Planets form not from microscopic dust particles but from small pebbles 100-1,000 times larger than ever seen before.

The trailblazers of American radio astronomy called Green Bank Observatory home over 60 years ago. Today, their legacy is alive and well. Nestled in the mountain ranges and farmland of West Virginia, within the National Quiet Zone, radio astronomers are listening to the remote whispers of the universe, in order to discover answers to our most astounding astronomical questions.

Transformative Science for the Next Decade

October 16-18, 2017

With new instruments and improved performance, the 100m Green Bank Telescope is now demonstrating its full potential. On this 60th anniversary of the groundbreaking for the Green Bank Observatory, we are holding a workshop looking toward to the next 10, 20, and even 60 years of the Green Bank Observatory, and invite the community to participate in planning the future.


'Ageless’ Silicon throughout Milky Way May Indicate a Well-Mixed Galaxy

As galaxies age, some of their basic chemical elements can also show signs of aging. This aging process can be seen as certain atoms “put on a little weight,” meaning they change into heavier isotopes — atoms with additional neutrons in their nuclei...


Its huge collecting area 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.
