  • GBT Scans 12 Planets for SETI Search

    The Robert C. Byrd Green Bank Telescope (GBT), part of the Green Bank Observatory in West Virginia, is the world’s premiere single-dish radio telescope. Between its 100-meter dish (328-foot), unblocked aperture, and excellent surface accuracy, the GBT provides unprecedented sensitivity in the millimeter to meter wavelengths—very high to extremely high frequency (VHF to EHF). Since…


  • GBT, SETI, & the WOW Signal: the Search Continues…

    New radio observations of a distant Sun-like star thought to be a likely source of the famous WOW! signal reveal no evidence that the system harbors anything (or anyone) capable of sending such a signal. Nonetheless, astronomers say the “null result” is an important step in verifying a new, more targeted approach to searching nearby stars for…

  • Scientists Reveal Secrets to Burping Black Hole with the Green Bank Telescope

    The National Science Foundation’s Green Bank Telescope (GBT) has revealed new information about mysterious radio bubbles surrounding a supermassive black hole.  


  • NASA DART Imagery Produced with GBT Data Shows Changed Orbit of Target Asteroid

    Analysis of data obtained over the past two weeks by NASA’s Double Asteroid Redirection Test (DART) investigation team shows the spacecraft’s kinetic impact with its target asteroid, Dimorphos, successfully altered the asteroid’s orbit. This marks humanity’s first time purposely changing the motion of a celestial object and the first full-scale demonstration of asteroid deflection technology.…


  • GBT data extends SETI search to extragalactic distances

    An international team of astronomers has extended the reach of the Search for Extraterrestrial Intelligence (SETI) Breakthrough Listen project, thanks to data from the National Science Foundation’s Green Bank Telescope (GBT.)


  • Green Bank Observatory Receives $5.3 million from National Science Foundation To Repair Foundation of One of World’s Largest Telescopes

    The Green Bank Telescope weighs in at 17 million pounds, making it one of the largest movable manmade structures on Earth. Photo credit Jay Young. The National Science Foundation’s Green Bank Telescope (GBT) is one of the world’s largest moving structures. Sixteen wheels carry 17 million pounds on a steel track atop a concrete foundation,…


  • GBT data contributes to image of new black hole captured by EHT

    In April 2017, as the Event Horizon Telescope (EHT) collaboration prepared to point the world’s most powerful radio telescopes at the Milky Way’s supermassive black hole, Sagittarius A*, the team calibrated its instruments by observing another cosmic target. Located about 3.7 billion light-years away, J1924–2914 is a blazar: an active black hole that ejects a…
