A powerful "gamma-ray burst" has been seen exploding from merging neutron stars hidden within a previously unknown ...

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

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

Astronomers trace the Small Magellanic Cloud’s unusual stellar motions to a past cosmic encounter.

The Small Magellanic Cloud (SMC), one of the Milky Way's closest galactic neighbors, is undergoing a transformation visible from the southern hemisphere. This change is due ...

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 ...

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 ...

(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 ...

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 ...

Researchers said this event, called GRB 230906A, is likely in a stream of gas located about 4.7 billion light-years from ...

Scientists observe a dramatic collision between two planets, offering insights into the formation of Earth's Moon 4.5 billion years ago.
