The Losers at the Center of the Galaxy


Book Description

A tuba player without a tuba and his jellyfish-imitating sister cope with their father's disappearance in a middle-grade novel both hilarious and moving by Mary Winn Heider, the author of The Mortification of Fovea Munson. Now in paperback! When Lenny Volpe, former quarterback of the worst professional football team in the nation, leaves his family and disappears, the Chicago Horribles win their first game in a long time. Fans are thrilled. The world seems to go back to normal. Except for the Volpe kids. Winston throws himself into playing the tuba, and Louise starts secret experiments to find a cure for brain injuries, and they're each fine, just fine, coping in their own way. That is, until the investigation of some eccentric teacher behavior and the discovery of a real live bear paraded as the Horribles' new mascot make it clear that things are very much Not Fine. The siblings may just need each other, after all.




The Center of the Galaxy


Book Description

The investigation of the Galactic nucleus and its surroundings is necessarily a modem endeavor, for traditional observations made at visual wavelengths have not even begun to penetrate the veil of -30 magnitudes of visual extinction that intercedes. On the other hand, infrared, and especially radio observers find a relatively unobstructed view of the central portion of the Galaxy, so the study of this arena has proceeded apace with the development of these branches of astronomy. Thus, it is no accident that the first IAU sponsored conference to be held on the Galactic center is timed to coincide with the initiation, or the immediate aftennath, of major technical developments at long wavelengths, including infrared array detectors, millimeter-wavelength aperture synthesis, and self-calibration and refmed deconvolution algorithms in aperture synthesis radio astronomy. The center of the Galaxy is also accessible to X and gamma-ray observers, and progress at high energies has been steady, especially as imaging capabilities are being realized at X-ray wavelengths. However, one might expect that the revolution in the high energy domain is still ahead of us, as instruments with larger collecting areas and improved spatial resolution are now being developed. The youth of this subject is evidenced by the relatively small number of meetings that have been devoted to it.







Furious Gulf


Book Description

The Nebula Award-winning author's fifth installment of his classic Galactic Center series is reissued in this special edition that contains a teaser chapter from The Sunborn. Trying to escape the relentless mechs, the last humans from planet Snowglade take their ancient starship on a dangerous course straight into the Eater, the black hole at the galactic center. Hungry and desperate, the refugees begin to question the leadership of Captain Killeen, who believes the center holds their one hope of survival. Meanwhile, Killeen's son Toby struggles with the microchips that were implanted in his spine-a technology that now threatens his sanity. Caught between their genocidal pursuers and peril in the galactic center, Killeen and Toby bring humanity to its final destiny.

Great Sky River


Book Description

The third novel in the award-winning author's classic Galactic Center series is available once again. "A challenging, pacesetting work of hard science fiction that should not be missed" (Los Angeles Times). Nearly 100,000 years after first contact with the machines that dominate the universe, a few hundred humans survive. Trapped on Snowglade, a barren world near the center of the galaxy, people like Killeen of Family Bishop and his child Toby are primitive scavengers, homeless and hunted by the ruling "mechs." Then suddenly, a strange cosmic entity-neither organic nor cybernetic nor living matter-reaches out from a black hole to speak with Killeen. But can this fallen descendant of starfarers understand this alien being in time-and seize his only chance to save his family and mankind from final annihilation?




The Black Hole at the Center of the Milky Way


Book Description

Reviewing the fundamental instrumental techniques and current observational results, this book unveils the mysteries of the physical processes in the central parsec of our Milky Way: the super-massive black hole embedded in a central stellar cluster as well as the gas and dust in the circumnuclear region. The observations described cover the entire electromagnetic spectrum from decimeter radio-waves to high energy X-ray and ?-rays, and a comprehensive summary of up-to-date astrophysical interpretations is given. The emphasis is put on observational techniques, image processing aspects, and a detailed presentation of the most cutting-edge work carried out in the near-infrared wavelength regime. These recent results include both the first orbits of stars around the central black hole and the multiwavelength variability of the central source.




Comets


Book Description

Radiating fire and ice, comets as a phenomenon seem part science, part myth. Two thousand years ago when a comet shot across the night sky, it convinced the Romans that Julius Caesar was a god. In 1066, Halley’s Comet was interpreted as a foreshadowing of the death of Harold the Second in the Battle of Hastings. Even today the arrival of a comet often feels auspicious, confirming our hopes, fears, and sense of wonder in the universe. In Comets, P. Andrew Karam takes the reader on a far-ranging exploration of these most beautiful and dramatic objects in the skies, revealing how comets and humanity have been interwoven throughout history. He delves into the science of comets and how it has changed over time; the way comets have been depicted in art, religion, literature, and popular culture; and how comets have appeared in the heavens through the centuries. Comprehensive in scope and beautifully illustrated throughout, the book will appeal not only to the budding astronomer, but to anyone with an appreciation for these compelling and remarkable celestial bodies.




Discovery of Our Galaxy


Book Description

This is a book about the mystery and the passion, the imagination, religion, and poetry, the philosophy, the intellectual flights—and, above all, the people—that have created the science of astronomy, from Thales of Miletus predicting eclipses in the sixth century B.C. to today’s scientists probing the cosmic significance of the mysterious “black holes” discovered in 1970. With authority and charm, the distinguished Harvard astronomer Charles A. Whitney here re-creates the lives and temperaments of the great astronomers and retraces the ingenious arguments, the feats of observation and deduction, and the leaps of intuition by which they have gradually unveiled a picture of the universe and have brought us to an understanding of our own planet’s place in it. Among them: KEPLER, searching the solar system for visible evidence of the transcendent order he believed in GALILEO, constructing the first telescope and proposing the concept of universal gravitation NEWTON, paragon of logic, paradoxically driven by an unshakable belief in himself as God’s appointed prophet to create a world of mathematical certainty and thus expose the wonder of his Father in Heaven WILLIAM HERSCHEL, the nineteenth-century German who may well be considered the father of modern astronomy, first man to chart the nebulae EDWIN HUBBLE, in the present century, discovering and exploring galaxies beyond our own Finally, Professor Whitney makes clear for the layman the fascinating problems astronomers wrestle with today: the mysterious nature of quasars, strange cosmic bodies discovered in 1963; the unknown forces behind cataclysmic explosions recently glimpsed in other galaxies; the elusive nature of “interstellar dust”; the eternal question of how it all began.
