Planetary Defense & Science Will Advance With New Radar on Green Bank Telescope
With less power than a microwave, prototype produced highest resolution images of Moon ever captured from Earth With a transmitter less powerful than a microwave oven, a team of scientists and engineers used the National Science Foundation’s Green Bank Telescope (GBT) and Very Long Baseline Array (VLBA) to make the highest-resolution radar images of the…

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…

The Green Bank Telescope & Next Generation RADAR
The Next Generation Radar program (ngRADAR) is a collaboration between the National Radio Astronomy Observatory (NRAO), Green Bank Observatory (GBO), and Raytheon Space & Intelligence. Together they will create an active radar system for GBO’s 100-meter Green Bank Telescope (GBT) using the latest solid-state technology. For twenty years, Green Bank Observatory’s 100-meter radio telescope has…

Are astronomers seeing a signal from giant black holes?
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…

NASA’s Mars Perseverance rover landing observed by the Green Bank Telescope
This “waterfall image” is actually three separate observations combined to show NASA’s Mars Perseverance rover as it enters the Martian atmosphere before touching down on the red planet. Green Bank Observatory Data Analyst Amber Bonsall created this image using data received by the Green Bank Telescope (GBT). The GBT was pointed at Mars to observe…
