Invisible Dark Matter May Show Up in GPS Signals
GPS satellites are crucial for navigation, but now researchers think this technology could be used for an unexpected purpose: finding traces of enigmatic dark matter that is thought to lurk throughout the universe. Physicists estimate there is nearly six times as much dark matter in the universe as there is...

Dark Matter Illuminated in New High-Resolution Maps
BALTIMORE — In the universe, dark and light tend to cluster together, according to new maps that chart the location of dark matter over a large portion of the sky. The new maps show that in some places there are large amounts of dark matter, while in others it is...
Mysterious Dark Matter May Not Always Have Been Dark

Mysterious Dark Matter May Not Always Have Been Dark
Dark matter particles may have interacted extensively with normal matter long ago, when the universe was very hot, a new study suggests. The nature of dark matter is currently one of the greatest mysteries in science. The invisible substance — which is detectable via its gravitational influence on normal matter...
Dark Matter 'Hairs' May Surround Earth

Dark Matter 'Hairs' May Surround Earth
Earth may sport a thick coat of superlong dark matter hairs, a new study suggests. Astronomers think dark matter — a mysterious, invisible substance that neither emits nor absorbs light, and is about six times more common than normal matter — forms fine-grained but incredibly long streams throughout the universe....
Dark Matter May Be Made Up of Superheavy Particles

Dark Matter May Be Made Up of Superheavy Particles
Dark matter could be made of particles that each weigh almost as much as a human cell and are nearly dense enough to become miniature black holes, new research suggests. While dark matter is thought to make up five-sixths of all matter in the universe, scientists don't know what this...
This Weird Galaxy Is Actually 99.99 Percent Dark Matter

This Weird Galaxy Is Actually 99.99 Percent Dark Matter
Astronomers have discovered a galaxy as big as the Milky Way that consists almost entirely of dark matter, a mysterious and invisible substance that scientists have been trying to figure out for decades. Only one-hundredth of one percent of the galaxy is ordinary, visible matter like stars and planets. The...

Dark Matter Just Got Murkier
Don Lincoln is a senior scientist at the U.S. Department of Energy's Fermilab, America's largest Large Hadron Collider research institution. He also writes about science for the public, including his recent The Large Hadron Collider: The Extraordinary Story of the Higgs Boson and Other Things That Will Blow Your Mind...
Universe May Have Lost 'Unstable' Dark Matter

Universe May Have Lost 'Unstable' Dark Matter
The early universe may have contained more dark matter than there is today, new research suggests. The findings could help scientists better understand what the universe was like just after the Big Bang, researchers said. Most of the matter in the universe seems to be invisible and largely intangible; it...

Captured: First 'Image' of the Dark Matter That Holds Universe Together
For decades, scientists have tracked hints of a thread-like structure that ties together galaxies across the universe. Theories, computer models, and indirect observations have indicated that there is a cosmic web of dark matter that connects galaxies and constitutes the large-scale structure of the cosmos. But while the filaments that...
'Excess' Gamma-Rays Likely Not Sign of Dark Matter After All

'Excess' Gamma-Rays Likely Not Sign of Dark Matter After All
A promising lead about the nature of elusive dark matter may have just dried up. A mysterious abundance of gamma-rays — the highest-energy light in the universe — at the Milky Way's center is likely being produced by fast-spinning stellar corpses called pulsars, rather than bits of dark matter slamming...

A Space Magnet, Hunting Dark Matter, Turns Up Juicy Secrets of Cosmic Rays
Somewhere far away in the universe, a star bursts and a cascade begins. Energy and small bits of matter speed away in every direction from the blooming supernova. They impact planets and other stars and crash into interstellar media, and some small portion of them reach Earth. These are primary...
Astrophysicists Claim They Found a 'Galaxy Without Dark Matter'

Astrophysicists Claim They Found a 'Galaxy Without Dark Matter'
Here's a problem: The universe acts like it's a lot more massive than it looks. Take galaxies, those giant, spinning masses of stars. The laws of motion and gravity tell us how fast these objects should turn given their bulk. But observations through telescopes show them spinning way faster than...
Is Dark Matter Made Up of Mini Black Holes from the Big Bang?

Is Dark Matter Made Up of Mini Black Holes from the Big Bang?
Dark matter, the mysterious extra mass in the universe that emits no light yet exerts a gravitational pull, may actually be made up of primordial black holes that originated with the Big Bang. And these mini black holes can thank the Higgs boson for their birth — at least according...
