In Neil de Grasse Tyson’s delightful tour of the galaxies, his fictional character Merlin responds to popular astronomy questions asked by adults and children alike. Merlin, a visitor from Planet Omniscia in the Andromeda Galaxy, has been friends with many of the most important scientific figures of the past, including da Vinci, Magellan, Doppler, Einstein, and Hubble—and he often recounts his conversations with these historical figures in his explanations. Merlin’s illuminating answers feature a unique combination of wit and poetry along with serious science explained in refreshingly clear, reader-friendly language.
