extraterrestrial = of or from outside the Earth or its atmosphere exoplanet = a planet that orbits a star outside the solar system

1. Syllabus

The universe begun with Big Bang about 13.4 billions years ago

Life exists on the Earth

Life may exist on the Exo-planets

Is the Earth isolated from the other system? Is human being unique in the vast universe? Is the birth of the life on the Earth miracle?

Because the Sun is just one unremarkable star among the 100,000 million that populate our galaxy, why should it be the only star to have a train of planets? And why should life be confined to our own Earth?

Purpose of This Course People have long speculated about the possibility of life on a planet other than Earth. We seek for the generality of Earth-like planets and the life in the universe, and consider the place of human beings in the universe. In recent years, the various kinds of materials related to the life have been found by the astronomical observations and space exploration. These discoveries invoke an exogenous origin of organic matter to the early Earth. On the other hand, the advances in the astronomical instrumentation technique have increased the detection of the exoplanetary system. It seems to be a matter of time before the detection of Earth-like planets. In such a situation, we aim to acquire a broad range of general knowledge and advanced expertise by learning the evolution of the universe, the origin of life, exoplanetary systems. To learn these subjects, students are also supposed to study a basic physics and astronomy as well. 12

체험학습 As a part of this class, we plan to visit the GwaCheon National Science Museum late March. At the Museum, they have exhibition to experience cutting-edge astronomy such as solar system objects and exploration of extraterrestrial life. In addition, they have been constructing the new public radio telescope equipped with a SETI (Search for extraterrestrial intelligence) spectrometer there. We aim to study ongoing SETI project in Korea through the visit.
