NASA's James Webb Space Telescope (JWST) has produced a new image of the Bullet Cluster, which is a titanic collision between ...

According to our best possible understanding of the universe, regular matter is only a small fraction of the matter-energy ...

Because it doesn't interreact with light or electromagnetism, dark matter exists to us only through its influence on visible ...

Powerful particle accelerators like the Large Hadron Collider have helped scientists understand the nature of regular matter through high-energy particle collisions, but dark matter can't be ...

Evidence that the universe is rotating was recently delivered by the James Webb Space Telescope (JWST), which found that ...

Particle accelerators like the Large Hadron Collider have failed to turn up potential dark matter candidates, but could galaxy cluster smashes be used as cosmic dark matter colliders?

The South Pole Telescope has mapped our skies in more detail than ever before, strengthening our understanding of dark energy ...

Dark matter is a real pain in the neck. The term dark matter itself refers to a hypothetical substance that seems to solely ...

The game-changing Vera C. Rubin Observatory will collect more astronomical data in its first year than all other telescopes ...

Dark energy, the new measurement suggests, may not resign our universe to a fate of being ripped apart across every scale, from galaxy clusters down to atomic nuclei. Instead, its expansion could ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion.

An image from the Dark Energy Camera (DECam) shows a striking celestial sight: the Southern Pinwheel Galaxy, a gorgeous face-on galaxy that is one of the closest and brightest barred spiral ...
