The early universe

How is it possible to look at the earliest moments of the universe?


SeaQuest seeks the secrets of the proton

Late last week, the SeaQuest experiment began exploring the structure of protons and the behavior of the particles of which they're made.


Computer tennis, anyone?

Brookhaven Lab’s 1958 innovation earns a prominent place in the history of video games.


The future of US particle physics

This summer, more than 700 particle physicists came together to dream big about the next steps in their studies of energy, matter, space and time.


Why particle physics matters

Particle physics has revolutionized the way we look at the universe.


The big questions

Through the “Snowmass” process, US particle physicists thoroughly considered the field’s most compelling unanswered questions and ways to realistically answer them.


Unanswered questions

Do you think scientists have the answers to all the questions? As these researchers admit, there’s still so much to discover. Particle physics is brimming with mysteries and unknowns.


The great physics quest

In their search for fundamental truths, particle physicists have a lot in common with explorers everywhere. 


Just how weak is the weak force?

Using a unique technique, the Q-weak collaboration has found the value of the weak force to be in agreement with theory—so far.


Physicists chart path forward

Through the “Snowmass” process, particle physicists discussed the field’s biggest unanswered questions and thoroughly analyzed the tools needed to answer them.


Big move

For a little over a month this summer, a huge electromagnet slowly journeyed from New York to Illinois, offering great photo opportunities along the way.


Scientists look to next decades in US particle physics

From the output of the "Snowmass" meeting, US particle physicists will chart a path to answering some of science’s most intriguing questions.


Giant electromagnet arrives at Fermilab

The 50-foot-wide electromagnet for the Muon g-2 experiment has completed its five-week journey from New York to Illinois.


T2K experiment catches neutrinos in the act

For the first time, an experiment has definitively observed the appearance of neutrinos that have changed from one type to another.


GERDA investigates the identity of the neutrino

Scientists on the GERDA experiment have placed new limits on a process that could reveal the true character of the neutrino.
