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 jet of particles and radiation toward Earth.

West Virginia Students Use One of World’s Largest Telescopes

Governor’s STEM Institute brings nearly sixty rising 9th graders to Green Bank Observatory

This July 2022, nearly 60 students gathered in Green Bank, West Virginia, for the Governor’s STEM Institute (GSI.) These rising 9th graders competitively applied for this opportunity to experience science, technology, engineering, and mathematics through exciting hands-on experiences. 


Radio “heartbeat” teases Fast Radio Burst origins

A recent article in Sky and Telescope shared the latest observations of Fast Radio Bursts (FRBs) from the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope, located in British Columbia.

CHIME is constructing a smaller version its main telescope at the Green Bank Observatory (GBO). This new outrigger will work in tandem with other CHIME instruments to better locate the position of FRBs by triangulating their signals, similar to the way cell phone GPS works.
