Gravitational waves measure the universe

The direct detection of gravitational waves from at least five sources during the past two years offers spectacular confirmation of Einstein's model of gravity and space-time. Modeling of these events has also provided information ...

Best of Last Year—The top Phys.org articles of 2017

It was another great year for science, particularly physics, as evidenced by a study conducted by U.K., Canadian and Italian researchers who revealed substantial evidence of a holographic universe. They published what is ...

Juno probes the depths of Jupiter's great red spot

Data collected by NASA's Juno spacecraft during its first pass over Jupiter's Great Red Spot in July 2017 indicate that this iconic feature penetrates well below the clouds. Other revelations from the mission include that ...

Seeing through walls of unknown materials

Researchers at Duke University have devised a way to see through walls using a narrow band of microwave frequencies without any advance knowledge of what the walls are made out of. Besides having obvious applications in the ...

Butterfly emerges from quantum simulation

Quantum simulators, which are special-purpose quantum computers, will help researchers identify materials with new and useful properties. This enticing future has just taken a step forward thanks to a collaboration between ...

Ultrathin and flat graphene metalenses gain more properties

On the quest for miniaturization, scientists at the Center for Integrated Nanostructure Physics, within the Institute for Basic Science (IBS, South Korea), in collaboration with researchers from the University of Birmingham ...

Solar minimum surprisingly constant

Using more than a half-century of observations, Japanese astronomers have discovered that the microwaves coming from the sun at the minimums of the past five solar cycles have been the same each time, despite large differences ...

NASA CubeSat to test miniaturized weather satellite technology

Behind every weather forecast—from your local, five-day prediction to a late-breaking hurricane track update—are the satellites that make them possible. Government agencies depend on observations from weather satellites ...
