Galileo's quick look at Venus.

Galileo's quick look at Venus

Scientists have finally received the pictures of Venus' atmosphere taken in February by the Galileo spacecraft as it whipped around the planet -- one of a series of maneuvers that will give Galileo the speed needed to propel it to Jupiter, where it should arrive in 1995.

Many spacecraft have looked at Venus' clouds, but Magellan both photographed the cloud tops and recorded near-infrared amissions from deeper clouds. The lower cloud patterns differ distinctly from those at the top, report Galileo scientists analyzing the images radioed to Earth from the craft on Nov. 19 to 21. The near-infrared images revealed convection zones within clouds due to rising heat, while the cloud tops appeared fluffier--due to reflected sunlight--in the visible-light photos.
