Download or read book Unidentified written by Robert Salas and published by Career Press. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1969 the U.S. Air Force issued a statement that read' "No UFO reported, investigated and evaluated by the Air Force was ever an indication of threat to our national security." This statement is patently false. It has been proven untrue by the testimony of many military officers and airmen and documentation of incidents involving UFOs and nuclear weapons, testimonies of which the U.S. Air Force was fully aware. Unidentified details many of these testimonies, some for the first time. As partial justification for its position, the Air Force cites a University of Colorado study that was contracted and paid for by federal funds. Unidentified reveals how this study was actually just another part of the plan to cover up the reality of the UFO phenomenon. For the first time, Unidentified publishes evidence that the investigators for the Colorado study knew about the UFO-related missile shutdown incidents but did not investigate them or include them in their final report.

Book excerpt: An Apollo 11 astronaut and the Nebula Award–nominated author of Directive 51 present a novel that “conveys the wonder and promise of space” (Publishers Weekly). Born the year of the Moon landing, Chris Terence spends his life fighting to return humanity to that pinnacle. An engineering student with dreams of spaceflight, he finds upon graduation that the United States no longer has need for astronauts. Years of bureaucratic meddling have reduced the space program to a shell of itself, and it will take the greatest scientific find in history to send humanity skyward once more. After years battling budget hawks, Chris finally gets his chance to walk on the Moon. While there, he finds evidence of an ancient alien civilization, the Tiberians, who visited Earth’s satellite eight thousand years before. Understanding what happened to those long-forgotten travelers will define the lives of Chris and his son, as they fight against all odds to unlock the secrets of the universe. “The collaboration of the first man to pilot a moon lander (Aldrin) with a major voice in contemporary science fiction (Barnes) has produced a fascinating chronicle of man’s first encounter with alien intelligence” (Booklist).

Book Synopsis Spiral Structure in Galaxies by : Marc S Seigar
Download or read book Spiral Structure in Galaxies written by Marc S Seigar and published by Morgan & Claypool Publishers. This book was released on 2017-06-29 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: How does it happen that billions of stars can cooperate to produce the beautiful spirals that characterize so many galaxies, including ours? This book reviews the history behind the discovery of spiral galaxies and the problems faced when trying to explain the existence of spiral structure within them. In the book, subjects such as galaxy morphology and structure are addressed as well as several models for spiral structure. The evidence in favor or against these models is discussed. The book ends by discussing how spiral structure can be used as a proxy for other properties of spiral galaxies, such as their dark matter content and their central supermassive black hole masses, and why this is important.

Download or read book The Origin of Galaxies written by Jin He and published by AuthorHouse. This book was released on 2009-11-24 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why is there no dust in elliptical galaxies? Firstly, the universe is rational and the rationality is proportion at large scale systems such as galaxies. Proportion means that the distribution of matters in the universe is orderly. For example, there are four giants standing in array. Their heights are respectively A, B, C, D, and A, B stand in the first row from left to right, C, D in the second row from left to right. Proportion requires that A divided by C be equal to B divided by D. Rational structures are either circularly symmetric with respect to the center point, or bilaterally symmetric. Secondly, spiral galaxy arms are neither circularly symmetric nor bilaterally symmetric. Therefore, arms are not rational structure. Arm patterns exist only in spiral galaxies and they are weak compared with the main disk structure of spiral galaxies. Therefore, the presence of arm structure is the disturbance to the rational structure. Because arm patterns exist only in spiral galaxies and only spiral galaxies present dust, Dr. He comes to the critical answer to the above question: any disturbance to rational structure produces cosmic dust! From now on we call the disturbance to rational structure the cosmic impulse. Therefore, the universe is originated not only rationally but also impulsively!
