Knowing the Universe: History and Philosophy of Astronomy

Arizona follows changes in astronomical knowledge from early calendars through Greek science, the Copernican revolution and modern physics. Instruments and methods matter alongside discoveries: the course asks how people could infer something about nature from available evidence. It suits learners interested in the development of scientific reasoning as well as astronomical ideas.

What you will learn

• Trace changes in astronomical models.
• Connect instruments with new observations.
• Explore ideas about stars, space and time.

Who this suits

Beginners interested in the history or philosophy of science; the provider states that no experience is necessary.

Before you enroll

Compare an explanation with the observations supporting it and keep established findings separate from hypotheses. Research develops after a course is recorded, so check dates when following links to missions or discoveries. Workload is a provider estimate; calculations and software setup may require additional time.

Coursera offers paid enrollment or subscription access. Check the enrollment screen for assessment and certificate terms, trials and any financial-aid options. Provider access terms can change; review them before paying.

Put it into practice

Choose one historical change in an astronomical model and explain the observations, assumptions and tools that helped make the change persuasive.
