A newly revealed cosmic image shows two galaxy clusters colliding as one. Nicknamed the Champagne Cluster, it offers rare ...

In a groundbreaking astronomical discovery, researchers have unveiled a cosmic event of immense scale: a trio of galaxies, each hosting a supermassive black hole, is on a collision course. Located ...

The team found only a 2 percent probability that the galaxies will collide in the next five billion years. In slightly over half of the simulated scenarios, Andromeda and the Milky Way experience at ...

The James Webb Space Telescope has peered through cosmic dust to reveal new details and a stunning image of a rare type of galaxy. The space observatory's latest image shows the Cartwheel galaxy, a ...

Two galaxies are merging in the deep cosmos. And the James Webb Space Telescope just captured a vivid view of the scene. The interacting galaxies, called Arp 107, collided hundreds of millions of ...

Examples of merging galaxies containing a heavily obscured growing supermassive black hole observed by the Hubble Space Telescope. The top panels show nearby galaxies at ~500 million light-years from ...

As the Large Magellanic Cloud drifts closer to the Milky Way, its newly discovered black hole may one day encounter ...

Cosmic chaos: In a galaxy far, far away, two humongous black holes are going head-to-head in a gravitational grappling match. NASA's iconic Hubble telescope and the Chandra X-ray Observatory just ...

The Milky Way and Andromeda galaxies may not collide. Collision probability depends on the inclusion of nearby galaxies in calculations. Current measurements of galaxy masses have significant ...

Scientists have long thought the Milky Way galaxy would someday collide with its closest neighbor, Andromeda. However, new research suggests the future of our cosmic home is more uncertain than ...

According to the prevailing “cold dark matter” theory of the evolution of the universe, every galaxy is surrounded by a halo of dark matter that can only be detected indirectly by observing its ...
