Autumn Equinox photo challenge:
On the journey around the Sun we are approaching another key moment in our celestial dance with our star. Next Friday September 23rd is the Autumn Equinox. Equinox means equal night, and that day Earth is in balance. There are approximately 12 hours of day and 12 hours of night. In a sense the planet is in neutral, but from that moment onward the northern hemisphere marches towards Autumn while the southern hemisphere approaches Spring. In the north days will be getting shorter and the Sun won't rise as high in the sky and it will gradually get colder.
To mark this moment we plan on featuring the best photos on our blog next week friday that reflect the Equinox. What we're looking for are shots that show the Sun and it's relationship to our planet and the journey into Autumn, or Spring if you live down-under. Let your imagination run wild. The more creative the better! Get those shutters snapping and see what you can capture.
To ensure they are considered for this special feature email them to [email protected], or add them to our photography pool or hashtag your photos with #bbc23degrees on twitter.

my question: wouldn't balance be achieved more at a time when earth is not tilting at all, which of course can never happen
