Contribution grade

Astrophysics and cosmology · EMPIRICAL

Reference score240,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Seven balloon ascents showed a high-altitude increase in penetrating radiation, supporting incoming radiation from above.

Scientific scope

The record is Hess's sole-author 1912 paper and its balloon-flight evidence. It preserves Pacini and other antecedents and does not assign modern particle identities, mechanisms or the whole later field of cosmic-ray physics to this experiment.
