"The GBT already enables transformative advances in astronomy," Harshal Gupta, the NSF program officer for Green Bank Observatory, said in a statement.

"Using the telescope, astronomers from the NANOGrav team recently detected the most massive neutron star, a discovery with implications for understanding the limit at which such stars collapse to form black holes.". One of the world's most advanced radio observatories sprawls across the Atacama Desert. [21][22][23], In July 2014, the United States Senate Committee on Appropriations approved the NSF's fiscal year 2014 budget, which did not call for divestment of the GBT in that fiscal year. In the mid-1950s, the United States was falling behind the rest of the world in radio astronomy because of difficulty finding funding. Sort by.

With a big dish comes a big responsibility: load of data analysis. "There's nothing else like it in North America and there never will be," said Felix J. Lockman, principal scientist at the Green Bank Observatory.

Its 100-meter diameter collecting area, unblocked aperture, and good surface accuracy provide superb sensitivity across the telescope's full 0.1–116 GHz operating range. A new document describing some of the discoveries made by scientists using the Green Bank Telescope is now available on the NRAO science web site. The Green Bank Telescope can be used to do chemistry, physics, radar receiving, and astronomy and has no equal in the world. A companion project uses the GBT’s sensitivity to map the brightness of hydrogen in large volumes of space, preparing a kind of cosmic web of unseen matter to weave among the seen galaxies. The Green Bank Telescope can be used to do chemistry, physics, radar receiving, and astronomy and has no equal in the world. STONE COASTER.
