Kurzbeschreibung des Verlags

COSMIC ARCHAEOLOGY:How to Read the Universe's PastBook 2Series "In Twelve Evenings"Vita HarwoodEvery telescope looks into the past. Moonlight reaches us a little more than a second after leaving the lunar surface, sunlight takes about eight minutes, and light from distant galaxies can travel for millions or billions of years. But how do astronomers turn ancient light into reliable evidence about what happened long before humans existed?Cosmic Archaeology: How to Read the Universe's Past is a twelve-lesson short course for readers aged 15 and up, and for adults who want to understand astronomy and cosmology without university-level mathematics. Instead of presenting a list of cosmic records, the book follows the logic of a scientific investigation: What evidence reached us? What was actually measured? What can we infer from it? What still remains unknown?Step by step, readers learn why a telescope shows the past, how astronomers measure immense distances, what a spectrum reveals about a star, how redshift connects observation with the history of an expanding Universe, why chemical composition preserves traces of earlier generations of stars, and what the cosmic microwave background tells us about the oldest electromagnetic light we can observe. Later lessons explore the first stars and galaxies, galactic archaeology inside the Milky Way, stellar remnants, and gravitational waves.Every lesson includes a scientist portrait, a verified surprising fact, key terms, a ten-question test, and an at-home experiment or small data exercise. The book concludes with explanations for all 120 test questions, a course glossary, lesson-by-lesson resources, and suggestions for what to read and watch next.This is a book about learning to read cosmic history from evidence that has survived the journey through space and time.
