A seismology project aimed at understanding the origin and evolution of variable white dwarfs is described. An observing cooperative called the Whole Earth Telescope encompasses many observers at longitudes spaced around the earth, and provides high-resolution power spectra. The light curve of the target star is measured at each site when they are in darkness, and the data are processed in the headquarters in Texas, while an observatory farther west continues the measurements. The lengthening light curve is assembled as the pieces come from around the globe. This real-time operation of the multimirror telescope yields about 10 times more continuous data than have been ever obtained from a single site. The power spectra for the white dwarf star PG 1159-035 and GD 358 are discussed.
