ASTR 1200 - Stars and Galaxies
Primary Instructor - Fall 2020
Non-science majors are introduced to the nature and workings of the Sun, stars, neutron stars, black holes, interstellar gas, galaxies, quasars, plus structure and origins of the universe. Some lectures may be held at Fiske Planetarium. Offers opportunities to attend nighttime observation sessions at Sommers-Bausch Observatory. Degree credit not granted for this course and ASTR 1020 or ASTR 1040.
