The "story" of Our World in Space begins by grounding the reader in humanity’s historical perspective. For much of human history, Earth was mistakenly considered the center of everything. Asimov traces the intellectual journey that gradually dismantled this misconception, moving from ancient views like Ptolemy's to the revolutionary insights of Copernicus, Galileo, and Newton. This opening sets the stage by emphasizing that understanding space is fundamentally about humility and a willingness to transcend self-centered views. This is where the "story is building from"—a foundation of shifting human perspective, driven by observation and intellectual courage.

From this historical context, the book meticulously builds its understanding of our true cosmic address: the Solar System. Asimov starts with Earth, not as an isolated entity, but as an integral part of a larger structure, detailing its characteristics like size, atmosphere, orbit, and its crucial relationship to the Sun. He highlights how precisely Earth's conditions are tuned to support life, noting its stable orbit, magnetic field, and atmosphere. The narrative then expands, moving outward to the Moon, explaining its influence on Earth’s tides and its significance in human imagination and exploration. The Moon, though lifeless, serves as a quiet record, revealing geological history through its craters and plains.

The central engine of this cosmic narrative is the Sun, which Asimov dedicates considerable attention to. He explains its composition, internal fusion processes, and dynamic electromagnetic phenomena, establishing it as the fundamental source of warmth and light essential for Earth. From there, the "story" systematically explores each planet: Mercury, Venus, Mars, the gas giants like Jupiter and Saturn with their unique features, and the distant ice giants Uranus and Neptune, even including Pluto as the ninth planet at the time of writing. Each celestial body is presented not merely as a fact, but as a distinct entity contributing to the grand tapestry of our solar neighborhood.

Beyond the known planets, the book delves into the asteroid belt, which Asimov characterizes not as mere debris, but as time capsules—remnants of unformed planetary material offering clues about the solar system's formation. Further out, comets are introduced as ancient visitors from the Oort Cloud and Kuiper Belt, their fleeting appearances near the Sun revealing mysteries of their distant origins. This progression from the familiar Earth to the edges of the Solar System is a carefully constructed "plot" element, designed to incrementally expand the reader’s sense of scale.

The "story" then truly ventures into deep space, introducing stars and galaxies. Asimov categorizes stars by their properties and explains their life cycles, from their birth in nebulae to their dramatic deaths as white dwarfs, neutron stars, or black holes. He presents stars as dynamic, evolving systems, and then places our own Solar System within the context of the Milky Way, a galaxy of hundreds of billions of stars. This grand scale is conveyed through analogies and a steady layering of understanding, demonstrating that comprehension comes from seeing the vast interconnections within the universe.

A significant "chapter" in the book's narrative is dedicated to space exploration. Written in the 1970s, it celebrates early achievements like Sputnik and Apollo, interpreting them as humanity's first physical steps into the universe it had long studied from afar. Asimov addresses the inherent challenges of spaceflight—distance, radiation, life support—and optimistically contemplates a future with space stations, lunar bases, and missions to Mars. His tone, while not utopian, reflects a compelling logic that life and thought inherently seek to expand and reach further.

The ultimate "lead to" of Our World in Space is a profound reflection on meaning. Asimov argues that realizing Earth's smallness does not diminish humanity but rather elevates it. The ability to comprehend the universe's vastness, to measure galaxies, predict stellar lifespans, and send probes to its edges, is presented as humanity's triumph: our awareness. This intellectual journey culminates in a powerful message: despite our physical insignificance, our capacity for understanding and wonder is immense.

Robert McCall’s illustrations are presented as an indispensable part of this "story," visually echoing Asimov's scientific and philosophical ideas. They are described not merely as decorations, but as sweeping interpretations that blend with the text to create a tone of "expansive wonder, balanced by scientific clarity".

Finally, the book’s "resolution" circles back to Earth. After the expansive cosmic journey, Asimov reminds the reader of our home world’s fragility. The knowledge gained about the cosmos is not meant to inspire nihilism, but rather stewardship. Earth, life, and intelligence are presented as rare and precious, making it our responsibility to protect the cradle of consciousness, even as we continue to reach for the stars.

In essence, Our World in Space tells the "story" of human perception, detailing how it expands and deepens with each scientific discovery. It is a compelling review of how humanity has come to see itself, urging readers to understand that space is not just distant, but something we are already part of. The book's "plot" is therefore the unfolding of this grand cosmic perspective, leading the reader from a self-centered view to a humble yet empowered understanding of their place in an incomprehensibly vast and wondrous universe.
