Second only to black holes, neutron stars—incredibly dense star remnants—are the densest objects in the universe. When ...

In August 2017, astronomers witnessed an incredible explosion in space — two ultra-dense neutron stars collided head-on, releasing an extraordinarily powerful jet of radiation. Two days later, the ...

Most elements lighter than iron are forged in the cores of stars. A star’s white-hot center fuels the fusion of protons, squeezing them together to build progressively heavier elements. But beyond ...

Explore the cosmic aftermath of a neutron star collision. This animation breaks down the detection of a kilonova and explains ...

Using the James Webb Space Telescope (JWST), astronomers have traced an incredibly bright gamma-ray burst (GRB) back to its source, a violent collision between two neutron stars. The ring on your ...

Neutron star mergers are a treasure trove for new physics signals, with implications for determining the true nature of dark matter, according to physicists. Neutron star mergers are a treasure trove ...

"These extreme events stretch the bounds of our understanding of physics, and studying them allows us to learn new things." When you purchase through links on our site, we may earn an affiliate ...

Scientists at Goethe University Frankfurt have identified a new way to probe the interior of neutron stars using gravitational waves from their collisions. By analyzing the "long ringdown" phase—a ...

The cosmic origins of elements heavier than iron are mysterious. One elemental birthplace came to light in 2017 when two neutron-rich dead stars collided and spewed out gold, platinum and other hefty ...
