Auroræ: Their Characters and Spectra

The Northern Lights have fascinated travelers and scientists for centuries, and this volume offers a clear, engaging tour of their many forms. Drawing on reports from Arctic explorers, early spectroscopic studies, and vivid eyewitness accounts, the author guides listeners through the shifting curtains of green, red, and violet that paint the night sky. Readers will learn why these luminous dances have inspired poetry, myth, and a steady stream of scientific inquiry.

The book also delves into the lingering mystery of the auroral spectrum, explaining how bright red and green lines still defy easy identification. Hands‑on experiments, described in vivid detail, show how magnetic fields influence electric discharges, bringing the science to life for the curious ear. Accompanied by richly colored plates and original sketches, the narrative balances historical anecdotes with modern insight, inviting anyone with a wonder for the night sky to look upward and observe.
