Cosmic rays are made primarily of protons with a few electrons sprinkled in, and they can reach energies even higher than ...

The age of laser weapons looks to have officially dawned. Rafael Advanced Defense Systems says that, for the first time in history, a high-energy laser system has been used to destroy multiple drone ...

Supermassive black holes at the hearts of active galaxies may be churning out a lot of the universe’s high-energy neutrinos. “I would say that they can be the major contributor,” says astronomer ...

Scientists have demonstrated a new way to use high-energy particle smashups at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy (DOE) Office of Science user facility for nuclear ...

Visions of swarms of small, inexpensive drones filling the skies or skimming across the waves are motivating militaries to develop and deploy laser weapons as an alternative to costly and potentially ...

An artist's rendition of the detection of the cosmic ray by the Telescope Array experiment. When high-energy cosmic rays reach Earth's atmosphere, they collide with and break apart atomic nuclei, ...

The goal of high energy physics (also known as particle physics) is to determine the most fundamental building blocks of matter and to understand the interactions between these particles. The ...
