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, allowing it to rotate to pinpoint planets, stars, asteroids, and other astronomical phenomena across the Universe. A new award from the National Science Foundation (NSF) will ensure it continues operating smoothly. 


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.
