Internationella geofysiska året

Officiellt emblem med text på franska och engelska.

Internationella geofysiska året var ett internationellt naturvetenskapssamarbete under perioden 1 juli 1957-31 december 1958, då man upplevde att spänningen i världspolitiken minskat sedan Josef Stalins död 1953. Både Sovjet och USA skickade iväg sina första satelliter i samband med detta, och Van Allen-bältena upptäcktes. Dessutom gjordes framsteg i utvecklandet av teorin om plattektonik-teorin om kontinentaldriften.[1]
