A U.S. Department of Energy (DOE) environmental study has determined that building and operating the proposed Long Baseline Neutrino Facility (LBNF) and Deep Underground Neutrino Experiment (DUNE) will not have a significant impact on the environment.

These physics-themed jack-o’-lanterns come with extra brains.

Symmetry has launched a brand new magazine. We’ve simplified and updated our webpages to help you find what you’re looking for, to guide your attention to our best art and photography, and to give you a better reading experience.

The forthcoming Mu2e experiment at Fermilab will kidnap muons and trap them in aluminum atoms. But what exactly happens when you shoot a muon at an aluminum foil? While Mu2e is under construction, its scientists are already getting some valuable answers from a smaller accomplice: AlCap.

Physicist Jennifer Gimmell shares her love of physics with her students.

Symmetry sits down with Lindsay Olson as she wraps up a year of creating art inspired by particle physics.

Deep in the dense core of a black hole, protons and electrons are squeezed together to form neutrons, sending ghostly particles called neutrinos streaming out. Matter falls inward. In the textbook case, matter rebounds and erupts, leaving a neutron star. But sometimes, the supernova fails, and there’s no explosion; instead, a black hole is born. Scientists hope to use neutrino experiments to watch a black hole form.

Ghostlike subatomic particles called neutrinos could hold clues to some of the greatest scientific questions about our universe: What extragalactic events create ultra-high-energy cosmic rays? What happened in the first seconds following the big bang? What is dark matter made of?

Is it possible that these fundamental building blocks of atoms have a finite lifetime?

For physicists, seeing is not always believing.
