An innovative and visually sweeping picture book imagines Halley's Comet observing Earth and its inhabitants at every pass, tracing human evolution over millennia. First recorded traveling overhead in 240 BCE, Halley's Comet returns every seventy-six years or so for a fresh glimpse of life on bountiful Earth. In a wondrous story told from the comet's point of view, the creator of A Green Place to Be weaves scenes of Halley's hurtling through space with views of Earth and its evolving flora and fauna below. Even as humans gaze up in search of the celestial wanderer--tracking the "broom star" in words and pictures--the comet gazes down, forming gentle conclusions. Each visit reveals how curious and creative humans transform the planet, contributing war and pollution but also a boundless capacity to love. What will the comet find when it passes again in 2061? Time stamps and thorough back matter ground a lyrical and luminously illustrated story in sound historical and scientific research. A kaleidoscope of biodiversity, locales, and peoples, Cosmic Wonder gracefully charts the highs and lows of human civilization through the eyes of a sympathetic watcher.
