Students Discover Millisecond Pulsar, Help in the Search for Gravitational Waves

A special project to search for pulsars has bagged the first student discovery of a millisecond pulsar – a super-fast spinning star, and this one rotates about 324 times per second. The Pulsar Search Collaboratory (PSC) has students analyzing real data from the National Radio Astronomy Observatory's (NRAO) Robert C. Byrd Green Bank Telescope (GBT) to find pulsars. Astronomers involved with the project said the discovery could help detect elusive ripples in spacetime known as gravitational waves.

"Gravitational waves are ripples in the fabric of spacetime predicted by Einstein's theory of General Relativity," said Dr. Maura McLaughlin, from Western Virginia University. "We have very good proof for their existence but, despite Einstein's prediction back in the early 1900s, they have never been detected."
