World-wide radio telescope network strengthens evidence for signal that may hint at ultra-low frequency gravitational waves
An international team of astronomers has discovered what could be the early sign of a background signal arising from supermassive black holes, observed through low-frequency gravitational waves. These scientists are comparing data collected from several instruments, including the National Science Foundation’s Green Bank Telescope (GBT.)
Take a FREE self-guided walking tour on site. Hiking and biking are welcome. An observation deck to view the Green Bank Telescope is located in the Jansky Lab parking lot. You can download and print a map for a self guided walking tour here.
Our instruments are extremely sensitive, and many operate 24-hours a day. Smart phones, digital cameras, fitness trackers, and other electronic devices can interfere with observations. Our scientists thank you for leaving these powered off in your vehicle!
Educational groups scheduled for visits and programs in 2022 that are affected by our current operations will be contacted directly. Virtual visits are being offered for groups, learn more here. If you have questions, please contact our Education staff directly at gro.y1656186142rotav1656186142resbo1656186142bg@sn1656186142oitav1656186142reser1656186142.
As these operations continue to evolve, please check back for updates.
Sensitive measurements conducted at the Arecibo Observatory and the Green Bank Observatory may have probed cold regions in our galaxy where molecules are actively being formed from atoms. These regions are the birthplace of molecular clouds, which eventually produce stars.
Einstein’s theory of relativity passes a range of precise tests set by pair of extreme stars
The National Science Foundation’s Green Bank Telescope (GBT) was one of seven radio telescopes around the world whose combined observations of a Double Pulsar reinforce Albert Einstein’s theory of general relativity.
