Moon’s Tycho Crater Revealed in Intricate Detail

Powerful new radar technology will reveal secrets of the Solar System

Partially processed view of the Tycho Crater at a resolution of nearly five meters by five meters and containing approximately 1.4 billion pixels, taken during a radar project by Green Bank Observatory, National Radio Astronomy Observatory, and Raytheon Intelligence & Space using the Green Bank Telescope and antennas in the Very Long Baseline Array. This image covers an area 200km by 175km, which is large enough to contain the 86km-diameter Tycho Crater. Credit: NRAO/GBO/Raytheon/NSF/AUI

COVID-19 Safety Operations

In response to the health concerns posed by COVID-19, the Green Bank Observatory has made changes to its public programs and events.

Learn more about how to access the Science Center, bus tours, and other guided programs here.

Tour tickets are required to enter the Science Center. These can be purchased at our online store.

At this time, occupancy to the Science Center, cafe, and gift shop is limited to ensure safety. Purchase your ticket online before you visit to ensure your reservation.

Masks are required to be worn by those two years and older over nose and mouth while inside Science Center, buses, and participating in any of our activities. THIS IS STRICTLY ENFORCED FOR THE SAFETY OF OUR STAFF AND ALL VISITORS.

Virtual tours, live streams, and video updates on Observatory news and education are also available, tune in here.

As these operations continue to evolve, please check back for updates.

Take a FREE self-guided walking tour on site. Hiking and biking are welcome. An observation deck to view the Green Bank Telescope is located in the Jansky Lab parking lot. You can download and print a map for a self guided walking tour here.

Learn more about biking onsite here.

Visit the Galaxy Gift Shop online.

Try these educational resources and activities at home.

Our instruments are extremely sensitive, and many operate 24-hours a day. Smart phones, digital cameras, fitness trackers, and other electronic devices can interfere with observations. Our scientists thank you for leaving these powered off in your vehicle!

Educational groups scheduled for visits and programs in 2021 that are affected by this change in operations will be contacted directly. Virtual visits are being offered for groups, learn more here. If you have questions, please contact our Education staff directly at reservations@gbobservatory.org.
