CNDSN3 month 18 days (Sina) March 18th Beijing time news, Venus high resolution radar image acquired in 2012, is a collaboration between the Arecibo Observatory and the Green Bank telescope, reveal the mountains, craters and Venus volcano landform. At that time, the radar signal through the earth and the atmosphere of Mars Arecibo Observatory issued to Mars surface, after reflection and then received by the green bank telescope.

This approach is called "bistatic radar". "Pioneer" Venus probe photo taken on 1979, shows a mysterious "Y" shape ". According to Spanish astronomers proposed theory, this phenomenon caused by the strong wind cloud. On Venus, the wind speed at the top and bottom of the Y shape faster, eventually created a mysterious.

In the eyes of ground-based optical telescope, Venus is heavy is mainly made of carbon dioxide shrouded in clouds, it is difficult to see the surface of the earth. In order to pierce this layer "cloud veil", astronomers will be the Green Bank telescope in West Virginia America (right) radar transmitter and Puerto Rico Arecibo Observatory (left) together, to capture the details of surprising Venus from earth surface scene.
