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

The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors—a small, gas-rich galaxy visible to the ...

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

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" ...

The Hubble Space Telescope observed the debris belt and dust clouds around the star Fomalhaut, which was blotted out to allow the fainter features around it to be seen. - NASA / ESA / Paul Kalas / ...

Astronomers have detected a neutron star collision in an unexpected place, deep within a tiny, faint galaxy. Located about ...

What does it look like when galaxies collide? The Hubble Telescope captured a unique sight as two galaxies are in the process of merging. NASA says the galaxy, called NGC 1614, is about 200 million ...

NASA’s Hubble Space Telescope got a rare look at the aftermath of two cosmic collisions — and helped scientists solve a decades-old mystery. Many years ago, scientists saw a dense, bright spot near a ...

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 ...
