Abstract: | Several automated optical telescopes have been setup at appropriate longitudes around the globe to study earthshine variations
and asteroseismology. The first telescope has been setup at Teide Observatory, Tenerife, Spain in October 2004. The intensity
of earthshine relates to the average of Earth’s albedo, and in turn relates to the global temperature of the Earth. A global
network is necessary because each site can measure the earthshine reflected from only a part of the Earth. The network will
also be used for asteroseismology study. It can measure photometric variations of pulsating stars. The long-term and continuous
measurements allow the accurate determination of mode frequencies of stellar pulsations, which provides information on the
properties of stellar interior. |
