This merger event occurred during a time when the universe was just beginning to form structures—a period when stars, galaxies, and black holes were still in formation. The close proximity of the ...

A massive collision of galaxies sparked by one travelling at a scarcely-believable 2 million mph (3.2 million km/h) has been seen in unprecedented detail by one of Earth's most powerful telescopes.

Galaxy’s petal-like structures came from collision A cosmic crash of two huge masses of stars, gas and dust probably gave way to structure of star clusters ...

A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA's Hubble Space Telescope.

Back to Article List Astronomers pin down galaxy collision rate The galaxy merger rate is one of the fundamental measures of galaxy evolution, yielding clues to how galaxies bulked up over time.

Astronomers have unveiled the most detailed image ever taken of the collision of two clusters of galaxies.

As Earthlings, the kind of space collision we typically fear the most is one between an asteroid and our home planet. Depending on the size … ...

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ...

Our galaxy is on course to crash into one of its neighbours – and it is not unique. New Scientist takes a look at other galaxies on a collision course ...

The image of the galaxy merger was discovered by a citizen science project.

When you think about gargantuan phenomena such as the collision of galaxies, it might be tempting to imagine it as some sort of cosmic cataclysm, with stars crashing and exploding, and destruction ...

Called the Antennae, they are among the nearest examples of colliding galaxies. They also appear at a relatively early stage of the collision process, which began about 500 million years ago.
