An international team of astronomers announces the first-ever discovery of a star in the Milky Way showing distinct green spectral features, pointing to a new high-resolution spectroscopic technique that reveals a stellar surface chemical anomaly. The discovery opens new observational windows for stellar evolution, surface chemistry, and exoplanet search research, and places new technical demands on global observatories, space telescopes, and spectroscopic data processing pipelines.

The 2026 Nobel Prize in Physics has been awarded to University of Wisconsin-Madison Professor Francis Halzen for his pioneering work on detecting high-energy astrophysical neutrinos. The Nobel Committee stated his work has opened the entirely new discipline of neutrino astronomy.

Scientists have detected a long-theorized but never-before-observed cosmic signal deep beneath the Antarctic ice, a breakthrough that could reshape our understanding of high-energy cosmic rays.
