From the Nebula Award-winning author comes a newly revised edition of this story in his classic Galactic Center series. 2076: Technology has propelled the world into a new age of enlightenment. Nigel (from In the Ocean of Night) has left Earth to explore space for alien life. But while on this captivating mission, humanity's birthplace has fallen prey to attack and its seas are seeded with alien lifeforms. Now, Nigel is left to search for the only savior he knows-the one who saved him once before-the alien machine called the "Snark." Having left the solar system and turned traitor to its alien masters, Nigel is unsure of the Snark's new allegiance. Is the Snark a friend? Or will it also turn on Nigel... proving to be a deadly foe?

An introduction to the Milky Way galaxy.

Our Galactic center's proximity allows astronomers to study physical pro cesses within galactic nuclei at a level of detail that will never be possible in the more distant, but usually also more spectacular, extragalactic systems. Recent advances in instrumentation from the radio, through the submillime ter and infrared wavebands, and out to the X- and "'(-ray bands now allow observations of the Galactic Center over thirteen orders of magnitude in wave length. Our knowledge about the central few hundred parsecs of our Galaxy has consequently increased vastly over the past decade. The same new instru ments provide high resolution, high quality measurements of nearby ''normal'' galactic nuclei; that is, nuclei whose modest energy output is comparable to that of our own (and most other) galaxies. Theorists, spurred in part by the new observations, have been able to refine models of the energetics, dynam ics, and evolution of the gas and stellar systems deep within galactic nuclei.

This new, special edition of the classic concluding volume of this defining series by the eminent physicist and Nebula Award-winning author contains a teaser chapter from Benford's, The Sunborn. The final chapter of humanity's future has begun, and three men hold the key to survival. As the fierce, artificially intelligent mechs pursue their savage and unstoppable destruction of the human race, it soon becomes apparent that three men-three generations in a family of voyagers-are their targets. Toby Bishop, his father Kileen, and his longdead grandfather each carry a piece of the lethal secret that can destroy their relentless pursuers. There is only one problem: They have no idea they possess the only weapon that can save humanity.

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.

This book provides a comprehensive, self-contained introduction to one of the most exciting frontiers in astrophysics today: the quest to understand how the oldest and most distant galaxies in our universe first formed. Until now, most research on this question has been theoretical, but the next few years will bring about a new generation of large telescopes that promise to supply a flood of data about the infant universe during its first billion years after the big bang. This book bridges the gap between theory and observation. It is an invaluable reference for students and researchers on early galaxies. The First Galaxies in the Universe starts from basic physical principles before moving on to more advanced material. Topics include the gravitational growth of structure, the intergalactic medium, the formation and evolution of the first stars and black holes, feedback and galaxy evolution, reionization, 21-cm cosmology, and more. Provides a comprehensive introduction to this exciting frontier in astrophysics Begins from first principles Covers advanced topics such as the first stars and 21-cm cosmology Prepares students for research using the next generation of large telescopes Discusses many open questions to be explored in the coming decade

A guide to the expansion of consciousness possible during the Galactic Alignment of 2012 • Reveals the new era that will be ushered in as the current perception of time collapses and spiritual perception expands • Explains the psycho-spiritual preparations necessary to transition into this new era • Shows how the alignment of the sun with the Galactic Center will allow humans to experience awareness normally reserved for shamans, pharaohs, and sages This is an extraordinary time in the planet’s history. In 2012, for the first time in almost 26,000 years, our sun will be most closely aligned to the Galactic Center. This Galactic Alignment, which began with the Harmonic Convergence in 1987 and will conclude in 2023, presents a thirty-six-year window of opportunity for humanity to participate in the creation of a new era of expanded consciousness. Christine Page explains that, as the source of all creation, our galaxy is the Great Mother and its center, her heart. Auspiciously aligning Earth with the heart of the Great Mother, the Galactic Alignment heralds a rebirth of the divine feminine qualities of the Triple Goddess--intuition, emotional creativity, and renewal. Drawing on alchemy and mythology, Page details how to connect with and use the sacred spiritual tools unlocked during the alignment to merge with the Great Mother, a spiritual transformation that allows us to expand our awareness and experience ourselves as eternal beings.
