Lecture 44: The Future of Life in the Solar System Astronomy 141 - Life in the Universe
-
- Kurser
What is the future of life on Earth and in our Solar System? The Sun is
the source of energy for life on the Earth, but it will not shine
forever. This lecture looks at the impact of the various stages of the
evolution of the Sun on the habitability of the Solar System, with
particular emphasis on the continued habitability of the Earth. I will
refer to state-of-the-art computer models of the Sun to get is
properties at various stages in its past and future life. NOTE: Due to
a recorder malfunction this lecture was re-recorded later in the day on
2009 Dec 2, rather than being live from the class room in Smith
Laboratory. As such, it is about 10 minutes longer than usual (my
pacing is off when not in front of class).
