Title:
A Radar Image of Venus
Explanation:
The largest radio telescopes in the world are working together to create a new map of the surface of Venus. The surface of Venus [ http://www.nineplan…] is unusually hidden by a thick atmosphere [ http://bigmac.civil…] of mostly carbon dioxide [ http://scifun.chem.…] gas. These thick clouds [ http://antwrp.gsfc.…] are transparent, however, to radar signals [ http://spaceplace.j…] sent and received from Earth. The two radio telescopes [ http://www.setileag…] generating the most powerful radar ever are the Arecibo Telescope [ http://antwrp.gsfc.…] in Puerto Rico [ http://www.cia.gov/…] and the new Robert C. Byrd Green Bank Telescope [ http://www.gb.nrao.…] in West Virginia [ http://www.state.wv…]. The new survey will resolve details as fine a one-kilometer across, and will be inspected for changes since the last major radar map [ http://antwrp.gsfc.…] was made by NASA's Magellan spacecraft [ http://www.jpl.nasa…] that orbited Venus [ http://antwrp.gsfc.…] from 1990 to 1994. Pictured above [ http://www.aoc.nrao…] is part of a preliminary image showing details as small as five-kilometers across.
