Analyzing the Universe

Rutgers puts astronomical observations at the center of learning. Public NASA data and the DS9 imaging tool support investigations of X-ray sources, from white dwarfs and binary systems to supernova remnants and quasars. It suits learners who want to examine measurements and images instead of relying entirely on a lecture-led overview.

What you will learn

• Explore astronomical images with DS9.
• Interpret energy spectra and time-series data.
• Connect observed signals with possible physical explanations.

Who this suits

Learners willing to install and use an imaging tool; the provider lists a beginner level, but data interpretation requires careful practice.

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

Open a public astronomical image in DS9, document the display settings and describe one visible feature. Distinguish the displayed appearance from a physical interpretation of the source.
