Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.

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 ...

The violent collision of two neutron stars is providing new insights on how the universe’s heaviest elements were created.

A powerful "gamma-ray burst" has been seen exploding from merging neutron stars hidden within a previously unknown mini-galaxy leftover from an ancient cosmic crash. The "collision within a collision" ...

GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...

Some of the most spectacular images ever captured by the Hubble Space Telescope reveal the violent remains of exploding stars. These supernova remnants include glowing clouds of gas, rapidly expanding ...

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 ...

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 ...

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 ...
