The GBT, is the world’s premiere single-dish radio telescope operating at meter to millimeter wavelengths. Its enormous 100-meter diameter collecting area, its unblocked aperture, and its excellent surface accuracy provide unprecedented sensitivity across the telescope’s full 0.1 – 116 GHz (3.0m – 2.6mm) operating range.


Proposed Changes for Green Bank Observatory Operations

The National Science Foundation has announced two public scoping meetings and a public comment period for the planned environmental impact statement and proposed changes to Green Bank Observatory operations. The public scoping meetings will be held on November 9, 2016 from 3-5pm and 6-8pm at the Green Bank Observatory Science Center.


"Open Skies" Science

The National Science Foundation funds part of the operation of the 100-m GBT for scientific research by the US community. This time is likely to decrease in the coming years.


It's huge collecting area is what allows us to see these incredibly small energies that we're trying to study, The types of energies we look at are less than the energy of a single snowflake falling on the earth.
