Scientists have developed a new particle detector that can measure incredibly short bursts of electrons lasting just one trillionth of a second, or one picosecond. The breakthrough could help next-generation particle accelerators reveal how materials, chemicals and biological systems behave at the atomic level. The new detector was created by the Advanced Accelerator Diagnostics Collaboration, […]

Millions of years ago, a massive star exploded somewhere far away in our galaxy. During this violent event, called a supernova, the dying star blasted huge amounts of matter into space. These materials included carbon, nitrogen and oxygen—the essential ingredients for life—as well as many other elements, some as heavy as iron. The explosion itself […]
