Solar Transits is a procedural exploration of the origins of astrophotography. Each image in this series depicts a randomly generated astronomical event but viewed through the lens of mid-to-late 19th century image capture techniques. The collection features a variety of rare alignments of stars, planets and moons, and are rendered in the spirit of the daguerreotype.

In June of 2012, I took a trip to Minneapolis to speak at the Eyeo Festival. Venus was going to transit while I was there. I was curious. I had not seen a transit before. At 5:09 pm on June 5th, a nearly imperceptible black circle began its march across the sun. Were it not a predicted mathematical certainty, it is doubtful anyone would have noticed. For six minutes, the light from the sun was 0.087% dimmer.

It is a significant thing to see an object silhouetted against the sun. We are so accustom to seeing our perfect circle of pure light that we can't help but to celebrate the occasions where something blocks the view. I still feel a little more excitement when a slight shadow shoots across the landscape on a cloudless day, the source being an extremely rare transit of a commercial jet liner.

Exponentially more rare is the planetary transit. When Venus hangs on the horizon, glowing against the night sky, it is all too easy to think it another star. Only when it is viewed in silhouette can its position in our universe be fully appreciated: orbitally locked like us, and forever drawing it's path around the sun. That tiny black circle effected me in a big way. The scale of the cosmos shifted into perspective. That doesn’t happen often. I was incredibly moved. It was an experience I will never forget. This project is an homage to that strange once-in-a-lifetime event.

As it turns out, I was very lucky to have seen it at all. In the time since my birth in 1972, a Venus transit has only happened twice. The 1st time was in 2004 but I lived in a part of the world where it was not visible. The 2nd time was in 2012. Unless I live to be 145 years old, there won’t be a 3rd time. There are a couple silver linings: the Great American solar eclipse is on April 8 2024, and Mercury will transit in 2032.

The first 10 sales will have the option to purchase their output in the form of a framed daguerreotype.

The Curated Collection includes projects that have been selected by Art Blocks’ Curation Board for their world-class innovation, technical rigor, and aesthetic beauty.

curated

This collection comprises projects screened and selected by Art Blocks and embodies our standards for artistic creativity, conceptual rigor, and technical achievement.

presents

This is the place where we tinker. What lives here is free of theme or architecture but the one common strand is that these projects all grant us delight.

Voyager

INTRODUCTION

Voyager 1 and 2 have been launched in 1977. They are the farthest man crafted objects from Earth. It will take tens to hundreds thousands years for them to reach other stars and planetary systems despite a velocity of 17km/s... 
The on-board camera, mysteriously, sends back images of the remote planets and their moons...

Do not go gentle into that good night.
Rage, rage against the dying of the light.
Dylan Thomas (Do not go gentle into that good night)

ARTWORK DESCRIPTION

The artwork represents a planet and its moons. There is an important variety of planet/moons types, different perspectives (far or near the planet and moons), different space environments (stars, Milky Way, star clusters,  comet, eclipse, Einstein cross and ring, Magellanic Clouds...). A very rare Gravitational Wave affecting space properties can occur. Usually Monochromatic, there is a variation with the addition of one color. In "live view" use the interaction possibilities to explore a given planetary system...

TECHNICAL DETAILS

In the same way photons hit the CCD camera, tiny squares hit the canvas.
The algorithm is minimalist : pick a random position in the canvas and decide if a monochromatic tiny square has to be drawn or not (rarely, squares can be drawn in 2 colors). The light parts are drawn only through the absence of drawing. The whole complexity resides in the decision to draw or not to draw. Mathematical functions are underneath each decision, like space and time are underneath all of our world. 


INTERACTIONS

You can interact with keyboard commands or through URL parameters.
- press S : to save the current image in png
- press 2, 3... 9 (URL, add DP=2) : change resolution. Increase the value step by step. Can be very long to draw, but it's worth it for printing. Very High Resolution can be achieved. The file is saved automatically when finished.
- press L (URL, add liveMode=true) : to discover different views of your planetary system (images will be drawn one after the other, with the same parameters for the main planet and the space environment).
- press F (URL, add fitToScreen=true) : to adapt the artwork to any screen size (artwork is changed but parameters remain the same)
- press M (URL, add monoChromatic=true) : to force the artwork to be monochromatic
- press G (URL, add GW=false) : to remove the gravitational wave effect
- URL, add offset=<Number>, to offset the image production (same planet parameters and space environment)
- URL, add grainy=true, to change the size of the grain (useful for displays to speed up the creation process)

URL Parameters are added to the end of a URL after a ‘?’ symbol, and multiple parameters can be included when separated by the ‘&’ symbol.
You can combine "?liveMode=true&fitToScreen=true&grainy=true" in the URL for display purpose (TV, Art show...). 
Combining liveMode and DP for resolution allows you to save all the images produced.

DISRUPTED STAR

I am a French astrophysicist (PhD) working in high energy astrophysics.
My artist name is related to an astrophysical event in which a star, a pretty common object in the Universe,  comes too close to a Super Massive Black Hole (SMBH), is torn apart and finally tidally disrupted...
The Generative Art plays the role of the SMBH that has changed my life in many ways in the past years...
