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 ...

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 ...

Caltech astronomer Mansi Kasliwal and her colleagues were not expecting to chase a mystery that blurred the line between a supernova and a kilonova. Yet that is where the evidence has led after an ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, Swift ...

For the first time, astronomers are studying the aftermath of a kilonova — an epic burst of energy that occurs when two neutron stars collide and merge. NASA has used it Chandra X-ray Observatory to ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. When two neutron stars sidle up to each other, sparks are bound to ...

These images taken by NASA’s Hubble Space Telescope reveal a new type of stellar explosion produced by the merger of two compact objects: either two neutron stars or a neutron star and a black hole.

If two dense neutron stars collided relatively close to Earth, the resulting kilonova would shine day and night with the brightness of the moon squeezed into a small dot. “At night, it would be by far ...
