LHC restart timeline

Physics is just around the corner for the LHC. Follow this timeline through the most exciting moments of the past few months.


LHC achieves record-energy collisions

The Large Hadron Collider broke its own record again in 13-trillion-electronvolt test collisions.


The latest trials at the LHC smashed particles with vastly more energy than ever before.

It may be possible to detect plutonium factories from a distance through neutrinos.

Viewing our turbulent universe


Construction has begun for the CTA, a discovery machine that will study the highest energy objects and events across the entire sky.


Ten things you may not know about the Higgs boson

This year, results from the Large Hadron Collider in Europe and the Tevatron in the United States will either prove or refute the existence of the Standard Model Higgs particle, a keystone in theor


Happy Webiversary

Twenty years ago, physicists, computer scientists, and a librarian at what is now SLAC National Accelerator Laboratory opened the first website in North America.


The cosmic-ray riddle

Data from the world’s most powerful particle colliders should shed light on a 100-year-old astrophysics mystery, but even they cannot explain the perplexing properties of the universe’s most energe


The brain behind TV's The Big Bang Theory

For those who live, breathe and laugh physics, one show entangles them all: The Big Bang Theory.


Cosmic microwave background

Cosmic microwave background is the oldest light in the universe. It was set free when the universe was a mere 380,000 years old and provides a window to the early universe.


W precision measurement

The W boson mass is one of the fundamental ingredients that scientists use to calculate particle physics properties, such as the most likely mass of the soughtafter Higgs particle.


Do you know why I pulled you over?

Exceeding the speed of light has consequences, even——especially?——for neutrinos.


Going public

How the public release of data from the Fermi Gamma-ray Space Telescope’s main instrument has affected the hundreds of researchers who use it—and resulted in more and better science.
