Going boldly forth as a pioneer in the fledgling field of space archaeology, Dr Alice Gorman (aka Dr Space Junk) turns the common perception of archaeology as an exploration of the ancient on its head. Her captivating inquiry into the most modern and daring of technologies spanning some 60 years — a mere speck in cosmic terms — takes the reader on a journey which captures the relics of space forays and uncovers the cultural value of detritus all too readily dismissed as junk. In this book, she takes a physical journey through the solar system and beyond, and a conceptual journey into human interactions with space. Her tools are artefacts, historical explorations, the occasional cocktail recipe, and the archaeologist’s eye applied not only to the past, but the present and future as well. Erudite and playful, Dr Space Junk reveals that space is not as empty as we might think. And that by looking up and studying space artefacts, we learn an awful lot about our own culture on earth. She makes us realise that objects from the past — the material culture produced by the Space Age and beyond — are so significant to us now because they remind us of what we might want to hold onto into the future. ‘As charming as it is expert, as gripping as it is surprising, Dr Space Junk vs The Universe deftly threads together the cosmic and the personal, the stupendousness of space with the lived experience of human beings down here.’ — Adam Roberts, author of Gradisil

A pioneering space archaeologist explores artifacts left behind in space and on Earth, from moon dust to Elon Musk's red sports car. Alice Gorman is a space archaeologist: she examines the artifacts of human encounters with space. These objects, left behind on Earth and in space, can be massive (dead satellites in eternal orbit) or tiny (discarded zip ties around a defunct space antenna). They can be bold (an American flag on the moon) or hopeful (messages from Earth sent into deep space). They raise interesting questions: Why did Elon Musk feel compelled to send a red Tesla into space? What accounts for the multiple rocket-themed playgrounds constructed after the Russians launched Sputnik? Gorman—affectionately known as “Dr Space Junk” —takes readers on a journey through the solar system and beyond, deploying space artifacts, historical explorations, and even the occasional cocktail recipe in search of the ways that we make space meaningful. Engaging and erudite, Gorman recounts her background as a (nonspace) archaeologist and how she became interested in space artifacts. She shows us her own piece of space junk: a fragment of the fuel tank insulation from Skylab, the NASA spacecraft that crash-landed in Western Australia in 1979. She explains that the conventional view of the space race as “the triumph of the white, male American astronaut” seems inadequate; what really interests her, she says, is how everyday people engage with space. To an archaeologist, objects from the past are significant because they remind us of what we might want to hold on to in the future.

If we send a message into space, will extraterrestrial beings receive it? Will they understand? The endlessly fascinating question of whether we are alone in the universe has always been accompanied by another, more complicated one: if there is extraterrestrial life, how would we communicate with it? In this book, Daniel Oberhaus leads readers on a quest for extraterrestrial communication. Exploring Earthlings' various attempts to reach out to non-Earthlings over the centuries, he poses some not entirely answerable questions: If we send a message into space, will extraterrestrial beings receive it? Will they understand? What languages will they (and we) speak? Is there not only a universal grammar (as Noam Chomsky has posited), but also a grammar of the universe? Oberhaus describes, among other things, a late-nineteenth-century idea to communicate with Martians via Morse code and mirrors; the emergence in the twentieth century of SETI (the search for extraterrestrial intelligence), CETI (communication with extraterrestrial intelligence), and finally METI (messaging extraterrestrial intelligence); the one-way space voyage of Ella, an artificial intelligence agent that can play cards, tell fortunes, and recite poetry; and the launching of a theremin concert for aliens. He considers media used in attempts at extraterrestrial communication, from microwave systems to plaques on spacecrafts to formal logic, and discusses attempts to formulate a language for our message, including the Astraglossa and two generations of Lincos (lingua cosmica). The chosen medium for interstellar communication reveals much about the technological sophistication of the civilization that sends it, Oberhaus observes, but even more interesting is the information embedded in the message itself. In Extraterrestrial Languages, he considers how philosophy, linguistics, mathematics, science, and art have informed the design or limited the effectiveness of our interstellar messaging.

From the acclaimed author of Black Hole Blues and Other Songs from Outer Space—an authoritative and accessible guide to the most alluring and challenging phenomena of contemporary science. "[Levin will] take you on a safe black hole trip, an exciting travel story enjoyed from your chair’s event horizon.” —Boston Globe Through her writing, astrophysicist Janna Levin has focused on making the science she studies not just comprehensible but also, and perhaps more important, intriguing to the nonscientist. In this book, she helps us to understand and find delight in the black hole—perhaps the most opaque theoretical construct ever imagined by physicists—illustrated with original artwork by American painter and photographer Lia Halloran. Levin takes us on an evocative exploration of black holes, provoking us to imagine the visceral experience of a black hole encounter. She reveals the influence of black holes as they populate the universe, sculpt galaxies, and even infuse the whole expanse of reality that we inhabit. Lively, engaging, and utterly unique, Black Hole Survival Guide is not just informative—it is, as well, a wonderful read from first to last.

Grab your towel and hitchhike across the galaxy with Australia's most popular scientist Dr Karl Kruszelnicki. Learn about Dr Karl, the universe and everything, and discover how air-conditioning is sexist, how you can kill a spinning hard drive by shouting at it and how space junk is threatening our future capabilities for space travel. Could there be life on one of Saturn's moons? How much power could you collect from all the lightning on Earth? Why do books have book-smell? Why is 10 per cent of the Earth's land area prone to sinkholes? Why are some people chronically late? What would happen if the Earth stopped spinning? Why do most people hardly remember anything from the first half-a-dozen years of their life? How close are we to the Artificial Uterus? Why do some songs turn into "earworms" and stick inside your brain? Why does your hotel room access card get wiped so easily? And is your home WiFi really spying on you?

Scientists have identified at least 100 million pieces of space debris—from paint chips to nonoperational zombie satellites—floating in Earth's orbit. And over 100 tons of those pieces enter Earth's atmosphere each year! Journey into outer space and learn about the dangers of space junk collisions, how scientists track them, and how space agencies are working to develop new technologies to clean up the space junk. Along the way, you'll hear from the scientists who are working to ensure that outer space remains a safe place to travel and explore. If we don't tackle the space junk problem, it might be impossible to travel into space; it could even trap us on Earth.

A collection of eight short stories and novellas in the dark and turbulent world of Alastair Reynolds' Revelation Space universe.Centuries from now, solidarity stretches thin as humanity spreads past the solar system and to the nearest stars. Technology has produced powerful new tools-but lethal risk will always accompany great advancement.And without foresight, opposing groups may fracture multiple worlds. Between the Demarchists and the Conjoiners, the basic right to expand human intelligence-beyond its natural limits-has become a war-worthy cause. Only vast lighthugger starships bind these squabbling colonies together, manned by the panicky and paranoid Ultras. And the hyperpigs just try to keep their heads down.The rich get richer. And everyone tries not to think about the worrying number of extinct alien civilizations turning up on the outer reaches of settled space...because who's to say that humanity won't be next?

From acclaimed science author Jim Baggot, a lively, provocative, and “intellectually gratifying” critique of modern theoretical physics (The Economist). Where does one draw the line between solid science and fairy-tale physics? Jim Baggott argues that there is no observational or experimental evidence for many of the ideas of modern theoretical physics: super-symmetric particles, super strings, the multiverse, the holographic principle, or the anthropic cosmological principle. Unafraid to challenge prominent theorists, Baggott offers engaging portraits of many central figures of modern physics, including Stephen Hawking, Paul Davies, John D. Barrow, Brian Greene, and Leonard Susskind. Informed, comprehensive, and balanced, Farewell to Reality discusses the latest ideas about the nature of physical reality while clearly distinguishing between fact and fantasy, providing essential and entertaining reading for everyone interested in what we know and don’t know about the nature of the universe and reality itself.

An introduction to the laws of celestial mechanics and a step-by-step guide to developing software for direct use in astrophysics research. This book offers both an introduction to the laws of celestial mechanics and a step-by-step guide to developing software for direct use in astrophysics research. It bridges the gap between conventional textbooks, which present a rigorous and exhaustive exposition of theoretical concepts, and applying the theory to tackle real experiments. The text is written engagingly in dialogue form, presenting the research journey of the fictional Alice, Bob, and Professor Starmover. Moving Planets Around not only educates students on the laws of Newtonian gravity, it also provides all that they need to start writing their own software, from scratch, for simulating the dynamical evolution of planets and exoplanets, stars, or other heavenly bodies.
