For the second time in as many years, a student has made a discovery while participating in the Pulsar Search Collaboratory (PSC), a joint program between the National Radio Astronomy Observatory and West Virginia University designed to get students and teachers involved in analyzing data from the Robert C. Byrd Green Bank Telescope (GBT). This time it was high school sophomore Shay Bloxton, who discovered a brand new pulsar. "For Bloxton, the pulsar discovery may be only her first in a scientific career. 'Participating in the PSC has definitely encouraged me to pursue my dream of being an astrophysicist,' she said, adding that she hopes to attend West Virginia University to study astrophysics. Late last year, another West Virginia student, from South Harrison High School, Lucas Bolyard, discovered a pulsar-like object called a rotating radio transient. His discovery also came through participation in the PSC."
