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 ...

Using NASA’s Chandra X-ray Observatory and other telescopes, astronomers have traced a short-duration gamma-ray burst event called GRB 230906A to a faint dwarf galaxy embedded in a vast stream of ...

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 ...

(THE CONVERSATION) 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 ...

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 ...

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 ...

Astronomers have detected a neutron star collision in an unexpected place, deep within a tiny, faint galaxy. Located about 4.7 billion light-years away, this collision occurred within a vast gas ...

In a patch of sky about 1.2 billion light-years from Earth, astronomers have found a cosmic rarity: three galaxies caught in a merger, and all three of their central supermassive black holes are ...
