The Evolving Universe

Caltech takes a broad view of the physical universe, connecting its major constituents across ten weekly sections. Planetary systems share the syllabus with stars, galaxies, black holes and quasars. This is a useful option for learners who want a conceptual map of astronomy before choosing a narrower topic or a data-analysis course.

What you will learn

• Connect planetary systems with larger cosmic structures.
• Explore stars, galaxies and compact objects.
• Develop a broad astronomy vocabulary.

Who this suits

Learners seeking an introductory survey across astronomy; the provider assigns a mixed level rather than a specific prerequisite sequence.

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

Draw a scale diagram linking a planetary system, a galaxy and the wider universe. For each scale, write one observation scientists use to investigate it.
