*This project is currently paused.* The goal of this project is to measure the winding of spiral arms in galaxies. This winding parameter has been linked to other parameters that are more time consuming and difficult to measure, such as the black hole mass in a galaxy's nucleus. With your help we can measure how tightly wrapped spiral arms are in galaxies and identify interesting candidates for future, detailed telescope observations. On average, people find the tasks to be moderately easy.
