G_1_18 — Acoustic Archaeology & Archaeoacoustics

Acoustic archaeology (archaeoacoustics) is the study of sound in past environments and the acoustic properties of archaeological sites, monuments, and artifacts. Emerging as a formal subdiscipline in the 1990s through th

O_1_02 — Magnetosphere, Solar Activity, and Earth's Shield

Earth's magnetic field is an invisible shield that makes complex life on the surface possible — without it, solar wind would strip away the atmosphere and sterilize the planet, as happened to Mars ~3.8 billion years ago
