"Open Yale Courses provides free and open access to seven introductory courses taught by distinguished teachers and scholars at Yale University. The aim of the project is to expand access to educational materials for all who wish to learn."
"This course focuses on three particularly interesting areas of astronomy that are advancing very rapidly: Extra-Solar Planets, Black Holes, and Dark Energy. Particular attention is paid to current projects that promise to improve our understanding significantly over the next few years..."
Materials include the course syllabus, and searchable transcripts, audio and video resource files to download.
Hands-On Astronomy: Observing Stars and Planets
"This course features a complete set of lecture notes that cover topics such as explanations for celestial coordinates and time and tips for keeping an observing notebook. There are also notes on elementary optics, electronic photography, and image processing."
Introduction to Astronomy
"Introduction to Astronomy provides a quantitative introduction to the physics of the solar system, stars, the interstellar medium, the galaxy, and the universe, as determined from a variety of astronomical observations and models."
The Solar System
"This is an introduction to the study of the solar system with emphasis on the latest spacecraft results. The subject covers basic principles rather than detailed mathematical and physical models. Topics include: an overview of the solar system, planetary orbits, rings, planetary formation, meteorites, asteroids, comets, planetary surfaces and cratering, planetary interiors, planetary atmospheres, and life in the solar system."
Introduction to General Astronomy
"A description of modern astronomy with emphasis on the structure and evolution of stars, galaxies, and the Universe. Additional topics optionally discussed include quasars, pulsars, black holes, and extraterrestrial communication." Instructor Josh Bloom
Astro C10 / LS C70U Introduction to General Astronomy
"Astro 10 - Fall 2007 - A description of modern astronomy with emphasis on the structure and evolution of stars, galaxies, and the Universe. Additional topics optionally discussed include quasars, pulsars, black holes, and extraterrestrial communication, etc. Individual instructor's synopses available from the department."
Telescopes and Spectrographs
"This unit looks at how telescopes and spectrographs are designed to improve our ability to observe the universe. You will examine how different technologies have been developed over the last four hundred years to enable us to look deep into space."
The evolving Universe
"The ‘Big Bang’ is said to be the origin of our Universe. This unit will help you to comprehend what happened in the moments immediately after the Big Bang and during the initial cooling period. You will also gain an understanding of how this event turned in to the Universe we live in today."
"The sun dominates our lives by defining our day, but how much do you know and understand about it? This unit will help you to explore the workings of the brightest star in our universe looking at its structure and the main processes taking place within it. You will also examine the phenomena of sun spots."
