APOD: 2009 September 24 - Equinox Sunset
The caption reads:
Often inspiring, or offering a moment for contemplation, a sunset is probably the most commonly photographed celestial event. But this uncommonly beautiful sunset picture was taken on a special day, the Equinox on September 22. Marking the astronomical change of seasons, on that day Earth dwellers experienced nearly 12 hours of daylight and 12 hours of darkness (an equal night). Reflected in the calm waters of Lake Balaton with a motionless sailboat in silhouette, the Sun is setting due west and heading south across the celestial equator. In the background lies the Benedictine Archabbey of Tihany, Hungary.
Astronomy is a hobby of mine and this site is a fabulous collection of pictures from NASA sources. I highly recommend this site for everyone as the images are gorgeous and fascinating.
Cheers.
