Description

About two weeks ago I got a picture in which the eye of the polar hurricane was manifested in very subtle way.
This left me uncertain if it really was him because I believe that this is an unprecedented detail in pictures taken by Brazilian photographers.
Now this picture obtained with improved resolution leaves no doubt that I could really grasp it, he outlines perfectly in the center of the hexagon and anyone can see it easily just by looking!
Since its discovery in the 1980s, the hexagonal storm north of Saturn polo has provoked curiosity and speculation, even by scientists.
The Cassini spacecraft to make a close pass can register it in photos and video.

From these data, scientists now know that the eye of the storm is about 2000 km in diameter, 20 times larger than the average size of the eye of a terrestrial hurricane. Fine and bright clouds in hurricane edge are traveling 150 meters per second within a larger structure, known as the hexagon.
The first image of this hurricane and this hexagonal structure was taken by the Voyager spacecraft, when he passed the planet in the 1980s and the structure remained for over twenty years, until the arrival of the Cassini spacecraft.

When the new ship arrived on the planet in 2004, the north pole of Saturn was dark because it was winter in that hemisphere. Still, the probe data and images captured with the infrared spectrometer.
The infrared mapping revealed a huge vortex, but an image with visible light was only possible with the passage of the Saturn equinox in August 2009. And, to see the pole, it was necessary to modify the angle of Cassini's orbit around Saturn, a move which depends on the passage by the moon Titan and requires careful planning, years in advance, to ensure that the spacecraft will have fuel to achieve other planned orbits and do other space meetings.
In the images attached to mine, made by the Cassini spacecraft, the photos show the hurricane in red are false color images (treated to represent certain wavelengths with different color of natural, to highlight aspects that scientists want to study).
