A fleet of NASA space telescopes has traced a brief flash of gamma rays to a likely collision between two neutron stars, placing the violent event inside a tiny, gas-shrouded galaxy that had escaped ...

Most gamma-ray bursts—the brightest, most powerful explosions in the universe—are tracked back to the deaths of massive stars. But a new discovery suggests that such enormous explosions can come from ...

Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an ...

Astronomers have spotted a jaw-dropping collision between two neutron stars – and it may have produced gold and platinum. The discovery in a tiny far-away galaxy is the first time this has been seen ...

It turns out that looming collision between our Milky Way and Andromeda galaxies might not happen after all. Astronomers reported Monday that the probability of the two spiral galaxies colliding is ...

Add Yahoo as a preferred source to see more of our stories on Google. A hypothetical view from Earth as the Andromeda galaxy (on left) is about to collide with part of the Milky Way galaxy. Our Milky ...
