Title:
Earth at Twilight
Explanation:
No sudden, sharp boundary marks the passage of day into night [ http://antwrp.gsfc.…] in this gorgeous view [ http://eol.jsc.nasa…photo.pl?mission=ISS 002&roll=E&frame=737 7 ] of ocean and clouds over our fair planet Earth [ http://earthobserva…]. Instead, the shadow line or terminator [ http://sci.gallaude…] is diffuse and shows the gradual transition to darkness we experience as twilight. With the Sun illuminating the scene from the right, the cloud tops reflect gently reddened sunlight filtered [ http://webexhibits.…] through the dusty troposphere, the lowest layer of the planet's nurturing atmosphere [ http://liftoff.msfc…atmosphere.html ]. A clear high altitude layer, visible along the dayside's upper edge, scatters blue [ http://webexhibits.…] sunlight and fades into the blackness of space. This picture actually [ http://antwrp.gsfc.…] is a single digital photograph taken in June of 2001 from the International Space Station orbiting at [ http://antwrp.gsfc.…] an altitude of 211 nautical miles [ http://www.gwydir.d…].
