EUROPE: A new image-processing technique is bringing Saturn’s largest moon, Titan, into clearer view than ever before.
More than 10 years of observations by the Cassini probe have mapped almost half of the giant moon’s surface. The NASA probe, which is exploring the Saturn system, has uncovered the largest dune fields in the solar system and hydrocarbon lakes that grow and shrink with the seasons on Titan. But now, recent improvements in image processing have made the radar images look better than ever, according to the space agency.
Any picture is going to contain some amount of noise, which typically manifests itself as a grainy, specklelike appearance. But this noise makes it hard for scientists to spot small features or identify changes across the images.
