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…

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.…
