NASA's Fermi Finds Vast 'Halo' Around Nearby Pulsar

It's so huge and close to Earth, it would appear 40 times as large as a full Moon in the sky — if we could see it.

Neutron star's "halo" could help solve antimatter mystery

Positron Electron

Astrophysicists have detected a gamma-ray "halo" around a neutron star, and they think it could explain the abundance of positrons near Earth.

Neutron Star’s “Halo” Could Help Solve Antimatter Mystery

This could explain the abundance of positrons near Earth.

Scientists are challenging long-held assumptions about the universe to hunt down dark matter.

New research: antimatter could be portal to "dark universe"

Exhausting Options

A team of physicists attempted a bizarre new way to spot dark matter: using antimatter probes. It hasn't worked yet, but the scientists have some ideas.

New Research: Antimatter Could Be Portal to “Dark Universe”

Scientists have a new plan to spot dark matter.

Step 1, slow the particles way down. Step 2, study them. Step 3, understand the universe.

We’re almost able to cool antimatter. Here’s why that’s a big deal.

Hard Science

Researchers from CERN have just moved one step closer to cooling antimatter, which should make it easier for us to study the mysterious substance.

We’re Almost Able to Cool Antimatter. Here’s Why That’s a Big Deal.

We barely know what antimatter is, and that's why we need to get a better look at it.

Transporting antimatter comes with some unique challenges — like its tendency to explode at any contact with matter.

CERN researchers are preparing to transport antimatter between labs

Extensive preparation is needed to transport antimatter even a few hundred meters, given that it explodes upon contact with any matter.

CERN Researchers Are Preparing to Transport Antimatter Between Labs

They just have to smooth out some kinks, like preventing it from exploding en route.

CERN Researchers Are Planning to Trap and Truck Antimatter From One Facility to Another

We still don't know where all of this antimatter is coming from.

Is dark matter decay causing antimatter to smash into Earth?

A new source has been proposed for a mysterious stream of antimatter particles hitting Earth: dark matter decay, though this remains contentious.

Is Dark Matter Decay Causing Antimatter to Smash into Planet Earth?

This dark matter theory doesn't sit well with everyone.

These observations of tiny particles could have enormous implications.

We may finally have a way to solve the cosmos' antimatter mystery

scientists may be able to solve one of the universe's greatest mysteries if they can disprove current observations that electrons are round.

We May Finally Have a Way to Solve the Cosmos' Antimatter Mystery

Why didn't our universe destroy itself after the Big Bang?

We May Finally Have a Way to Solve the Cosmos’ Antimatter Mystery

A team of researchers at CERN once again attempted to figure out why the universe exists despite a fundamental symmetry that should have resulted in instant annihilation. Unfortunately, their study of the magnetism of protons and antiprotons didn't turn up any differences.

CERN Research Finds “The Universe Should Not Actually Exist”

According to our understanding of physics, the universe doesn't make sense. 

Someday we could use warp drives like the Star Trek crew.

Off World

Humans have been dreaming of interstellar travel for decades. These are our best chances of making it a reality.

Here Is the Future of Interstellar Spacecraft

Since Project Daedalus in 1973, humans have been designing craft to fly between the stars.

This discovery could help us answer some of the largest conundrums in physics today.

Researchers working with CERN's ALPHA collaboration have created and observed an antihydrogen atom and its spectral lines.

Scientists Just Made a Major Discovery by Observing Antihydrogen Atoms

"By studying the properties of anti-atoms we hope to learn more about the Universe in which we live."

We're learning more about the universe we live in.

For the first time, researchers have found a way to capture fine details of antihydrogen's spectral lines and show they are in fact identical to hydrogen.
