The space probe Cassini discovered a new radiation belt, located above the clouds of Saturn — down to the ring D. It lies closer to the planet than all the belts have been found earlier.

In addition, the ship has revealed strong differences between the current storms, from those that watched the Voyager spacecraft in the 1980s, and more — opened the night glow of Titan.

Devices probe capture radio signals over a wide frequency range, which arise from lightning. According to the frequency and number of strokes, scientists judged the frequency and duration of storms on the planet.

It turned out that from one day to another — varies the frequency of storms. From the very rare until relatively frequent. While a year visit the station Voyager storms frequently and constantly.

Such differences scientists explain changes in the position of the shadow of the rings on the surface of the planet — now and twenty years ago.

Then the rings covered by a narrow portion of the sun at the equator of the planet. The atmosphere there is cooled, while the next remained relatively hot spots.

The neighborhood is very hot areas to cold led to a powerful and constant storms.

Now shadow rings wider then lies in the northern hemisphere, where the atmospheric temperature and so low. Extreme changes in temperature over short intervals does not work.

In addition, the surprises continue to bring Titan — the largest moon of Saturn.

The probe discovered that its atmosphere extends much further than previously thought — more than 700 kilometers above the surface of the subject methane and carbon monoxide.

But the most amazing thing is that these gases fluoresce (under sunlight) in the visible and infrared ranges.

Even on the night side of Titan is constantly glow that clearly hurt to sleep locals if they were there.
