Earth's Orbit

As Earth orbits the sun, its position in the sky changes because our planet's axis is tilted.

Ho-hum, you say? Jennifer at Conversion Diary has some pictures on her blog of sunrise at an airport. They're taken at the summer and winter solstices (longest day, longest night), and the autumnal equinox (equal day and night). Scroll down to #6 on her "Quick Takes" list.

Is that not TOO COOL?
