Celebrate the Supermoon Total Lunar Eclipse at Green Bank Observatory

Sunday, May 15th a total lunar eclipse of a supermoon will be visible to most of us in West Virginia (weather permitting) between the hours of 10:30pm and 2am Eastern Time. The start and end of the lunar eclipse’s ‘totality’ is between 11:30pm and 1am. No special equipment is needed to view a lunar eclipse, although an optical telescope or binoculars can make it more exciting!


Future of Earth’s Defense is Ground-based Planetary Radar

Green Bank Telescope will be largest fully steerable antenna in the world capable of transmitting radar signals for research

A new radar system being developed by the National Radio Astronomy Observatory and the Green Bank Observatory will transmit powerful radar signals from the Green Bank Telescope (top right panel) and, in this illustration, bounce those signals off the Moon (middle right). The reflected signal can be received by antennas of the Very Long Baseline Array, in various locations across the U.S., Hawaii, and the Virgin Islands (bottom right). The combination of antennas acts as a giant, high-resolution radar imaging system.

Powerful radar systems have played a major role in the study of planets, moons, asteroids, and other objects in our Solar System for several decades, and now have a “unique role” to play in planetary defense – “providing protection to the nations of the world from devastating asteroid and comet impacts,” according to the newly released Planetary Science and Astrobiology Decadal Survey 2023-2032. The National Radio Astronomy Observatory (NRAO) and the Green Bank Observatory (GBO) are developing new capabilities for the Green Bank Telescope (GBT) and the Very Long Baseline Array (VLBA) that will make them key instruments for meeting this need.


Drake Lecture: Alyssa Goodman

Saturday April 23rd, 7pm

Dr. Alyssa Goodman is a Professor of Astronomy at Harvard University and a Research Associate at Smithsonian Institution. She will share her amazing experience as an astronomer and about data visualization as the next frontier in astronomy and astrophysics. 

The Drake Lecture honors the legacy of Frank Drake, who created his famous equation and launched the Search for Extraterrestrial Intelligence as a scientist in the early days of the Green Bank Observatory.

This free public lecture will be held in the Green Bank Science Center auditorium at 7:00 pm on Saturday, April 23. Free tickets must be registered for in advance; walk-ins cannot be admitted.

Attend in person.

Watch the live stream from home!
