Teaching

courses taught

ASTR 1000 - The Solar System
Primary Instructor - Summer 2019
Introduction to the night sky, planets, moons and the life in our solar system. Highlights the latest discoveries from space. For non-science majors. Some lectures may be held at Fiske Planetarium. Offers opportunities for nighttime observations at Sommers-Bausch Observatory. Similar to ASTR 1010, but without lab. Degree credit not granted for this course and ASTR 1010 or ASTR 1030.
ASTR 1200 - Stars and Galaxies
Primary Instructor - Fall 2019 / Fall 2021
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. Same as ASTR 1020 and ASTR 1040.
