Although the study of astronomy has ancient roots, it is now one of the most rapidly developing and exciting subjects in modern science. Astronomy is the study of the Universe and its contents: planets, stars, black holes, galaxies, and quasars. Each of these is a fascinating topic in its own right, but perhaps the greatest achievement of modern astronomy has been to gather them all into a rich and coherent picture, one which depicts the origin and evolution of all things from the Big Bang to the development of living organisms. Recent advances in astronomy have derived from new technologies that have yielded instruments of unprecedented power: telescopes with 10-meter mirrors, orbiting satellite observatories for all parts of the electromagnetic spectrum, deep space missions to sample planetary atmospheres and surfaces, and huge laboratories for detection of elusive cosmic neutrinos and gravity waves. The excitement and accessibility of astronomy are featured in frequent press coverage of major new discoveries, including in recent years the discovery of planets orbiting other stars, a comet crashing into Jupiter, the discovery of very young galaxies in the distant universe, the detection of gravitational waves from merging black holes, the possibility of life on Mars, the threat of asteroid collisions with the Earth, and the detection of primordial ripples in the cosmic background radiation. Astronomy draws from, and contributes to, many other subjects: primarily physics but also geology, atmospheric and environmental science, biology, and even philosophy. The coursework of the two Astronomy majors offers students the opportunity to explore these frontier discoveries while simultaneously developing fundamental analytical and quantitative skills useful in many different careers. A total of 35 Astronomy courses are open to majors. The Astronomy major (BA) offers a concentration on science in the context of a liberal arts degree for students who do not intend to pursue graduate training in astronomy or physics. It is often part of a double major. The Astronomy-Physics major (BS) provides more rigorous preparation for graduate work in astronomy, physics, computer science, or related fields.
