1985-85 Heralds the Return of Nature's Most Spectacular Sky Show!

The last time Halley's Comet flashed through the night sky was in 1910. Now it's coming again--to send shivers of delight and fear through all on Earth. Scientists around the world are preparing for the biggest coordinated space effort ever undertaken to study a celestial object, but the dazzling cosmic visitor with its breathtaking size and brilliant tail will be easily observed from Earth even without a telescope. It will be a memory to treasure and tell children and grandchildren about for decades to come.

Now, Science Digest brings you this easy-to-read, authoritative souvenir guide book filled with fascinating facts about the famous comet that makes an appearance only every 75 years. It explains what comets are, how they differ from each other and other heavenly bodies, and their colorful roles in Earth's history as harbingers of mystical calamities and real catastrophes, as well as battles royal among the world's scientists.
