Book Description
The 1985/86 apparition of Halley's Comet turned out to be the most important apparition of a comet ever. It provided a worldwide science community with a wealth of exciting new discoveries, the most remarkable of which was undoubtedly the first image of a cometary nucleus. Halley's Comet is the brightest periodic comet, and the most famous of the 750 known comets. With its 76-year period, its recent appearance was truly a "once-in-a-lifetime" observational opportunity. The 1985/86 apparition was the thirtieth consecutive recorded apparition. Five apparitions ago, the English astronomer Edmond Halley discovered the periodicity of "his" comet and correctly predicted its return in 1758, a triumph for science best appreciated in the context of contemporary views, or rather fears, about comets at that time. The increasingly rapid progress in technological development is very much apparent when one compares the dominant tools for cometary research during Halley's next three apparitions: in 1835 studies were made based on drawings ofthe comet; in 1910 photographic plates were used; while in March 1986 an armada of six spacecraft from four space agencies approached the comet and carried out in situ measurements, 1 AU from the Earth. In 1910, nobody could have dreamed that this was possible, and today it is equally difficult to anticipate what scientists will be able to achieve in 2061.

Book Description
Returning to the Cavendish Laboratory in Cambridge after a spell at the nuclear research labs of CERN in Geneva, Professor Isaac Newton is plunged into the centre of a baffling mystery. One of his research students, Mike Howarth, has picked up strange signals on his satellite telemetry equipment, signals that appear to emanate from a passing comet. Not long after he has passed the vital data into Isaac Newton's hands, Howarth is found dead. Soon after that, it becomes clear that some people in very high places - including the Kremlin and the White House - are more than a little interested in the remarkable events taking place at the Cavendish. But with the arrival of that most majestic of all celestial bodies, Comet Halley, a third and infinitely more powerful superpower enters the scene. And the Comet's extraordinary intentions - not to mention its devastating methods of communicating them to Earth - promise a new dawn for humanity.

Book Description
Halley's Comet tells its own history in this unique STEM book Halley's Comet, visible from Earth only once every 75 years, tells its own story in this unique informational picture book. With each return of the comet, the book highlights human life at that time, and how science has advanced toward a greater understanding of our universe. Told in minimal, poetic text paired with detailed captions for context, the book begins with sightings in ancient civilizations, where for centuries, the comet was a mystery recorded in art and writing. From Edmond Halley's successful prediction of the comet's return in 1758, through the advent of technologies like cameras and eventually a spacecraft that photographed its ice core, Halley's Comet tells an inspiring and wide-reaching story of scientific advancement and cultural history. The book closes by inviting readers to wonder what our world might look like the next time Halley's Comet is visible from earth, expected in 2061. What will the comet "see," next time it passes by on its journey?

Book Description
What are these graceful visitors to our skies? We now know that they bring both life and death and teach us about our origins. Comet begins with a breathtaking journey through space astride a comet. Pulitzer Prize-winning astronomer Carl Sagan, author of Cosmos and Contact, and writer Ann Druyan explore the origin, nature, and future of comets, and the exotic myths and portents attached to them. The authors show how comets have spurred some of the great discoveries in the history of science and raise intriguing questions about these brilliant visitors from the interstellar dark. Were the fates of the dinosaurs and the origins of humans tied to the wanderings of a comet? Are comets the building blocks from which worlds are formed? Lavishly illustrated with photographs and specially commissioned full-color paintings, Comet is an enthralling adventure, indispensable for anyone who has ever gazed up at the heavens and wondered why. Praise for Comet "Simply the best." —The Times of London "Fascinating, evocative, inspiring." —The Washington Post "Comet humanizes science. A beautiful, interesting book." —United Press International "Masterful . . . science, poetry, and imagination." —The Atlanta Journal & Constitution

Book Description
Sky & Telescope has produced [this booklet] for inexpensive mass distribution, especially to young people. It's meant to be the public's foolproof guide to finding the comet on any date it can be seen at all. The instructions require no knowledge of astronomy and avoid such words as "altitude" and "azimuth", but will enable anyone to locate the coment fairly accurately."--Undated letter from Alan MacRobert, Sky Publishing Corporation (stapled to back cover of LHL copy.)
