The formation of the first stars (Pop III stars) and galaxies is one of the great outstanding challenges in modern astrophysics and cosmology. The first stars are likely key drivers for early cosmic evolution and will be at the center of attention over the next decade. The best available space and ground-based telescopes like the Hubble Space Telescope probe the Universe to high redshifts and provide us with tantalizing hints; but they cannot yet directly detect the first generation of stars and the formation of the first galaxies. This is left as key science for future telecopes like the James Webb Space Telescope. This book is based in part on classroom tested lectures related to Pop III stars, but also draws from the author's review articles of the main physical principles involved. The book will thus combine pedagogical introductory chapters with more advanced ones to survey the cutting-edge advances from the frontier of research. It covers the theory of first star formation, the relation between first stars and dark matter, their impact on cosmology, their observational signatures, the transition to normal star formation as well as the assembly of the first galaxies. It will prepare students for interpreting observational findings and their cosmological implications.

Noah can’t wait to go home. He doesn’t fit in and his family won’t miss him. He never dreamed he would end up living in a nightmare. Who can he trust? The pirates who take him in, his protector who abandoned him, or is he just bait in an elaborate trap? The First Star continues the story of the Fraser family caught between worlds, hunted by aliens, and holding the key to the survival of Earth.

Presents a brief introduction to star lore in Native American beliefs and culture; describes and provides illustrations of classical Greek constellations; and features information about the cultures and star lore of various Native American tribes, organized by culture area.

A Star Trek adventure set during The Original Series era and featuring James T. Kirk and the U.S.S. Enterprise crew! While testing a new shielding device, the U.S.S. EnterpriseTM is caught in the middle of a Klingon/Romulan battle. The Enterprise crew rescues a lifepod, and they are confronted by a Klingon who claims to know nothing of human existence. Convinced the Klingon is telling the truth, Captain Kirk hurries to Starfleet Headquarters in search of answers. But upon arriving on Earth, the Starship Enterprise crew finds that Earth is a vast jungle-like paradise where large, reptillian animals rule, with no signs of human life anywhere. Kirk must travel to the past in search of the key to the mystery, or face the destruction of the human race.

This book takes readers on a fantastic voyage to the physics of eternity, with a long-term projection of the evolution of the universe.

On a windy spring day, Bear sniffs the air. Could it be. . . Kite day? Rushing home he tells Mole, and the two fast friends get to work building a kite of their own. They study, and collect, and measure, and construct—and soon, their kite is flying high above the meadow. But when a storm rumbles in—SNAP!—the kite string breaks, and all their hard work soars away. Chasing after it, Mole and Bear discover all is not lost—wedged in the branches of a tree, their kite protects a nest of baby birds from the pouring rain. Will Hillenbrand's Bear and Mole series is the perfect choice for storytime sharing or reading aloud. Strong verbs, repetitive phrases, and fun-to-read sounds keep young listeners and readers engaged with the story, while the gentle illustrations add detail and quiet humor. Kids will delight in poring over these books again and again. Don't miss the other Bear and Mole titles, including All For a Dime, Spring is Here, and First Star!
