New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite ...

New research suggests that the Milky Way may host more satellite galaxies than previously predicted, thanks to advanced ...

In summer, we face toward the Milky Way's hub in the Teapot constellation, home to the galaxy's supermassive black hole.

But in the past two decades, new types of black holes have been seen and astronomers are beginning to understand how they ...

Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to ...

The image of supermassive black hole Sagittarius A * was created using data from the Event Horizon Telescope Collaboration.

New research suggests sub-stellar objects called dark dwarfs could glow forever on dark matter energy. Could they reveal secrets about the universe’s hidden mass?

We measure the extremely long distances between things in space by light years. A light year is the distance that light travels in one Earth year. Light travels at about 300,000 kilometres per second.

This year, the Buck Moon follows Earth's aphelion, the point in its orbit farthest from the Sun, by just a few days, ...

Jets are cosmic phenomena that could happen in a couple of ways. Now, researchers have found one larger than the Milky Way, ...

"Theories involving substantial formation of stars prior to or together with the black hole formation and growth are very ...

Deep within the Milky Way’s core, researchers have uncovered cold gas clouds racing through a superheated galactic wind.
