Containing star charts, a guide to the constellations, and details about seasons and the movement of the objects we see in the sky, this classic book makes H. A. Rey's passion for astronomy evident on every page. New updates concentrate on the planetary and solar system information in the latter part of the book. Facts and figures for each planet have been revised, and new scientific information has been added, such as Pluto's reclassification as a dwarf planet. There's also a new online resource that allows readers to track the positions of the planets in the night sky till the year 2100.

More of Isaac Asimov's weekly science columns for the Los Angeles Times and those his wife, Janet, wrote during his illness and after his death in April 1992. The Asimovs discuss how close we are to producing life in a lab, the latest revelations about dinosaur extinction, recent startling sightings of planets and stars, if we can establish colonies on Mars, if computer intelligence can ever surpass human intelligence, and the gravest dangers to our environment.
