What happens when a star dies? How many asteroids are in our solar system? What is dark energy? From Trojan asteroids to stellar black holes, from superclusters to cosmic background microwave radiation, this chunky little introduction to astronomy takes readers on an entertaining tour around the universe. It begins with the specks and constellations that we see in the night sky, then zooms in on the objects and matter beyond the naked eye. In concise, two-page entries, the book explains these astronomical topics in a way that makes them easy to understand, illustrated with black and white photos, drawings, or diagrams.
