First images of muon beams

A new technique has taken the first images of muon particle beams. Nagoya University scientists designed the imaging technique with colleagues in Osaka University and KEK, Japan and describe it in the journal Scientific Reports. ...

Abell 2384: Bending the bridge between two galaxy clusters

Several hundred million years ago, two galaxy clusters collided and then passed through each other. This mighty event released a flood of hot gas from each galaxy cluster that formed an unusual bridge between the two objects. ...

Chandra spots a mega-cluster of galaxies in the making

Astronomers using data from NASA's Chandra X-Ray Observatory and other telescopes have put together a detailed map of a rare collision between four galaxy clusters. Eventually all four clusters—each with a mass of at least ...

Researching the kingfisher's hydrodynamic design

Renowned for their noiseless dive, the kingfisher's iconic beak-shape has inspired the design of high speed bullet trains. Now scientists have tested beak-shape among some of the birds' 114 species found world-wide, to assess ...

NASA captures unprecedented images of supersonic shockwaves

NASA has captured unprecedented photos of the interaction of shockwaves from two supersonic aircraft, part of its research into developing planes that can fly faster than sound without thunderous "sonic booms".

Physics instructor writes book on shock waves

A sonic boom and a thunderclap may seem like different phenomena, but their behavior is the same, according to SDState Physics Instructor W. Robert Matson. This is one of the ways he explains shock waves in "Sonic Thunder," ...
