The universe seems so quiet overall, from galaxies to planets, are humans really quite lonely? The last time I stayed up late ...

Did you know that scientists have discovered that 80% of the universe is void? This is quite astonishing! When we usually ...

A new set of data strengthens the case that dark energy’s influence on the universe—long believed to be constant—is actually changing over cosmic time.

Astronomers using NASA’s James Webb Space Telescope have stumbled upon a puzzling population of galaxies that look far too bright for their age. In four patches of sky, covering more than 500 ...

Hidden deep in space, the Great Attractor is a gravitational anomaly so powerful it drags entire galaxies toward it, including our own Milky Way.

Two colliding galaxies have been found to be reorganizing their dwarf satellites, potentially solving a major conundrum plaguing the standard model of cosmology.

A cosmic dance could be the future of the Milky Way as it tracks a course to collide with neighboring galaxies, a University of Queensland survey has found. The paper is published in the Monthly ...

We usually think of satellites as small objects orbiting planets or stars. But in the broader universe, galaxies themselves can have satellites—smaller galaxies bound by gravity that orbit a ...

There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to astronomers.

Our Milky Way could have many more satellite galaxies than we've detected so far. They're just too faint to be seen.

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan&quot ...
