To determine if a course is remote, hybrid, or in-person use the catalog search tool to narrow results. Otherwise, when browsing courses, the section indicates teaching mode:
Teaching modes (remote, hybrid, in-person) are subject to change at any point. Please pay close attention when registering. Depending on the timing of a teaching mode change, faculty also may be in contact with students.
The science of astronomy spans vast scales of space and time, from individual atoms to entire galaxies and from the universe’s beginning to the future fate of our Sun. In this course, we will survey some of the main ideas in modern astrophysics, with an emphasis on the physics of stars and galaxies. ASTR 111 is the first course in the Astrophysics and Astronomy major sequences. It is also appropriate for students planning to major in one of the other sciences or mathematics and for others who would like a quantitative introduction that emphasizes the relationship of contemporary physics to astronomy. Topics include gravity and orbits, radiation laws and stellar spectra, physical characteristics of the Sun and other stars, star formation and evolution, black holes, galaxies, the expanding universe, and the Big Bang. Students will also use telescopes remotely to observe stars, nebulae, planets, and galaxies and to make daytime observations of the Sun.
Format: lecture/laboratory; This is a hybrid course. Lectures will be provided both in-person and for remote viewing. Students will work in small groups on discussions and calculations. Each group can choose to meet remotely or in class. Students can switch groups, and groups can switch format, as needed. Prof. Jaskot will meet with remote groups during their discussion to answer questions. The class has 6 afternoon labs, with both in-person and remote options. Remote observing sessions will occur throughout the semester.
Grading: yes pass/fail option,
yes fifth course option
weekly problem sets, one hour-long test, a final project, lab reports, and an observing portfolio
a year of high school Physics, concurrent college Physics, or permission of instructor, and MATH 140 or equivalent
potential Astronomy majors
The course requires regular problem sets and quantitative assignments. The course will emphasize how physical equations explain the observed properties of the universe.
