Way back when the world was young and I still attended physics conferences, I got very excited by galactic cosmic rays. There seemed to be more cosmic rays than expected coming from the center of our ...

A vast cosmic formation known as the Big Ring has been detected deep in space, stretching about 1.3 billion light-years ...

Astronomers have achieved one of the most precise measurements ever made of the Milky Way’s distant spiral arms, revealing ...

A group of researchers at the University of Waterloo and the University of British Columbia have discovered a potential "cosmic glitch" in the universe's gravity, explaining its strange behavior on a ...

A computational approach inspired by the growth patterns of a bright yellow slime mold has enabled a team of astronomers and computer scientists at UC Santa Cruz to trace the filaments of the cosmic ...

A new analysis of the South Pole-based telescope's cosmic microwave background observations has all but ruled out several popular models of inflation. Physicists looking for signs of primordial ...

Abstract: Cosmic variance is the intrinsic scatter in the number density of galaxies due to fluctuations in the large-scale dark matter density field. In this work, we present a simple analytic model ...
