The ABCs of particle physics

Take an interactive animated journey through the particle physics alphabet. Accelerators and black holes and cryostats, oh my! We know particle physics can seem daunting at times, but everything’s more fun to learn when it rhymes. So...Show More Summary

A new X-ray eye in the sky

The recently launched Hitomi spacecraft will look for answers from the universe's violent phenomena. Although the star-covered night sky is regarded by many as a synonym of serenity, the cosmos is in fact a rather hostile place. It hosts many extreme environments that would instantaneously eradicate any life nearby. Show More Summary

Casting a net for neutrinos

The KM3NeT experiment will catch the elusive particles using the Mediterranean Sea. Like ordinary telescopes, KM3NeT operates in darkness—but there the resemblance ends. The Km 3 Neutrino Telescope (where km 3 means a cubic kilometer)...Show More Summary

Test of DUNE tech begins

On the road to the world’s largest neutrino detector, take the “DUNE Buggy.” The planned Deep Underground Neutrino Experiment will require 70,000 tons of liquid argon, making it the largest experiment of its kind—100 times larger than...Show More Summary

Daya Bay discovers a mismatch

The latest measurements from the Daya Bay neutrino experiment in China don’t align with predictions from nuclear theory. A new result from the Daya Bay experiment has revealed a possible flaw in predictions from nuclear theory.  “Nobody expected that from neutrino physics,” says Anna Hayes, a nuclear theorist at Los Alamos National Laboratory.

LIGO sees gravitational waves

The experiment confirms the last piece of Einstein’s general theory of relativity. There’s officially a new way to look at the universe, and it’s not with a telescope. After weeks of speculation, the LIGO Scientific Collaboration confirmed...Show More Summary

Neutrinos on a seesaw

A possible explanation for the lightness of neutrinos could help answer some big questions about the universe. Mass is a fundamental property of matter, but there’s still a lot about it we don’t understand—especially when it comes to...Show More Summary

Weighing the lightest particle

Physicists are using one of the oldest laws of nature to find the mass of the elusive neutrino. Neutrinos are everywhere. Every second, 100 trillion of them pass through your body unnoticed, hardly ever interacting. Though exceedingly...Show More Summary

This radioactive life

Radiation is everywhere. The question is: How much? An overly plump atomic nucleus just can’t keep itself together.  When an atom has too many protons or neutrons, it’s inherently unstable. Although it might sit tight for a while, eventually...Show More Summary

A mile-deep campus

Forget wide-open spaces—this campus is in a former gold mine. Twice a week, when junior Arthur Turner heads to class at Black Hills State University in Spearfish, South Dakota, he takes an elevator to what is possibly the first nearly...Show More Summary

Our imperfect vacuum

The emptiest parts of the universe aren’t so empty after all. In the Large Hadron Collider, two beams of protons race around a 17-mile ring more than 1 million times before slamming into each other inside the massive particle detectors. But...Show More Summary

Is the neutrino its own antiparticle?

The mysterious particle could hold the key to why matter won out over antimatter in the early universe. Almost every particle has an antimatter counterpart: a particle with the same mass but opposite charge, among other qualities.  This seems to be true of neutrinos, tiny particles that are constantly streaming through us. Show More Summary

A speed trap for dark matter

Analyzing the motion of X-ray sources could help researchers identify dark matter signals.   Dark matter or not dark matter? That is the question when it comes to the origin of intriguing X-ray signals scientists have found coming from...Show More Summary

Exploring the dark universe with supercomputers

Next-generation telescopic surveys will work hand-in-hand with supercomputers to study the nature of dark energy. The 2020s could see a rapid expansion in dark energy research. For starters, two powerful new instruments will scan the night sky for distant galaxies. Show More Summary

Black holes

Let yourself be pulled into the weird world of black holes. Imagine, somewhere in the galaxy, the corpse of a star so dense that it punctures the fabric of space and time. So dense that it devours any surrounding matter that gets too...Show More Summary

How to wrangle a particle

Learn some particle accelerator basics from a Fermilab accelerator operator. How do you keep a particle inside of a particle accelerator? Fermilab accelerator operator Cindy Joe explains. Video of ZvrVhB_kEqA Have a burning question about particle physics? Let us know via email or Twitter (using the hashtag #asksymmetry). We might answer you in a future video!

The booming science of dwarf galaxies

A recent uptick in the discovery of the smallest, oldest galaxies benefits studies of dark matter, galaxy formation and the evolution of the universe.   Galaxies are commonly perceived as gigantic spirals full of billions to trillions of stars. Show More Summary

CERN and US increase cooperation

The United States and the European physics laboratory have formally agreed to partner on continued LHC research, upcoming neutrino research and a future collider. Today in a ceremony at CERN, US Ambassador to the United Nations Pamela...Show More Summary

LHC ends 2015 with a cliffhanger

Two LHC experiments see an unexpected bump, but scientists need more data to figure out whether it's worth getting excited about. The final Large Hadron Collider results of the year are in. A new and unexpected bump in the data has left...Show More Summary

Festive physicists

What’s it like working on experiments over the holidays? For many, the winter holiday season means a few days off, a time for family and friends and food. But for some, it means conducting massive physics experiments that don’t takeShow More Summary
