Universe Overview Big Bang and Universe Age The universe began approximately 13.8 billion years ago with the Big Bang The universe is constantly expanding, and the expansion is accelerating The observable universe contains an estimated two trillion galaxies The universe’s first stars ignited approximately 180 million years after the Big Bang The first galaxies formed

Introduction Our solar system consists of the Sun and eight planets that orbit it, along with dwarf planets, moons, asteroids, comets, and other celestial bodies. The planets are divided into two main groups: the inner terrestrial planets (Mercury, Venus, Earth, Mars) and the outer giant planets (Jupiter, Saturn, Uranus, Neptune). Each planet has unique characteristics,

Introduction to Astronomy Astronomy is the scientific study of celestial objects (such as stars, planets, comets, and galaxies), the physics, chemistry, and evolution of objects in the universe, and phenomena that originate outside Earth’s atmosphere. Astronomy provides a visual tour of our solar system and beyond, helping us understand our place in the vast cosmos.

Introduction: What is Astronomy? Astronomy is the scientific study of celestial objects (such as stars, planets, comets, and galaxies), the physics, chemistry, and evolution of objects in the universe, and phenomena that originate outside Earth’s atmosphere. Modern astronomy is a multidisciplinary field that incorporates physics, chemistry, mathematics, computer science, and geology to explain the origins

Introduction: What is Astronomical Visualization? Astronomical visualization is the process of transforming complex astronomical data into visual representations that enhance understanding, analysis, and discovery. It bridges scientific data processing and human perception, enabling astronomers to identify patterns, relationships, and phenomena that might otherwise remain hidden in numerical data. From mapping celestial objects to representing abstract

Introduction: What is Astronomical Informatics? Astronomical Informatics combines astronomy, computer science, data science, and information technology to process, analyze, and derive scientific insights from astronomical data. As modern telescopes and instruments generate petabytes of observational data, this interdisciplinary field has become essential for astronomical research. It encompasses data management, computational algorithms, statistical methods, visualization techniques,

Introduction: Understanding Astronaut Training Astronaut training is a rigorous, multi-year process designed to prepare individuals for the extreme conditions and complex operations of spaceflight. This comprehensive program transforms highly qualified candidates from various professional backgrounds (pilots, engineers, scientists, and medical doctors) into mission-ready space explorers. Training encompasses physical conditioning, technical skills, spacecraft operations, scientific procedures,

Introduction: What is Astrology and Why It Matters Astrology is an ancient practice that studies the relationships between celestial bodies and events on Earth, particularly human behavior and personality traits. Dating back thousands of years, astrology has influenced cultures worldwide and continues to be a popular tool for self-reflection, understanding relationships, and navigating life’s challenges.

Introduction: What is an Astrolabe and Why It Matters An astrolabe is an ancient astronomical instrument that serves as an analog computer for solving problems relating to time and the position of celestial bodies. Dating back over 2,000 years, astrolabes were used for navigation, timekeeping, surveying, and astronomical calculations by various civilizations. Understanding astrolabes provides
