Titan is a little shy. The icy moon stubbornly refuses to pose for detailed photos and stands for the most part, wrapped in its foggy and dissimulating atmosphere.
But NASA has managed to do the impossible and proudly presents a series of photos in which the Titan veil has been dispelled, unveiling the largest moon of Saturn like never before.
The space agency recently presented a set of six images of Titan and which are "some of the clearest and most transparent views" that We have already obtained from this beautiful and enigmatic moon.
According to NASA, snapshots were processed from 13 years of data recorded by a very special camera mounted on the Cassini spacecraft.
Called the Visual and Infrared Spectrometer Mapping Instrument (VIMS), the camera was able to observe the fuzzy atmosphere of Titan and capture images of Saturn's moon in the lengths of the sky. infrared wave. This allowed the instrument to take infinitely more detailed pictures of the icy moon, as the aerosols in Titan's upper atmosphere scatter and absorb less infrared light than visible light.
In the photo above , the center represents Titan. light. The frozen moon is enveloped in its fuzzy, nitrogen-rich atmosphere and appears only in clear clichés when photographed in infrared light, as seen in the photomontage around the centerpiece.
Therefore, the VIMS infrared spectrum of all Cassini instruments – provided the optimal conditions for us to finally look at Titan and observe its spectacular geological features.
"The images are the result of a concerted effort to seamlessly combine the data from the multitude of observations made by VIMS in a wide variety of lighting and visualization conditions during the mission of Cassini ".
The creation of this dazzling mosaic of VIMS images has not been easy, especially since all the data has been collected during different overflights and under different atmospheric conditions, NASA is confident that this latest work represents the pinnacle of Titan imagery. Comparing the recently released Titan photos with older images from the Cassini VIMS archive, the space agency explained the main difference between the two versions. Unlike previous mosaics created by Cassini scientists, the new images have been processed to exclude the seams that normally appear in composite images that assemble images of different resolutions, taken under different lighting conditions and from different angles. 39, a multitude of angles. ] With the seams now gone, this new collection of images is by far the best representation of how the Titan Globe might appear to the casual observer if it was not for the first time. 39, foggy atmosphere of the moon, and it will probably not be replaced "
All this was made possible thanks to a reanalysis of data from the VIMS, coupled with a" manual treatment of mosaics, "revealed the NASA
This incredible effort has been more than rewarding, the world now has a chance to watch Titan unveiled.
