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. Images such as the below helped scientists understand the orbit change resulting from DART’s impact.(more…)
This October, students attending the triennial PhysCon conference embarked on an adventurous detour to the National Science Foundation’s Green Bank Telescope (GBT).
Nearly 900 undergraduate astronomy and physics majors from across North America came together in Washington, D.C. for PhysCon, hosted by the Society of Physics Students (SPS) and its associated honor society, Sigma Pi Sigma.(more…)
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.)
Frank Drake, one of the first scientists to come to Green Bank and the National Radio Astronomy Observatory, died at his home in Aptos, California on September 2.(more…)

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.(more…)
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.(more…)
