Longest exposure photograph

The adjacent picture is one of the longest exposure photographs. And the exposure was for 15,552,000 seconds or 6months!!

Photographer Justin Quinnell strapped the camera to a telephone pole overlooking the Gorge, where it was left between December 19, 2007 and June 21, 2008–the Winter and Summer solstices. This dream-like picture shows each phase of the sun over Bristol’s Clifton Suspension Bridge taken during half a year.

The image was captured on a pin-hole camera made from an empty drinks can with a 0.25mm aperture and a single sheet of photographic paper.

Solargraph’ shows six months of the sun’s luminescent trails and its subtle change of course caused by the earth’s movement in orbit. The lowest arc being the first day of exposure on the Winter solstice, while the top curves were captured mid-Summer.

(Dotted lines of light are the result of overcast days when the sun struggled to penetrate the cloud.)

The Sun

Found this beautiful pic of the Sun on the web. This one’s recently captured by SDO (Solar Dynamics Laboratory).

SDO: The Solar Dynamics Observatory is the first mission to be launched for NASA’s Living With a Star (LWS) Program, a program designed to understand the causes of solar variability and its impacts on Earth. SDO is designed to help us understand the Sun’s influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.

SDO’s goal is to understand, driving towards a predictive capability, the solar variations that influence life on Earth and humanity’s technological systems by determining

  • how the Sun’s magnetic field is generated and structured
  • how this stored magnetic energy is converted and released into the heliosphere and geospace in the form of solar wind, energetic particles, and variations in the solar irradiance.

So what’s this blog about?

Another attempt? Well yes. Attempting to figure out another sustainable model (there are some other attempts going on parallel-ly). Well, we have a lot of questions in mind. we read up stuff, we do some research to find answers to these questions. This is an attempt to publish that little 15-20 minute research.
