There is an important and unresolved tension in cosmology regarding the rate at which the universe is expanding, and ...

The past, present and future of the universe is about to be revealed in unprecedented detail by Britain’s biggest academic supercomputer called the Cosmology Machine, based at the University of Durham ...

Everything humanity has ever touched, measured, or imagined as “normal” matter is a tiny sliver of reality. Less than 5 ...

“The first thing we know about the universe is that it’s really, really big,” says cosmologist Michael Turner, who has been contemplating this reality for more than four decades now. “And because the ...

A team of astronomers using a variety of ground and space-based telescopes including the W. M. Keck Observatory on Maunakea, ...

New measurements using gravitational lensing suggest the universe’s current expansion rate does not agree with signals from ...

"It means cleaning house, narrowing the viable paths forward, and no longer spending energy on what are evidently dead ends." ...

Astronomers have assumed for decades that the Universe is expanding at the same rate in all directions. A new study based on data from ESA’s XMM-Newton, NASA’s Chandra and the German-led ROSAT X-ray ...
