ASTR 101. Introduction to the Sun and Its Planets (3). This introductory astronomy course describes our solar system of planets and how astronomers develop our physical understanding about the universe. Topics include the properties of the Sun and planets; the formation of the solar system and how the planets have evolved over time; asteroids, comets, and dwarf planets; and a comparison of our solar system with new planetary systems being found around other stars. This course has no pre-requisites. (Formerly known as ASTR 201: The Sun and Its Planets. Not available for credit for astronomy majors.)

ASTR 103. Introduction to Stars, Galaxies and the Universe (3). This introductory astronomy course describes the universe we live in and how astronomers develop our physical understanding about it. Topics covered include: the properties of stars; the formation, evolution, and death of stars; white dwarfs, pulsars, and black holes; spiral and elliptical galaxies; the Big Bang and the expansion of the Universe. This course has no pre-requisites.  (Formerly known as ASTR 202: Stars, Galaxies, and the Universe. Not available for credit to astronomy majors.)

ASTR 105. Introduction to Einstein’s Universe (3). This course is a descriptive introduction for the non-science major to Einstein’s Special and General Theories of Relativity and how these theories have fundamentally altered our understanding of the universe. Topics discussed will include: time dilation, length contraction, the twin paradox, the warping of space-time, white dwarf stars, neutron stars, black holes, the structure and evolution of the universe. No mathematical background beyond simple algebra is needed. This course has no pre-requisites. (Formerly known as ASTR 204: Einstein’s Universe)

ASTR 107. Introduction to Life in the Universe (3). This course is intended to introduce the non-scientist to the field of astrobiology — the interdisciplinary study of, and the search for, extraterrestrial life and the conditions for extraterrestrial life in the Universe.  This course has no pre-requisites.  (Formerly known as ASTR 206: Life in the Universe. Students may receive credit for ASTR 107 or USNA 217 (Astrobiology), but not for both.)

ASTR 151. Doing Astronomy (1). This course is intended to introduce students to how astronomy is done. The course will focus on the astronomical research process, including ongoing research activity in the department and on career paths in astronomy. This course is largely intended for first- and second-year students considering majoring or minoring in astronomy. Prereq: First- or second-year academic standing.

ASTR 221. Stars and Planets (3). Stellar structure and energy production. Formation and evolution of stars. Supernovae, neutron stars, and black holes. Star clusters.
