Want to help us discover new pulsars?

The Pulsar Science Collaboratory (PSC) is an out-of-school-time citizen science project for students aged 13 and up. Teachers can join too! After training, PSC students and teachers gain access to radio astronomy data collected by the Green Bank Telescope in West Virginia and the Arecibo Observatory in Puerto Rico. PSC members then analyze the data to search for new pulsars.
