Intro Astronomy 2014. Class 13: Galaxies, the Universe, Life

In my 13th and final class of my Introduction to Planetary Science and Astronomy course at CSUDH, I cover the Universe (a nice small topic) including the Big Bang, dark matter, dark energy, galaxies, life and more. The video is below. For more information about the class, see my class page,

This lecture covers galaxies (our place in the Milky Way, types of galaxies, Hubble Deep Field), the Universe (determining distances, expansion of the universe, Big Bang theory and evolution of the universe, WMAP and Planck results, dark matter, dark energy, neutrinos), and life in the universe (Earth life requirements, astrobiology, SETI). Recorded at California State University Dominguez Hills.
