Astronomers have long struggled with a troubling puzzle: a significant portion of normal matter in the universe appeared to ...

The halo is more extended that astronomers originally thought, and contains enough hydrogen gas to resolve the problem of the ...

A slowly spinning universe could resolve a puzzle in physics known as the Hubble tension, a new model suggests.

Who knew that magnetic fields could be so useful? Astronomers are able to use magnetic fields to map our environment within ...

A faint cosmic spin – one rotation per 500 billion years – could resolve the stubborn Hubble tension by tweaking standard ...

About half of the non-dark matter in the universe cannot be accounted for by stars and galaxies alone. Now, scientists say ...

The rotating model, which does not break any known law of physics, suggests the universe could spin around once every 500 billion years. This would be far too slowly to detect easily, but enough to ...

"We've always known that we need something to complete the puzzle, but we haven't really known what shape or form those ...

A never-before-seen image of the cosmic microwave background, combining data from the Atacama Cosmology Telescope (ACT) and ...
