A CP-symmetry transformation swaps a particle with the mirror image of its antiparticle. The LHCb collaboration has observed a breakdown of this symmetry in the decays of the D0 meson (illustrated by the big sphere on the right) and its antimatter counterpart, the anti-D0 (big sphere on the left), into other particles (smaller spheres). The extent of the breakdown was deduced from the difference in the number of decays in each case (vertical bars, for illustration only) . Credit: CERN

Why matter is so widespread in the universe

Physicists in the College of Arts and Sciences at Syracuse University have confirmed that there is a markedly different decaying process between matter and...

Wonderful!! 83 supermassive black holes found in the early universe

Supermassive black holes, found at the centers of galaxies, can be millions or even billions of times more massive than the sun. While they...
NASA's Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission is targeted to launch in 2023. SPHEREx will help astronomers understand both how our universe evolved and how common are the ingredients for life in our galaxy’s planetary systems. Credits: Caltech

NASA now wants to explore the origin of the Universe

In a new mission, NASA has decided to explore the origin of the universe- solving a long term mystery- how our universe evolved and how...

Universe’s stuff keeps changing

The piece of the universe—the components that are the building blocks for all of matter—is consistently changing and regularly evolving, on account of the...
Measuring the expansion of the Universe

Active Galaxies point to new physics of cosmic expansion

Exploring the history of the universe with a large sample of distant ‘active’ galaxies observed by ESA’s XMM-Newton, a team of astronomers found there...

New quantum structures in super-chilled helium may mirror early days of universe

Helium remains a liquid at atmosphere weight notwithstanding when chilled down to absolute zero, at which every other material freeze solid. In addition to...
Missing dark matter from the early universe found by astronomers

Missing dark matter from the early universe found by astronomers

For close on a century, researchers have estimated that the universe contains more matter than can be directly observed known as dark matter. They...

Our universe may be sitting on a bubble within an extra dimension

We know that our universe is expanding at an accelerating rate, but what causes this growth remains a mystery. The most likely explanation is...
