One day not too far from now there will be too many people on this planet. When that day comes, what will we do? Jerry, Michael, Emily, Amelia, Abigail and David receive their answer in the form of a letter. Proxima B is waiting for them and is going to expose their differences and their fears, which will let them make unexpected choices. Sometimes, a more obvious answer is not more predictable. Co-authored science fiction novel about a space mission that leads a group of colonists to land on Proxima b, which is an exoplanet in the habitable zone of the red dwarf called Proxima Centauri and whose distance from the sun is 4.24 light years. The year is 2099. Due to world's pollution, the excessive number of inhabitants, the subsequent lack of resources and other reasons, Earth is no longer fit to live in. The only hope is to try to reach what appears to be a ”second possibility”, Proxima b, indeed. This is why New Nasa Corporated is planning a mission called ”For everyone's sake!” that imposes the recruitment of several practitioners in their own field, including biologists, doctors, chemists, engineers and soldiers. These include Jerry, Michael, Emily, Amelia, Abigail and David, in addition to Matthew Ross, who is the captain of one of the three mother ships (the MATERs) that after the ”new colonizers” have been trained leave Earth and manage to reach the new planet through a wormhole. But during space travel something does not go as planned. Terrestrial beings find something different from what they expected on Proxima...

In the safety of their dome, the colonists on Proxima B would create a perfect society-at least that was the plan designed by SECA, the Space Exploration and Colonization Administration. The scientists and administrators at SECA had carefully arranged everything: the dome that could accommodate the colony as it grew, the selection of the two hundred young men and women chosen for their diverse areas of expertise, and of course the technology that would allow the people of Earth to view the "colony experience" as the colonists became acquainted with each other and their new world. The viewing public could hardly wait for this. That was the plan, but unknown to everyone, the frozen planet was home to forces that would disrupt this plan and require the colonists to face physical and emotional tests that they never expected.

Time is running out for the inhabitants of Proxima Centauri. Unsettling discoveries there and at Luyten’s star now threaten both Proxima and Earth, in a new hard science fiction thriller from Travis S. Taylor and Les Johnson. First contact with the seemingly impossible human civilization at Proxima Centauri is not going well. The Earth ships sent to render aid have not been able to reverse the contagion ravaging their population and, worse, many Proximans are now wondering if the humans from Earth are there for other, not so charitable, reasons. Can the extinction-level disaster faced at Proxima be reversed by the combined ingenuity of scientists from both worlds working together? Unsettling discoveries in the Proxima Centauri planetary system beg the questions: What if the evil gods depicted in Proxima’s ancient mythologies were real and far more powerful than even the humans from Earth with their late 21st century technologies? Worse, what if their ancient oppressors never truly left? At the publisher's request, this title is sold without DRM (Digital Rights Management). Praise for Travis S. Taylor: “. . . explodes with inventive action.” —Publishers Weekly on Travis S. Taylor’s The Quantum Connection “[Warp Speed] reads like Doc Smith writing Robert Ludlum . . . You won’t want to put it down.” —John Ringo Praise for Stellaris: People of the Stars, coedited by Les Johnson: “. . . a thought-provoking look at a selection of real-world challenges and speculative fiction solutions. . . . Readers will enjoy this collection that is as educational as it is entertaining.” —Booklist “This was an enjoyable collection of science fiction dealing with colonizing the stars. In the collection were several gems and the overall quality was high.” —Tangent Praise for Mission to Methone by Les Johnson: “The spirit of Arthur C. Clarke and his contemporaries is alive and well in Johnson’s old-fashioned first-contact novel, set in 2068. . . . includes plenty of realistic detail and puts fun new spins on familiar alien concepts. . . . There’s a great deal here for fans of early hard SF.” —Publishers Weekly “With equal parts science fiction and international intrigue. . . . an exciting, fast-paced read that you will not want to put down.” —Booklist Praise for Rescue Mode by Ben Bova and Les Johnson: “. . . a suspenseful and compelling narrative of the first human spaceflight to Mars.” —Booklist

This thought-provoking book looks at the nature of red dwarf systems as potential homes for life. Realistically, what are the prospects for life on these distant worlds? Could life evolve and survive there? How do these planetary surfaces and geologies evolve? How would life on a planet orbiting a red dwarf differ from life on Earth? And what are the implications for finding further habitable worlds in our galaxy? The author provides readers with insight into the habitability of planets and how this changes as time progresses and the central star evolves. Since the previous 2013 edition Under a Crimson Sun, there has been a rise in newly discovered planets orbiting red dwarfs, accompanied by controversial areas of research that test what we think we know about these systems. This revised edition delves into the wealth of new material uncovered since that date. It explains the often conflicting results and analyses put forward and clarifies our understanding of these exciting new worlds. The chapters explore the full width of relevant scientific discovery and speculation on the potential for red dwarf planets to host life. New content includes improved atmospheric models, new understandings of the impact of stellar radiation on the atmosphere of red dwarf worlds, tidal-locking, and comparisons with terrestrial geology and climate.

An in-depth view of the panspermia hypothesis examined against the latest knowledge of planetary formation and related processes. Panspermia is the concept that life can be passively transported through space on various bodies and seed, habitable planets and moons, which we are beginning to learn may exist in large numbers. It is an old idea, but not popular with those who prefer that life on Earth started on Earth, an alternative, also unproven hypothesis. This book updates the concept of panspermia in the light of new evidence on planet formation, molecular clouds, solar system motions, supernovae ejection mechanisms, etc. Thus, it is to be a book about newly understood prospects for the movement of life through space. The novel approach presented in this book gives new insights into the panspermia theory and its connection with planetary formation and the evolution of galaxies. This offers a good starting point for future research proposals about exolife and a better perspective for empirical scrutiny of panspermia theory. Also, the key to understanding life in the universe is to understand that the planetary formation process is convolved with the evolution of stellar systems in their galactic environment. The book provides the synthesis of all these elements and gives the readers an up-to-date insight on how panspermia might fit into the big picture. Audience Given the intrinsic interdisciplinary nature of the panspermia hypothesis the book will have a wide audience across various scientific disciplines covering astronomy, biology, physics and chemistry. Apart from scientists, the book will appeal to engineers who are involved in planning and realization of future space missions.

Astrobiology not only investigates how early life took hold of our planet but also life on other planets – both in our Solar System and beyond – and their potential for habitability. The book take readers from the scars on planetary surfaces made by space rocks to the history of the Solar System narrated by those space rocks as well as exoplanets in other planetary systems. But the true question is how life arose here or elsewhere. Modern comparative genomics has revealed that Darwin was correct; a set of highly conserved genes and cellular functions indicate that all life is related by common ancestry. The Last Universal Common Ancestor or LUCA sits at the base of the Tree of Life. However, once that life took hold, it started to diversify and form complex microbial communities that are known as microbial mats and stromatolites. Due to their long evolutionary history and abundance on modern Earth, research on the biological, chemical and geological processes of stromatolite formation has provided important insights into the field of astrobiology. Many of these microbialite-containing ecosystems have been used as models for astrobiology, and NASA mission analogs including Shark Bay, Pavilion and Kelly Lakes. Modern microbialites represent natural laboratories to study primordial ecosystems and provide proxies for how life could evolve on other planets. However, few viral metagenomic studies (i.e., viromes) have been conducted in microbialites, which are not only an important part of the community but also mirror its biodiversity. This book focuses on particularly interesting sites such as Andean lake microbialites, a proxy of early life since they are characterized by very high UV light, while Alchichica and Bacalar lakes are characterized by high-salt and oligotrophic waters that nurture stromatolites. However, it is only the oasis of Cuatro Ciénegas Basin in México that stored past life in its marine sediments of the Sierra de San Marcos. This particular Sierra has a magmatic pouch that moves the deep aquifer to the surface in a cycle of sun drenched life and back to the depths of the magmatic life in an ancient cycle that now is broken by the overexploitation of the surface water as well as the deep aquifer in order to irrigate alfalfa in the desert. The anthropocene, the era of human folly, is killing this unique time machine and with it the memory of the planet.

Like planets in our solar system, exoplanets form, evolve, and interact with their host stars in many ways. As exoplanets acquire material and grow to the final size, their atmospheres are subjected to intense UV and X-radiation and high-energy particle bombardment from the young host star. Whether a planet can retain its atmosphere and the conditions for significant mass loss both depend upon the strength of the host star's high-energy radiation and wind, the distance of the exoplanet from its host star, the gravitational potential of the exoplanet, and the initial chemical composition of the exoplanet atmosphere. This introductory overview describes the physical processes responsible for the emission of radiation and acceleration of winds of host stars that together control the environment of an exoplanet, focusing on topics that are critically important for understanding exoplanetary atmospheres but are usually not posed from the perspective of host stars. Accordingly, both host stars and exoplanets are not studied in isolation but are treated as integrated systems. Stellar magnetic fields, which are the energy source for activity phenomena including high-energy radiation and winds, play a critical role in determining whether exoplanets are habitable. This text is primarily for researchers and graduate students who are studying exoplanet atmospheres and habitability, but who may not have a background in the physics and phenomenology of host stars that provide the environment in which exoplanets evolve. It provides a comprehensive overview of this broad topic rather than going deeply into many technical aspects but includes a large list of references to guide those interested in pursuing these questions. Nonspecialists with a scientific background should also find this text a valuable resource for understanding the critical issues of contemporary exoplanet research.

How would you survive on a planet that doesn't spin? An awe-inspiring Planetary Romance from Terry Pratchett's co-author on the Long Earth Books The very far future: The Galaxy is a drifting wreck of black holes, neutron stars, chill white dwarfs. The age of star formation is long past. Yet there is life here, feeding off the energies of the stellar remnants, and there is mind, a tremendous Galaxy-spanning intelligence each of whose thoughts lasts a hundred thousand years. And this mind cradles memories of a long-gone age when a more compact universe was full of light ... The 27th century: Proxima Centauri, an undistinguished red dwarf star, is the nearest star to our sun - and (in this fiction), the nearest to host a world, Proxima IV, habitable by humans. But Proxima IV is unlike Earth in many ways. Huddling close to the warmth, orbiting in weeks, it keeps one face to its parent star at all times. The 'substellar point', with the star forever overhead, is a blasted desert, and the 'antistellar point' on the far side is under an ice cap in perpetual darkness. How would it be to live on such a world? Yuri Jones, with 1,000 others, is about to find out ... PROXIMA tells the amazing tale of how we colonise a harsh new eden, and the secret we find there that will change our role in the Universe for ever.
