О планетах и галактической обитаемой зоне
Литература, Наука, Писателям Комментариев: 2 »Продолжая серьезную тематику блога, предлагаю вниманию читателя несколько интересных книг и документов на тему пригодных для обитания человека планет и места в галактике, пригодного для таких планет.
Предыдущий пост по теме здесь.
В этот раз литература на английском языке. Итак, начнем.
#1
On the “Galactic Habitable Zone” , author: Nikos Prantzos (Institut d’Astrophysique de Paris), 12 Dec 2006.
” The concept of Galactic Habitable Zone (GHZ) was introduced a few years ago as an extension of the much older concept of Circumstellar Habitable Zone. However, the physical processes underlying the former concept are hard to identify and even harder to quantify. That difficulty does not allow us, at present, to draw any significant conclusions about the extent of the GHZ: it may well be that the entire Milky Way disk is suitable for complex life”.

Charles H. Lineweaver, Yeshe Fenner, Brad K. Gibson, The Galactic Habitable Zone and the Age Distribution of Complex Life in the Milky Way
“We modeled the evolution of the Milky Way to trace the distribution in space and time of four prerequisites for complex life: the presence of a host star, enough heavy elements to form terrestrial planets, sufficient time for biological evolution and an environment free of life-extinguishing supernovae. We identified the Galactic habitable zone (GHZ) as an annular region between 7 and 9 kiloparsecs from the Galactic center that widens with time and is composed of stars that formed between 8 and 4 billion years ago. This GHZ yields an age distribution for the complex life that may inhabit our Galaxy. We found that 75% of the stars in the GHZ are older than the Sun.”

Habitable Planets for Man (originally published in 1964) by Stephan H. Dole.
Habitable Planets for Man examines and estimates the probabilities of finding planets habitable to human beings, where they might be found, and the number there may be in our own galaxy. The author presents in detail the characteristics of a planet that can provide an acceptable environment for humankind, itemizes the stars nearest the earth most likely to possess habitable planets, and discusses how to search for habitable planets. Interestingly for our time, he also gives an appraisal of the earth as a planet and describes how its habitability would be changed if some of its basic properties were altered. Habitable Planets for Man was published at the height of the space race, a few years before the first moon landing, when it was assumed that in the not-too-distant future human beings “will be able to travel the vast distances to other stars.”
Несмотря на то, что книга написана очень давно, она все еще актуальна.

Geology Habitability of Terrestrial Planets, reprinted from Space Science Reviews Volume 129, Issues 1–3, 2007. A collection of papers. Editors: Kathryn E. Fishbaugh, David J. Des Marais, Oleg Korablev, Philippe Lognonné and François Raulin.
“This book has arisen from a unique workshop, entitled “Geology and Habitability of Terrestrial Planets”, held at the International Space Science Institute (ISSI) in Bern, Switzerland, on 5–9 September 2005. The goal of this workshop, as articulated by the conveners, was “to define the influence of planetary geologic evolution on habitability and to assess the conditions necessary for life, using the Earth, Mars, and Venus as examples.” The intent was to focus on the relationship between a planet’s origin and evolution and its capacity to sustain habitable environments”.

WorldWide Telescope (WWT)
Acta Astronautica publishes original contributions in all fields of basic, engineering, life and social space sciences and of space technology related to: the peaceful scientific exploration of space, its exploitation for human welfare and progress and the conception, design, development and operation of space-borne and Earth-based systems. In addition to regular issues of contributed papers, the journal publishes selected proceedings of the annual International Astronautical Congress (IAC), transactions of the IAA and special issues on topics of current interest, such as microgravity, space station technology, geostationary orbits, and space economics. Other major subject areas regularly covered include satellite technology, space transportation and communications, space energy, power and propulsion, astrodynamics, extraterrestrial intelligence and Earth observations.
