This time Vizzuality goes out of the solar system!

NASA's Kepler spacecraft is one of the most powerful tools in the hunt for extrasolar planets. The Kepler team's computers are sifting through the data, but with we are betting that there will be planets which can only be found via the remarkable human ability for pattern recognition.

This is purely an experimental project, we still don't know if humans will do better than computers at finding patterns, but hey, fancy giving it a try?

Our contribution:

  • Information and visual design
  • Front-end development
  • SVG and Protovis

    This time the challenge was double. First, we had to conceptualize and design an friendly interface that could guide the user throw each step of the analysis process. And this still needed to be scientifically valid.

    Secondly, the fluid representation of thousands of elements in a interactive and responsive interface was a great challenge that technically tested our front-end capabilities.


    After some testing and benchmarking over different solutions, we decided to use the Protovis library, a light but powerful data visualization framework.

    Most libraries are not designed for great design customization, and here at Vizzuality we love fully customized experiences. Well, we ended up with lot of tweaking and profiling to get the frontend just as we wanted.


    A pleasant and playful site that takes advantage of the crowdsoucing processing power to speed up scientific discoveries. Another great example of cool citizen science.

    We invite you to visit the site and discover new exoplanets!



    Transit identification

    A drag-and-drop interaction allows to identify accurately the transit position.


    Star classification

    Asking users to classify stars depending on their light curve shape.


    Data visualization optimization

    Due to the amount of star data, we played with several techniques until we got a fluid and responsive interface.

Hey, this site doesn’t support Internet Explorer 6!

Old internet browser flaws and errors are holding back innovation, so we at Vizzuality decided not to support IE6 in our web site. However, you can explore it safely, although you can experience some visualization problems.

By the way, you should really upgrade your browser. Learn why.
