Astronomy is designed to meet the scope and sequence requirements of one- or two-semester introductory astronomy courses. The book begins with relevant scientific fundamentals and progresses through an exploration of the solar system, stars, galaxies, and cosmology. The Astronomy textbook builds student understanding through the use of relevant analogies, clear and non-technical explanations, and rich illustrations. Mathematics is included in a flexible manner to meet the needs of individual instructors.

This downloadeable resource guide, for instructors and students in introductory astronomy courses, focuses on the contributions to astronomy of African, Asian, Hispanic, South Pacific, Islamic, and Native American cultures. It also contains a section on reports and articles for achieving greater diversity in science. Written by Andrew Fraknoi, the guide is part of a series sponsored by the Heliophysics Forum of the Space Missions Directorate at NASA. It includes written, on-line, and audio-visual materials, which can be used directly in the classroom, for student papers, or for personal enrichment.

This focused resource guide, "Black Lives in Astronomy," includes specific written and video resources about and by 25 black astronomers, as well as general materials to examine the history and issues facing black members of the astronomical community. It includes both older, established scientists and people early in their careers. It is aimed at the Astro 101 and amateur astronomer level, and thus does not include any technical materials. I hope this resource will give instructors and students examples of authentic black voices that can be shown in class or used in assignments.

This new annotated guide (part of a series devoted to resources for enjoying or teaching astronomy) features over 250 pieces of music inspired by serious astronomy, including both classical and popular music examples. YouTube links are given for the vast majority, so you (or your students) can listen to them.

Among the pieces included is:
1) a Hubble Space Telescope cantata,
2) eight rock songs about black holes with reasonable science,
3) a supernova piano sonata,
4) a musical exploration of the Messier catalog of nebulae, clusters, and galaxies,
5) a moving song about Stephen Hawking,
6) Moon songs by the Grateful Dead, George Harrison, and the Police,
7) piano pieces “for children with small hands” named after the constellations,
8) operas about Galileo, Kepler, and Einstein,
and many more.

This annotated index includes a wide range of free, online labs appropriate for Astro 101 courses, organized by chapter of the OpenStax Astronomy textbook. So, you can look up free labs on Kepler's Laws, H-R diagram, the Drake Equation, and many other topics in introductory astronomy. These lab activities have been put on line by universities, NASA and NSF sponsored projects, and instructors who want to share their labs with colleagues.

If we have missed any labs that are available free online, please suggest additions by emailing fraknoi@fhda.edu

In this guide, you will find books, articles, and websites that help teachers of astronomy address some of the weird topics on the fringes of science that students sometimes hear about and want to have clarification for. Included are astrology, UFOs as alien spaceships, crop circles, denial of evolution and the big bang, the “face” on Mars, claims that NASA never landed astronauts on the Moon, and others.

A quick resource guide to the use of humor in teaching astronomy, with links to places where astronomy instructors can find cartoons, jokes, and other humorous resources.

This sample syllabus for a course on planets, exoplanets, and SETI (using the OpenStax Astronomy textbook) may help beginning instructors think through what sorts of things they might want to put on a syllabus. It can also provide guidance on how to select key sections of the textbook for a course that doesn’t have time to cover everything.

For decades, the media have given enormous attention to sensational claims that vague lights in the sky are actually extra-terrestrial spacecraft. Recently, there has been a flurry of misleading publicity about UFOs on military photographs. A sober examination of these claims reveals that there is a lot LESS to them than first meets the eye: when there is enough evidence, UFO claims can be explained by terrestrial or celestial phenomena (including lights from human craft and re-entering space junk). This up-to-date guide provides key resources available free on the Web, to help scientists, educators, students, and journalists learn about the skeptical perspective (and the background stories) behind these claims.

See Note at End. This is a guide to science fiction stories and novels which are based on reasonably good science (and can thus be recommended in introductory astronomy courses.) The stories are organized by astronomical topic. While most of the stories are available only in print, a number are now published electronically free of charge, and links to those are included.

This listing includes a wide range of short videos (15 minutes or less) that can be used in introductory astronomy courses.  It is organized by the chapter topics in the OpenStax Astronomy textbook.  We don’t include simulations.  To suggest other video that you have found particularly useful for Astro 101 courses, please drop a line to the compiler at: fraknoi@fhda.edu

This is a first attempt at making an annotated list of plays and films that are specifically about astronomers. No claim is made for completeness and additional suggestions are most welcome.

I don't list operas here. A list of astronomy operas is included in my topical listing of music inspired by astronomy at: http://bit.ly/astronomymusic

This updated resource suggests some of the best places on the web for astronomy instructors to obtain high-quality images for showing in class (and gives the direct URL for obtaining the photos). It includes general sources, such as the Hubble image gallery and NASA’s Planetary Photojournal, as well as more specific sources for a particular observatory or wavelength range.

This new astronomical calendar, compiled by textbook lead author, Andrew Fraknoi lists, month by month, 158 astronomical anniversaries and birthdays that are important for the history of our understanding of the universe. While many such calendars exist, this one differs by focusing on real astronomical research (and not so much on anniversaries of human space flight.) And it includes a more diverse group of scientists, including more women and more people of color.  The calendar is available without charge at: http://bit.ly/astrodates  

Please note: An updated, expanded version of this guide for 2022 is available at: http://bit.ly/womenastronomers

This is a guide for Astronomy 101 instructors (and other educators) on the issues that have faced women in astronomy and the work of some of the women who can serve as role models for the next generation. Written by Andrew Fraknoi (Foothill College), it is part of a series called “Unheard Voices,” sponsored by the Heliophysics Forum of the Space Missions Directorate at NASA. The guide includes written, on-line, and audio-visual materials, many of which can be used directly in the classroom or for student papers. It features sections on: the history of women in astronomy in general, materials on selected women astronomers of the past, issues facing women in astronomy today, and materials on selected contemporary women astronomers.
