Description: Introduction to the search for life in the universe for the non-science major. Earth`s location in space and time, nature of life, light and the spectrum, origin and history of the universe, origin of life on Earth and the possibility of life on other planets.



MCCCD Official Course Competencies
1. Apply the scientific method and basic concepts of astronomy, geoscience, life science, and chemistry to describe and understand the ongoing search for life in the universe. (I-IX)
2. Summarize the history of the universe which led to the formation of galaxies, stars and our solar system. (I-II)
3. Describe in terms of energy, wavelength and frequency the various portions of the electromagnetic spectrum (III)
4. Describe the astronomical techniques used to detect and measure properties of exoplanets and analyze their place in models of solar system formation. (II-IV)
5. Define the essential characteristics of a habitable environment. (II-IX)
6. Analyze the characteristics of other planets and evaluate their suitability for developing and sustaining life. (II-VII, IX)
7. Describe impact cratering, tectonic, volcanic, and atmospheric processes which contribute to a habitable environment. (III, V-IX)
8. Describe how Earth`s environment, working through natural selection, has produced diversity of species. (VI-VII)
9. Critically assess potential changes in Earth`s environment that may occur as a result of human activity or environmental processes. (V-IX)
10. Construct estimates of the likelihood of extraterrestrial life. (I-IX)
