Our Universe

What is our place in the Universe? How did stars, planets, and galaxies form? Could life exist beyond Earth? The minor Our Universe invites you on a journey through space, time, and society. You will explore the scientific story of modern astronomy, the origins of life, and the role of the cosmos in human culture.   Through interactive courses, you will learn about cosmic evolution, exoplanets, space exploration, and astronomy’s impact on society. You will develop scientific reasoning skills, engage in hands-on observations at the Old Observatory, and critically assess the intersection of science and culture. This minor welcomes students from all academic backgrounds and encourages interdisciplinary perspectives on the Universe.

Why Choose This Minor?

• Explore astronomy in a way that connects to your field of study
• Gain scientific reasoning, data interpretation, and critical thinking skills
• Experience real telescope observations and interactive simulations
• Engage with ethical and societal questions about space and science

For Whom?

Open to all bachelor students, except those enrolled in Leiden Astronomy/Physics BSc and TU Delft Aerospace Engineering. Whether you study history, biology, law, philosophy, or anthropology, this program offers a unique opportunity to explore astronomy’s role in shaping our understanding of the Universe.

Program Structure

The minor Our Universe is a 30 EC full-time program running from September to January. A half-minor (15 EC) option is available by completing only Block 1.

Block 1: Foundations of the Universe

• The Evolving Universe (5 EC) – Explore the life cycle of stars, galaxies, and the Universe’s large-scale evolution.
• The Habitable Universe (5 EC) – Investigate the formation of stars, planets and the conditions necessary for life.
• Imagining the Universe (5 EC) – Analyze and apply the portrayal of astronomy in literature, art, and science fiction.

Block 2: Exploring and Engaging with the Universe

• Exploring the Universe (5 EC) – Study how humanity has viewed and explored the cosmos, from ancient civilizations to modern astrophysics.
• Observing & Simulating the Universe (5 EC) – Gain hands-on experience with telescopes and astronomical simulations.
• Astronomical Dilemmas (5 EC) – Examine ethical and societal questions surrounding astronomy, such as space exploration, environmental concerns, and cultural heritage.

Learning Outcomes

By the end of this minor, students will:

• Understand the major components of the Universe and their evolution – such as galaxies, stars, planets, dark matter and dark energy.
• Recognize the role of physical laws in shaping cosmic events.
• Apply scientific reasoning to astronomical observations and simulations.
• Critically assess scientific claims and their portrayal in media.
• Explore the cultural and societal implications of astronomy.
• Reflect on humanity’s place in the cosmos and the ethical dimensions of space exploration.
