Introduction to Astronomy surveys the solar system, stars, stellar evolution, and galaxies, using scientific and quantitative reasoning to inform space-science decisions.
What ASTR 100 covers
Prerequisite: MATH 105, STAT 200, or a more advanced MATH or STAT course. An examination of the major areas of astronomy.
Topics include the solar system, stars and stellar evolution, and galaxies. Current topics in astronomy are also discussed. The objective is to use scientific and quantitative reasoning to make informed decisions about topics related to space science.
Typical ASTR 100 assignments
Expect an assignment requiring you to apply scientific and quantitative reasoning to a current astronomy topic and connect it to an informed decision about space science.
Key topics in ASTR 100
- The solar system
- Stars and stellar evolution

Writing tips for ASTR 100
Follow the assignment instructions and rubric line by line
UMGC assignments for ASTR 100 are graded against a specific rubric or grading criteria your instructor provides — every requirement has to be visibly addressed. Skipping a requirement because it seems minor is one of the most common reasons a strong submission loses points.
Ground claims in specific evidence, not general impressions
ASTR 100 expects claims to be grounded in specific, cited evidence — historical sources, scientific data, or documented research — not broad generalizations or personal impressions.
Connect the topic to informed, real-world decision-making
UMGC's general-education science and studies courses consistently frame content around using reasoning to make informed real-world decisions — an assignment that stays purely descriptive without that decision-making connection is missing a piece the rubric typically wants.

Why students seek help with ASTR 100
Students sometimes describe an astronomical phenomenon without the quantitative reasoning component ASTR 100 specifically requires — the rubric typically wants that quantitative grounding shown, not description alone.
