Explanation: If you went outside at the same time every day and took a picture that included the Sun, how would the Sun's position change? A visual answer to that question is an analemma, a composite image taken from the same spot at the same time over the course of a year. The featured analemma was composed from images taken every few days at noon near the village of Callanish in the Outer Hebrides in Scotland, UK. In the foreground are the Callanish Stones, a stone circle built around 2700 BC during humanity's Bronze Age. It is not known if the placement of the Callanish Stones has or had astronomical significance. The ultimate causes for the figure-8 shape of this and all analemmas are the tilt of the Earth axis and the ellipticity of the Earth's orbit around the Sun. At the solstices, the Sun will appear at the top or bottom of an analemma. The featured image was taken near the December solstice and so the Sun appears near the bottom. Equinoxes, however, correspond to analemma middle points -- not the intersection point. In two days there will be an equinox ("equal night"), when day and night are equal over all of planet Earth. Many cultures celebrate a change of season at an equinox.

Wow.
Awesome.
An actual picture taken by the opportunity probe on Mars of a Martian Analemma.
Cool. The autumnal equinox is the 22nd this year.
“autumnal equinox”
Sob...goodbye to another summer.
Just had my first Pumpkin Donut and a sip of fresh apple cider of the Fall season!
Those Callanish must have been exceptionally brave. They had huge stones. Grossly mishappen but buge.
I dated Ana in high school.
A huge bowling pin.
Makes me want to go to the snack bar for a delicious cheeseburger.
I flunked out of Junior High or else Ana would have picked me.
Her sister Diane dropped out too, maybe that could have been a match. Her nickname was Di.
