"We have never observed such a high-energy neutrino before, and if it turns out to come from cosmic accelerators like blazars, it would give us new insight into how these objects can emit particles at ...

Our planet is under a constant bombardment of radiation—from space. Well, maybe it’s not as scary as that makes it seem. “Radiation” is a catchall term astronomers use for forms of light—including ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? Here’s what you’ll learn when you read this story: The Large Hadron Collider (LHC) is ...

Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists ...

Physicists just discovered a brand-new particle that appears to be an exotic cousin to the protons and neutrons that make up atoms. Those mundane subatomic particles are made up of even smaller ...

A new particle has popped into existence at CERN’s Large Hadron Collider, a heavier proton-like particle that contains two charm quarks. Protons and neutrons are examples of a class of particles ...

As foretold, the Relativistic Heavy Ion Collider—among the most powerful heavy-ion colliders in the world, second only to CERN’s LHC—ran its final particles and ceased operations last Friday. This is ...

The Sun unleashes a torrent of charged particles. Some of them slam into the Earth’s atmosphere, triggering breathtaking auroras in the night sky. But for equipment that’s orbiting our planet in outer ...

I peeked in on the house-sized particle detector known as STAR just after it took its last-ever snapshot of one of the most extreme types of fireball ever created. Inside, the conditions just after ...

Chronic exposure to pollution from wildfires has been linked to tens of thousands of deaths annually in the United States, according to a new study. The paper, published Wednesday in the journal ...

In July 2012, physicists at the Large Hadron Collider (LHC) in Europe triumphantly announced the discovery of the Higgs boson, the long-sought linchpin of the subatomic world. Interacting with Higgs ...
