The fruits of fixation!

Just. Too. Cool.

From Astronomy Pic of the Day comes this very cool photo.

What’s going on?

Here is part of their very cool description:

From solstice to solstice, this six month long exposure compresses time from the 21st of June till the 21st of December, 2011, into a single point of view. Dubbed a solargraph, the unconventional picture was recorded with a pinhole camera made from a drink can lined with a piece of photographic paper. Fixed to a single spot for the entire exposure, the simple camera continuously records the Sun’s path each day as a glowing trail burned into the photosensitive paper. In this case, the spot was chosen to look out over the domes and radio telescope of the University of Hertfordshire’s Bayfordbury Observatory. Dark gaps in the daily arcs are caused by cloud cover, whereas continuous bright tracks record glorious spells of sunny weather. Of course, in June, the Sun trails begin higher at the northern hemisphere’s summer solstice. The trails sink lower in the sky as December’s winter solstice approaches. Last year’s autumn was one of the balmiest on record in the UK, as the many bright arcs in the lower part of this picture testify.

What a great project for a kid!

    Very cool, and as a member of a family growing up with telescopes and a neighbor who was famous in astronomy, I was so fortunate. For home schooling families, these are things one can do with the kids. My poor son was awakened many mornings at four or three or two, to look at various heavenly exhibitions and then do follow up reports and research. Astronomy is one of the course in Classical Education, in the Quadrivium. God bless you and keep showing up these wonderful things…

    Amazing and ingenious! When I was in school, a visiting professor to the maths department gave a lecture showing how often the normal distribution presents itself visually in nature … It might make one think there’s some kind of intelligent ordering to the whole thing ;)
