Long live Cassini, who delivered to date the clearest views of the Saturn moon Titan.

Six infrared images of Titan were captured by the noble Cassini spacecraft, which eventually (and unfortunately) exploded into Saturn's atmosphere in September 2017 after 13 years of exploration.

The images are some of the clearest global views of the lunar surface so far. You can spy on Titan's icy surface in incredibly clear details.

According to NASA, the photos were taken with 13 years of combined data from the Cassini spacecraft taken by an on-board device called a visual and infrared mapping spectrometer.

During a large number of fly-bys, during the Cassini mission, VIMS performed a series of observations under different light, atmosphere, and visibility conditions, resulting in the six detailed views shown above. These images are especially special, as previous mapping trials revealed obvious seams between different areas on the surface of titanium – these seams were manually processed by imaging scientists, a rather time-consuming task.

"After the seams, this new collection of images are by far the best representation of how the Titan's globe might appear to the casual observer, if it were not for the hazy atmosphere of the moon, and it probably will not be replaced for some time ", according to NASA's online statement. 19659013] The clearest views of Saturn's moon Titan still enclose the moon's natural hazy color.

Titanium is also not as easy to photograph as the moon is surrounded by a strong haze, according to NASA, this is due to small particles cited in the upper atmosphere of titanium as aerosols and scattering visible light, Cue Cassini's VIMS, which used infrared wavelengths to divide the haze and capture those incredibly clear images.

Did you wonder exactly what you did Seen here? From the pictures, scientists have found that titanium ei It has a rather complex surface with innumerable geological features. The team used the so-called "band ratio" color technique to distinguish between areas on the Titan surface. You can see the equatorial dune fields in brown and what areas of water-ice-enriched areas might be in blue and purple.

Since the launch of the Cassini spacecraft in 1997, she has been exploring Saturn and its many moons, including Titan in 2004. Although it is unfortunately gone now, we are still reaping the rewards.
