Astronomers have found a vast loop-like structure, 20 light years across, adjacent to the most massive star-forming region known in our galaxy. The loop, which was observed in X-ray wavelengths, is 15 ...

Particle accelerators have been responsible for revolutionary scientific breakthroughs, but the tech behind them isn't as ...

The ATLAS Collaboration observed photons elastically scattering from other photons — an effect predicted by quantum electrodynamics over 80 years ago. Because the coupling at each photon–charged ...

WASHINGTON — Preliminary results from two experiments suggest something could be wrong with the basic way physicists think the universe works, a prospect that has the field of particle physics both ...
