New galaxy simulations could help reveal the origins of the Milky Way and provide clues in the decades-long search for dark matter, researchers say.

Towns and cities create an orange glow on the horizon at night. It's so widespread that it even disturbs sea creatures.

New models could inform researchers working to get the very first picture of Sagittarius A*, the supermassive black hole at the Milky Way's center.

New techniques are being used to transform images from Hubble into spectacular 3D visualisations.

The Milky Way may be catapulting stars into its outer galactic halo, researchers say. The finding could change how we think about how star systems are born.

The blast in the Ophiuchus galaxy cluster left a cavity 15 times bigger than our Milky Way galaxy.

"This is the first time we have been able to determine when such a merger happened."

A new composite image of the Milky Way appears to contain a cosmic candy cane.

"The velocity of the discovered star is so high that it will inevitably leave the galaxy and never return."

New research puts Einstein's theories of relativity to the test in a unique laboratory—the black hole at the center of the Milky Way.
