Citizen science platform for exoplanet discovery

2013
Ruby on Rails JavaScript D3.js PostgreSQL

The Challenge

NASA's Kepler telescope generated more light curve data than scientists could analyze. Machine learning missed patterns that human eyes could catch. The platform needed to engage non-scientists in real astronomical research.

The Solution

Built an interactive web application where users classify light curves from Kepler data. The interface makes complex astronomical data accessible and engaging, with real-time feedback and community features.

Results

  • Multiple confirmed exoplanet discoveries
  • Hundreds of thousands of classifications
  • Published in peer-reviewed journals
