A rare annular eclipse started in Asia and is moving across the Pacific, set to dissipate over the state of Texas. The eclipse occurs when the moon passes between the Earth and sun at the farthest point of orbit, and making the sun appear as a thin ring around the dark moon. This is first solar eclipse visible in the U.S. since 1994 and viewing parties were organized across the country, from ski lifts to football stadiums. NASA ambassador Patrick Wiggins says he enjoys watching people's reactions. "You get everything from stoic, staring into the sky ... to people breaking down and crying, they're just so moved," he says. Experts warn not to look directly at the eclipse without eye protection.
