The Green Bank Observatory is operated by Associated Universities, Inc. Learn more about our partners and scientific programs here.

National Science Foundation (NSF)

The NSF built the Green Bank Observatory and funded its operation for more than 50 years. Today the NSF still owns the facility and funds part of the operation of the 100-m GBT for “open skies” science.

Breakthrough Listen

Breakthrough Listen is the largest ever scientific research program aimed at finding evidence of civilizations beyond Earth. The GBT plays a key role in the Breakthrough Listen project, and roughly 20% of the time available on the GBT is dedicated to this research.


The GBT is a key instrument for the NANOGrav experiment, and it spends roughly 5% of its time monitoring pulsars to look for gravitational waves.

WVU Center for Astrophysics

WVU time on the 100-m Green Bank Telescope is used by WVU professors and students to pursue their own research projects and interests.
