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 ...

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

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" ...

Hubble Space Telescope images have revealed a second massive collision between planetary bodies orbiting the nearby star ...

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 / ...

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 ...

Hubble, now 35 years old, is still the only telescope able to perform such observations. Researchers stress planning for a new ultraviolet observatory to continue this work. That future instrument ...
