Kilonova? More like killer-nova. Violent star collisions, called a kilonova, could devastate our planet due to a lethal spew of radiation — namely gamma rays, cosmic rays and x-rays — that are emitted ...

Being too close to two neutron stars colliding spectacularly may be catastrophic for a planet like Earth, scientists have calculated. This type of cosmic event is known as a kilonova and releases huge ...

You’ve probably heard of a supernova, when a star reaches the end of its life and explodes in a huge burst of energy. But these aren’t the only dramatic explosions out in space — there are also ...

In the second-brightest supernova ever seen, two neutron stars have collided and created a variety of rare heavy elements, many of which are needed for life on Earth. The extraordinarily bright ...
