Venus Cloud Patterns: (colorized and filtered) |
Original Caption Released with Image:
This picture of Venus was taken by the Galileo spacecrafts Solid State Imaging
System on February 14, 1990, at a range of almost 1.7 million miles from the
planet. A high pass spatial filter has been applied in order to emphasize the
smaller scale cloud features, and the rendition has been colorized to a bluish
hue in order to emphasize the subtle contrasts in the cloud markings and to
indicate that it was taken through a violet filter. The sulfuric acid clouds
indicate considerable convective activity, in the equatorial regions of the
planet to the left and downwind of the subsolar point (afternoon on Venus).
They are analogous to 'fair weather clouds' on Earth. The filamentary dark
features visible in the colorized image are here revealed to be composed of
several dark nodules, like beads on a string, each about 60 miles across. The
Galileo Project is managed for NASA's Office of Space Science and Applications
by the Jet Propulsion Laboratory; its mission is to study Jupiter and its
satellites and magnetosphere after multiple gravity assist flybys at Venus and
Earth.
