For a year, the sun in the sky writes out an eight

Categories: Science | Space |

Did you know that, relative to an observer on Earth, the Sun spins an eight in the sky?

We're talking about an analemma. This is a line connecting the points of the Sun's position in the sky at the same time of day throughout the year — if observed from the same geological location. The tilt of the earth's axis creates the appearance that the sun changes its position in the sky every day.

You can do the analemma yourself. All you need is a tripod, a camera and a little patience. Just set the camera in a certain position and take several pictures every day at the same time.
