LISA: Detecting gravitational waves from space

The Laser Interferometer Space Antenna (LISA) is a proposed joint NASA-ESA mission whose goal is to detect low frequency (1e-4 Hz to 1e-1 Hz) gravitational waves. Expected sources include binary stars in our galaxy, extra-galactic massive black holes, and possibly gravitational radiation left over from the big bang. In this talk, I will briefly describe the LISA mission and the science that LISA will be able to do with its observations.
