Faint structures play a crucial role in cosmic development, and scientists are only just beginning to grasp their full extent ...

A physicist proposes that the universe might not be empty but act like a viscous fluid, resisting expansion. This bold idea ...

An international team led by the University of Oxford has identified one of the most massive and unusual structures in the Universe, a giant cosmic filament located 140 million light-years away. This ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's ...

New data from major dark-energy observatories suggest the universe may not expand forever after all. A Cornell physicist calculates that the cosmos is heading toward a dramatic reversal: after ...

It’s always amazing, and more than a little humbling, when the universe reminds us that our “common sense” is provincial, falling apart on cosmic scales. If you’re on the surface of Earth—and I’m ...

This enormous chain of hundreds of galaxies—a cosmic filament—is twisting through space 400 million light-years away ...

When you look up at the night sky, it seems deep black with bright stars scattered across it. That familiar view leads many ...

Neutrino particles have extremely small masses, yet there are so many of them that they carve out the large-scale structure ...

A physicist proposes that the universe is not empty space, but is a viscous fluid, fueling the expansion and contraction we see.

A doctoral student from the University of Sydney’s School of Physics re-created a little bit of the universe in a bottle.

A UK startup wants to build a cosmic radio station in the Moon’s orbit to listen to radio waves from the early universe. Blue Skies Space has secured a contract from the Italian Space Agency to design ...
