ZH_5_10 — Naked-Eye Observational Limits: Precision, Techniques, and Ancient Achievement

For all but the last ~400 years of human history, every astronomical observation was made with the unaided eye. Understanding the limits and capabilities of naked-eye observation is therefore essential for evaluating anc

ZH_1_10 — Transit of Venus: Political Astronomy and Global Science

A transit of Venus — when the planet Venus crosses the disk of the Sun as seen from Earth — is among the rarest of predictable astronomical events, occurring in a pattern of pairs separated by ~8 years, with the pairs se

Q_2_07 — Cosmic Distance Ladder: Measuring the Universe

The cosmic distance ladder is a succession of techniques by which astronomers measure distances from nearby stars to the edge of the observable universe — each rung calibrates the next. Trigonometric parallax (reliable t
