A view of the Earth during a solar eclipse. The shadow of the Moon can be seen darkening part of Earth. This shadow moves across the Earth at nearly 2,000 kilometers per hour. Only observers near the center of the dark circle see a total solar eclipse - others see a partial eclipse where only part of the Sun appears blocked by the Moon. This spectacular picture of the Aug. 11, 1999 solar eclipse was one of the last ever taken from the Mir space station. Mir was decommissioned after more than ten years of use.
