El Cielo, las Estrellas Y La Noche/ The Sky, Stars, and the Night

Why is there day and night? Why does the Earth rotate on its axis and comes full circle in 24 hours? Why does the Sun only illuminate one side of the Earth at a time? Fascinating information about space and celestial bodies. It ends with a guide for observing the stars, biographical information on six preeminent astronomers, and poems by Lope de Vega and Jorge Luis Borges.
