Many discoveries about Venus have been made using Earth-based radio
telescopes, which can transmit powerful radar signals and detect
the weak echoes reflected from the planet's surface.
Arecibo Observatory, Puerto Rico
|At 300 meters (1,000 feet) across, Arecibo is the world's
largest radio "dish." Smaller radio telescopes,
such as the Goldstone Solar System Radar in California, have
also been used to map Venus. Courtesy of David Parker, Science

Map of Venus
This map was produced in 1988 by the Arecibo radio telescope.
Features as small as 1 kilometer (0.6 mile) across are visible.

Green Bank Telescope (GBT)
The new Robert C. Byrd Green Bank Telescope became operational
in August 2000. It has been used in conjunction with Arecibo
to produce more detailed Earth-based images of Venus than
