Halley S Comet

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?

Pete de Lange must survive as a teenager in a small Natal town during the 1980s, together with his new-found friends, Sarita and Petrus. In a country marked by turmoil and racial conflict, this is not as easy as it seems. Pete and his friends witnessed a horrendous crime, and the perpetrator is on their case. Will justice prevail? In between all of this, Pete must try to make the first rugby team and win the heart of his high-school crush, Renate. This is an excellent Bildungsroman, full of emotion and nostalgia, set in a troubled country where doing the right thing was not always easy.

Provides information on the history of Halley's comet and the best places to view it as well as presenting folklore, a guide to astronomers, and a compendium of poetry and literature about comets

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.

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.

Describes the general characteristics of comets and gives a brief history of Halley's comet discussing its expected reappearance in late 1985-early 1986.
