The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, ...

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 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 ...

When the remnants of two stars collide, their union can launch a dazzling jet of high energy matter. A new computer simulation reveals how the merger, which forms a black hole, emits that bright beam, ...

An artist's illustration depicts how a rupture in the crust of a highly magnetized neutron star can trigger high-energy eruptions. - S. Wiessinger/NASA Goddard Space Flight Center Astronomers have ...

New research suggests that colliding neutron stars can briefly "trap" ghostly particles called neutrinos, which could reveal new secrets about some of space's most extreme events. When it comes to ...

"For the first time, we see the creation of atoms; we can measure the temperature of the matter and see the microphysics in this remote explosion." When you purchase through links on our site, we may ...

Neutron stars are extreme stellar objects. With magnetic fields billions of times more intense than Earth's and density second only to black holes, these dead stars push the bounds of physical laws we ...

Although the first detection of gravitational waves in 2015 gets a lot of press, the detection of GW170817—the first binary neutron star collision—confirms how important gravitational waves likely are ...

The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, Swift Observatory and other telescopes. A kilonova is a "the afterglow ...
