This is a book on planets: Solar system planets and dwarf planets. And planets outside our solar system – exoplanets. How did they form? What types of planets are there and what do they have in common? How do they differ? What do we know about their atmospheres – if they have one? What are the conditions for life and on which planets may they be met? And what’s the origin of life on Earth and how did it form? You will understand how rare the solar system, the Earth and hence life is. This is also a book on stars. The first and second generation of stars in the Universe. But in particular also on the link between planets and stars – brown dwarfs. Their atmospheric properties and similarities with giant exoplanets. All these fascinating questions will be answered in a non-technical manner. But those of you who want to know a bit more may look up the relevant mathematical relationships in appendices.

Until the mid-1990s, scientists only guessed that the universe held exoplanets, or planets beyond our solar system. But using advanced physics and powerful telescopes, scientists have since identified more than three thousand exoplanets. This work has revealed fascinating worlds, including a planet that oozes lavalike fluids and a planet that glows bright pink. Even more fascinating, scientists think that some exoplanets might contain life. Many orbit in the Goldilocks zone, the region around a star that's not too hot or too cold for liquid water, a key ingredient for life. This book examines exoplanets, the possibilities for life beyond Earth, and the cutting-edge technologies scientists use to learn about distant worlds.

Describes the science of planet hunters, the prospects for the discovery of alien life, and discusses the controversies surrounding extrasolar-planet research.

Simulated universes created by post-human artificial intelligence are a common theme in 21st century hard sci-fi. Suddenly in 2023, we're capable of realizing these literary dreams by virtue of engineering an interface for neural networks advanced enough to simulate human language and visual art beyond the ability of us average simple country folks. The technological hurdles are behind us. Now it's just a matter of concentrated effort on par with any moderately successful tech start-up or community theater ensemble. We're going to have an AI-generated simulated universe comparable to our own in complexity and accessible interactivity. This book is a guide to content creation, and to the responsible humanitarian development of such an unprecedented wonder!

In her autobiographic Graphic Novel "The World Beyond My Shadow" awarded artist and writer Daniela Schreiter describes her childhood and youth with Asperger syndrome. She tells her story about a life on "the wrong planet" in wonderful pictures and with a great sense of humor. This book helps to understand what it means to live with Asperger's and is an entertaining read at the same time.

Leading planetary scientists give personal accounts of their work, and their desire to understand and explore worlds beyond our own.

Part 1: Introduction to Exoplanets This section sets the stage for the captivating world of exoplanets. It begins by shattering the traditional view of a singular solar system and reveals the vast multitude of exoplanets estimated to exist in our Milky Way. You'll explore different types of stars and their potential for hosting planets, understanding how diverse the stellar landscape is. Next, you'll journey through the thrilling "Hunt for Alien Worlds," learning about the various methods scientists use to detect these distant objects. From the transit method that tracks starlight dips to the radial velocity technique that measures star wobbles, this section unveils the ingenuity and challenges of exoplanet discovery. You'll also meet powerful space telescopes like Kepler, TESS, and James Webb, playing crucial roles in this cosmic detective work. Wrapping up Part 1 is a "Gallery of Exoplanet Diversity," showcasing the incredible variety of planets found beyond our solar system. From rocky super-Earths and gas giants like Jupiter to scorching hot Jupiters and potential ocean worlds, you'll discover the awe-inspiring range of planetary characteristics out there. The chapter even introduces intriguing rogue planets, solitary wanderers unbound to any star. Part 2: Unveiling the Secrets of Exoplanets Now that you've met these fascinating worlds, Part 2 takes you on a journey to uncover their secrets. "Peering into Atmospheres" explores how scientists analyze the light filtering through planets' atmospheres, searching for chemical signatures like water vapor, methane, and oxygen - potential fingerprints of life. This section emphasizes the challenges of atmospheric characterization and the cutting-edge techniques used to overcome them. Moving on, "The Habitability Puzzle" delves into the concept of the habitable zone, the orbital range where liquid water, a key ingredient for life as we know it, could exist on a planet's surface. You'll explore factors affecting habitability, like stellar radiation, atmosphere composition, and internal heat, gaining a deeper understanding of what might make a planet life-friendly. This section also introduces the exciting search for Earth-like planets and the hunt for biosignatures, potential biological markers. Finally, "Life Beyond Earth" delves into the realm of astrobiology, the study of life beyond our planet. This chapter explores different possibilities for life forms on exoplanets, ranging from extremophiles thriving in harsh environments to potentially complex organisms. You'll also learn about the search for extraterrestrial intelligence (ETI) and ongoing SETI programs, raising the tantalizing question: Are we alone in the universe? Part 3: The Future of Exoplanet Exploration With a sense of wonder about the future, Part 3 takes you on a voyage towards what's next. "Next-Generation Telescopes and Missions" introduces groundbreaking instruments like the James Webb Space Telescope and the European Extremely Large Telescope, showcasing the technological advancements driving exoplanet research. This section highlights the exciting possibility of directly imaging Earth-like planets, offering unprecedented glimpses into these distant worlds. However, exploration comes with responsibility. "The Ethical Considerations" explores the potential impact of finding extraterrestrial life on humanity and emphasizes the importance of planetary protection protocols to avoid contaminating exoplanets. This section underlines the necessity of international collaboration in exoplanet research, ensuring global stewardship in this endeavor.
