- The Sun is the star at the center of the Solar System. It is a massive, hot ball of plasma, inflated and heated by energy produced by nuclear fusion reactions at its core. Part of this internal energy is emitted from its surface as light, ultraviolet, and infrared radiation, providing most of the energy for life on Earth.
- Douglas County — Thumbnail History (historylink.org)
Douglas County is a predominantly rural county located in north central Washington. Waterville is the county seat. The county’s proximity to Grand Coulee Dam just over the county line (spanning the Columbia River between Okanogan and Grant counties), as well as the four Columbia River dams within the county have over time provided work for thousands of Douglas County residents.
