Astrophysicist Probes Cosmic 'Dark Matter Detector'

An astrophysicist is searching the light coming from a distant, and extremely powerful celestial object, for what may be the most elusive substance in the universe: dark ...

Scientists Precisely Measure Total Amount of Matter in the Universe

A top goal in cosmology is to precisely measure the total amount of matter in the universe, a daunting exercise for even the most mathematically proficient. Scientists have now done just ...

Big Answers from Tiny Particles

Physicists demonstrate a theoretical mechanism that would explain the tiny value for the mass of neutrinos and point out that key operators of the mechanism can be probed by current and future ...

Cosmic Bursts Unveil Universe's Missing Matter

Astronomers have used mysterious fast radio bursts to solve a decades-old mystery of 'missing matter', long predicted to exist in the Universe but never detected -- until now. The ...

Exoplanet Climate 'Decoder' Aids Search for Life

After examining a dozen types of suns and a roster of planet surfaces, astronomers have developed a practical model - an environmental color ''decoder'' - to tease out climate ...

No Evidence of an Influence of Dark Matter on the Force Between Nuclei

Although most of the universe is made up of dark matter, very little is known about it. Physicists have used a high-precision experiment to look for interaction between dark matter and normal ...

Seeing the Universe Through New Lenses

A new study revealed hundreds of new strong gravitational lensing candidates based on a deep dive into data. The study benefited from the winning machine-learning algorithm in an international ...

Hayabusa2 Reveals More Secrets from Ryugu

In February and July of 2019, the Hayabusa2 spacecraft briefly touched down on the surface of near-Earth asteroid Ryugu. The readings it took with various instruments at those times have given ...

Could Dark Matter Be Hiding in Existing Data?

A new study suggests new paths for catching the signals of dark matter particles that have their energy absorbed by atomic ...

Satellite Galaxies of the Milky Way Help Test Dark Matter Theory

Physicists report tiny satellite galaxies of the Milky Way can be used to test fundamental properties of 'dark matter' -- nonluminous material thought to constitute 85% of matter in the ...

Looking for Dark Matter

Dark matter is thought to exist as 'clumps' of tiny particles that pass through the earth, temporarily perturbing some fundamental constants. A new article sets out two novel methods for ...

Belle II Yields First Results in Search of the Z' Boson

The Belle II experiment started about one year ago. The work deals with a new particle in the context of dark matter, which accounts for about 25 percent of the ...

Doubts About Basic Assumption for the Universe

No matter where we look, the same rules apply everywhere in space: countless calculations of astrophysics are based on this basic principle. A recent study, however, has thrown this principle into ...

The Milky Way's Satellites Help Reveal Link Between Dark Matter Halos and Galaxy Formation

Just like we orbit the sun and the moon orbits us, the Milky Way has satellite galaxies with their own satellites. Drawing from data on those galactic neighbors, a new model suggests the Milky Way ...

Looking for Dark Matter Close to Home

Eighty-five percent of the universe is composed of dark matter, but we don't know what, exactly, it ...

Astronomers Use Slime Mould to Map the Universe's Largest Structures

The behaviour of one of nature's humblest creatures and archival data from the NASA/ESA Hubble Space Telescope are helping astronomers probe the largest structures in the ...

Astronomers Use Slime Mold Model to Reveal Dark Threads of the Cosmic Web

A computational approach inspired by the growth patterns of a bright yellow slime mold has enabled a team of astronomers and computer scientists to trace the filaments of the cosmic web that connects ...

'Axion' Particle Solves Three Mysteries of the Universe

A hypothetical particle called the axion could solve one of physics' great mysteries: the excess of matter over antimatter, or why we're here at ...

Scientists Shed Light on Mystery of Dark Matter

Nuclear physicists are putting forward a new candidate for dark matter -- a particle they recently discovered called the d-star ...

Simulating a Universe in Which Newton's Laws Are Only Partially Valid

For the first time, researchers have simulated the formation of galaxies in a universe without dark matter. To replicate this process on the computer, they have instead modified Newton's laws of ...

Taking the Temperature of Dark Matter

Warm, cold, just right? Physicists are using gravitational lensing to take the temperature of dark matter, the mysterious substance that makes up about a quarter of our ...

Connecting the Dots in the Sky Could Shed New Light on Dark Matter

Astrophysicists have come a step closer to understanding the origin of a faint glow of gamma rays covering the night sky. They found that this light is brighter in regions that contain a lot of ...
