This video explores the enigma of dark matter, an elusive substance believed to make up most of the universe's matter. While the universe is populated by visible stars and galaxies, much of its mass ...

Cosmic voids are different. These vast expanses contain very little matter. In such places, the vacuum of space-time itself becomes the dominant component. If you were positioned at the center of a ...

Modern astrophysics has revealed a universe filled with black holes, neutron stars, hypernova explosions, and vast cosmic structures. Yet scientists believe that about 95% of the universe is made of ...

After 25 years of planning, six years of data collection, and six more years of analysis, scientists have published a portion of the final results of the Dark Energy Survey (DES) — the largest, most ...

Dark energy is one of those cosmological features that we are still learning about. While we can't see it directly, we can most famously observe its effects on the universe—primarily how it is causing ...

Michael S Turner argues that the next breakthrough in particle physics and cosmology may be just around the corner.

Researchers at the Department of Energy's Oak Ridge National Laboratory are helping to pave a path for the eventual discovery of dark matter. With new approaches to measurement in the quantum realm, ...

Using the 10-meter Hobby-Eberly Telescope in the US, astronomers have detected a subtle, hidden glow from 9 to 11 billion ...

Astronomers have just identified what appears to be a cosmic anomaly: a faint galaxy with so few visible stars that, according to calculations, as much as 99.9 percent of its mass is dark matter. The ...

Two of the world’s most powerful space telescopes have joined forces to produce a stunning new image of the Cat’s Eye Nebula, one of the most visually complex objects in the known universe. The ...

For years, cosmologists have argued over a simple question with an awkward answer: How fast is the universe expanding right now? The expansion rate, called the Hubble constant, ought to come out the ...

In recent months, Ireland became an associate member of Cern, the European Organisation for Nuclear Research. This is a very welcome development for physicists, engineers and computer scientists ...
