“Don’t give up, it will happen.” Virtual Workshop Celebrates the 20th Anniversary of the Green Bank Telescope

Just over twenty years ago, in the summer of the year 2000, the National Science Foundation’s Green Bank Telescope (GBT) was dedicated for service. Taller than the Statue of Liberty, with a dish that can hold two football fields, the GBT remains the largest fully steerable radio telescope in the world. To celebrate the creation of such a colossal instrument, and the scientific research made possible, the Observatory will be holding a special virtual workshop April 21st to 22nd, GBT@20: Twenty Years of Innovation and Discovery.

Construction of the unprecedented design of the Green Bank Telescope took ten years. NSF/NRAO

Earth Is Safe From Asteroid Apophis for 100-Plus Years

Green Bank Telescope Teams Up With NASA’s JPL Goldstone Deep Space Communications Complex to Track Asteroid

The near-Earth object was thought to pose a slight risk of impacting Earth in 2068, but now radar observations have ruled that out.

Scientists uncover warehouse-full of complex molecules never before seen in space

Radio observations of a cold, dense cloud of molecular gas reveal more than a dozen unexpected molecules

Polycyclic aromatic hydrocarbon molecules overlaid on the Taurus Molecular Cloud, a large blue-white cloud made of gas and dust with large and small stars of varying luminosities interspersed throughout. Aromatic molecule structures shown in order from left to right: 1-cyanonaphthalene, 1-cyano-cyclopentadiene, HC11N, 2-cyanonaphthalene, Vinylcyanoacetylene, 2-cyano-cyclopentadiene, benzonitrile, E-cyanovinylacetylene, HC4NC, propargylcyanide.

Can Green Bank Telescope Defend Against Asteroid Apophis?

The National Science Foundation’s Green Bank Telescope (GBT) is teaming up with NASA’s Goldstone Deep Space Communications Complex (GDSCC) to observe this potentially hazardous asteroid. These new observations of Apophis will allow scientists to improve their understanding of the asteroid’s orbit, and better estimate the odds that Apophis could strike the Earth in the future. Predicting if there is a real chance of impact, decades ahead of time, gives scientists the opportunity to take action to manipulate the orbit of Apophis to avoid a collision in the future.

NASA’s Mars Perseverance rover landing observed by the Green Bank Telescope

NSF/GBO/JPL/NASA/Amber Bonsall

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 communications from the rover as it landed February 18th, 2021 at 3:55 p.m. EDT.
