ten days later they ...

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 ...
