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 ...

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, ...

When it comes to "busting" cosmic ghosts, only the most extreme objects in the universe may be up to the task: neutron stars. Scientists have performed simulations of collisions between these ...

"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 ...

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 ...

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 ...

Astronomers have used a range of telescopes, including Hubble, to watch as particles dance around a neutron star collision that created the smallest black hole ever seen. When you purchase through ...
