What will happen to Green Bank’s NRAO facility?

The Green Bank Telescope’s massive 2.3-acre dish is A giant bucket to collect faint radio waves that pour down from space objects. In radio astronomy, this means that the GBT is very sensitive to ultra-faint hydrogen clouds that hang between stars and galaxies.

How do radio telescope arrays work?

Each antenna collects radio waves that need to be combined in a clever way, allowing Astronomers produce images comparable in detail to giant telescopes to the separation between the component telescopes. Using a computer and signal processing, all of these signals are combined to create a high-resolution image.
