Scientists behind a theory that the speed of light is variable - and not constant as Einstein suggested - have made a prediction that could be tested.
Researchers have created a 3D printed cosmic microwave background - a map of the oldest light in the universe - and provided the files for download.
There's been a whirlwind of commentary of late speculating that the acceleration of the expanding universe might not be real after all.
Five years ago, the Nobel Prize in Physics was awarded to three astronomers for their discovery, in the late 1990s, that the universe is expanding at an accelerating pace.
It takes a very, very clean room to build a detector sensitive enough to see the light from the beginning of the universe.
A team of astrophysicists at the University of Portsmouth have created the largest ever map of voids and superclusters in the universe, which helps solve a long-standing cosmological mystery.
The universe is not spinning or stretched in any particular direction, according to the most stringent test yet.
An experiment to explore the aftermath of cosmic dawn, when stars and galaxies first lit up the universe, has received nearly $10 million in funding from the National Science Foundation to expand its detector array in South ...
ESA's Planck satellite has revealed that the first stars in the Universe started forming later than previous observations of the Cosmic Microwave Background indicated. This new analysis also shows that these stars were the ...
An international team of astronomers has created the largest ever three-dimensional map of distant galaxies in a bid to help them understand one of the most mysterious forces in the universe.
