Objectives
- Understand how science works and explain key astronomical concepts—from sky motions and seasons to Moon phases and eclipses.
- Describe the nature of light, electromagnetic radiation, spectra, and how telescopes and instruments reveal the physical properties of celestial objects.
- Explain the structure and evolution of the Sun and stars, interpret the H‑R diagram, and summarize stellar birth, life cycles, and endpoints.
- Identify the structure of the Milky Way and other galaxies, understand the Big Bang and cosmic evolution, and describe the solar system, exoplanets, and the sea
- How science works: scientific inquiry, measurement, and evidence in astronomy
- Observing the sky: celestial sphere, daily & annual motions, the ecliptic, and Earth’s movement
- Ancient to modern astronomy: from naked‑eye observations to the Copernican revolution and Newton
- Orbits & gravity: Kepler’s Laws, Newton’s synthesis, two‑body motion, satellites, and tides
- Earth–Moon system: seasons, calendars, phases, eclipses, and practical sky‑watching skills
- Light & spectra: electromagnetic spectrum, atomic structure, spectral lines, Doppler effect
- Telescopes & instruments: how we collect light across the spectrum and extract physical information
- The Sun & stars: star colors, brightness, spectra, distances, HR diagram, stellar life cycles
- Interstellar medium: gas, dust, star birth, evolution in the HR diagram, and stellar endpoints
- Galaxies & cosmology: Milky Way structure, galaxy types and distances, expansion of the universe
- Big Bang: age of the universe, CMB, inflation, and the cosmic address
- Solar system: origin, structure, planetary surfaces & atmospheres, small bodies, and exoplanets
- Astrobiology: conditions for life, current efforts to detect biosignatures and technosignatures
Pre Requisites
- Comfort with basic arithmetic and graphs; high‑school algebra helpful but not required
- Curiosity and patience—some ideas (e.g., spectra, gravity) reward careful attention
FAQ
- Q. How long do I have access to the course materials?
- A. You can view and review the lecture materials indefinitely, like an on-demand channel.
- Q. Can I take my courses with me wherever I go?
- A. Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
