Soon More Day than Night :-)

The profile of the atmosphere and a setting sun are featured in this image photographed by an Expedition 15 crewmember on the International Space Station (June 2007).

Known as the equinox, the geocentric astronomical event marks the first day of spring in the northern hemisphere and autumn in the south. Equinox means equal night and with the Sun on the celestial equator, Earth dwellers will experience nearly 12 hours of daylight and 12 hours of darkness.

We that live far north will experience NO NIGHT AT ALL some time soon now. In St.Petersburg, Russia, they call these days of summer WHITE NIGHTS.

NASA suggest we celebrate equinox with this wonderful picture of the Earth's atmosphere!
