At LIGO, three’s a trend

The third detection of gravitational waves from merging black holes provides a new test of the theory of general relativity.

Solar neutrinos

Deep in the Homestake Gold Mine in Lead, South Dakota, during the early 1970s, Ray Davis monitored a 100,000-gallon tank of perchloroethylene, a chlorine-rich dry-cleaning chemical.

Soudan mural

This mural in the Soudan Underground Laboratory, located in Minnesota half a mile underground, was designed by artist Joseph Giannetti. Its theme is matter and energy, and--more specifically--neutrino physics.

The decade of the neutrino

Speaking experimentally, the past decade has been the "Decade of the Neutrino." It produced neutrino experiments across three continents, going from the lab, to the nuclear reactor, to the atmosphere, to the sun, and back to the nuclear reactor.

Neutrino mixing

Waves describe some of the most extraordinary phenomena in the world. Waves can be simple—the sound of a flute playing a sustained, single note—or they can be complicated mixtures—a musical chord, for example, which is a combination of many sound waves.

Virtual structure

As the newly-appointed Director of the Global Design Effort (GDE) for the proposed International Linear Collider (ILC), Barry Barish will lead teams of scientists worldwide in the research and development projects advancing the design of the next-generation discovery machine in high-energy physic

The elusive neutrino

Not only are neutrinos hard to catch, but they also change form as they travel through space. New experiments hope to understand their chameleonic nature.

Bubble chambers are back

Bubble chambers, once at the forefront of particle detection and then relegated to the history books, are coming back.

Searching for the neutrino's identity

Neutrinos are like no other particle in the universe. The more we learn about these "little neutral ones," the less we seem to understand them. Physicists do not even yet know what type of particle the neutrino is.
