I love this picture from the Astronomy Picture of the Day website. The description of the photo from the website is very technical:
What’s that strange light down the road? Dust orbiting the Sun. At certain times of the year, a band of sun-reflecting dust from the inner Solar System appears prominently just after sunset—or just before sunrise—and is called zodiacal light. Although the origin of this dust is still being researched, a leading hypothesis holds that zodiacal dust originates mostly from faint Jupiter-family comets and slowly spirals into the Sun. Recent analysis of dust emitted by Comet 67P, visited by ESA’s robotic Rosetta spacecraft, bolster this hypothesis. Pictured when climbing a road up to Teide National Park in the Canary Islands of Spain, a bright triangle of zodiacal light appeared in the distance soon after sunset. Captured on June 21, the scene includes bright Regulus, alpha star of Leo, standing above center toward the left. The Beehive Star Cluster (M44) can be spotted below center, closer to the horizon and also immersed in the zodiacal glow.
Actually, the picture means more to me than that. Whenever I travel, I like to leave around sunrise. I imagine the road stretching out before me on the way to my destination. The journey itself is meaningful, almost irrespective of the destination. If I am flying, I make a point to get to the airport hours before the flight, and I make the airport into an intermediate destination, with surprises of its own.
If I am driving, I like the idea of getting out of Los Angeles traffic before most people have woken up. When the sun rises, I like to be in open country, which in the context of Southern California, usually means the desert.
To me, life is travel. It is something of a truism that life’s a journey … but it really is. It is a journey on which we have little notion of the destination. So I resolve to enjoy the journey as much as possible. Who knows what wonders may await us?
