The four faces of Titan
Upper left: Titan's leading hemisphere (faces Earth at greatest eastern
elongation). Upper right: the anti-Saturn hemisphere. Lower right:
the trailing hemisphere (faces Earth at greatest western elongation).
Lower left: the Saturn-facing hemisphere. Ground based astronomers
have established that, at longer wavelengths to which Titan's haze
is nearly invisible, Titan is consistently brightest just after
eastern elongation (between upper left and upper right images). The
darkest side (from the ground based observers) is near western elongation
(lower right).
These images are a mosaic made from the original 850LP images (
that is, the Hubble images have not been deconvolved). The total contrast
is only plus or minus about 4% of the total light collected through the
filter. The grey area at the top and bottom
shows regions which could not be imaged through the haze
. The gap in coverage extends
to near the equator at about 10 deg longitude (top left) due to a
96 hour gap in coverage.
