From Ancient Philosophy to Modern Space Exploration

What you'll learn
- Understand what astrobiology is and explain the scientific study of life in the universe.
- Describe the origin and evolution of life on Earth from prebiotic chemistry to complex organisms.
- Evaluate planetary habitability, including conditions on Mars, icy moons, and exoplanets.
- Interpret biosignatures, the Fermi Paradox, and the Drake Equation using scientific reasoning.

Requirements
- No prior knowledge required. A basic interest in biology, space, or science is enough.

Description
Have you ever wondered how humans first began asking whether life exists beyond Earth, and how that single question grew into one of the most fascinating scientific fields of our age? This course invites you into a sweeping, 2,500-year journey, one that begins with ancient philosophers gazing at the night sky and leads all the way to modern spacecraft exploring distant worlds. We start with the earliest cosmological ideas from ancient civilizations, Greek atomists, and Islamic scholars who kept the debate on plural worlds alive. From there, we move into the era of Copernicus, Kepler, and Galileo, whose discoveries revolutionized our place in the universe and opened the door for modern scientific thought. You will also explore how Darwin, Lamarck, and early evolutionary biologists reshaped our understanding of life's origins and diversity on Earth, setting the foundation for asking where life might arise elsewhere. As we enter the Space Age, the course examines the birth of NASA's Exobiology Program, the Viking landers on Mars, early laboratory experiments on prebiotic chemistry, and the scientific controversies that shaped astrobiology as a discipline. We then follow today's missions to Mars, Europa, Enceladus, and Titan, exploring how modern instruments search for biosignatures, organic molecules, and habitable environments. Finally, we turn to the age of exoplanets—worlds orbiting other stars—and learn how telescopes like JWST analyze their atmospheres for hints of life. Whether you are a student, a science lover, or someone who simply wonders about our cosmic origins, this course provides a complete, engaging, and accessible introduction to the history of astrobiology and the scientific quest to understand life in the universe.

Who this course is for:
- Anyone curious about life in the universe, students, science enthusiasts, beginners in biology or astronomy, and those exploring astrobiology for the first time.
