Gigantic Polar Cyclone and Spinning Hexagon at Saturn's North Pole.


Surrounding this cyclone is a puzzling hexagon-shaped structure, first seen by the Voyager 1 and Voyager 2 spacecraft more than 20 years ago,
and imaged by Cassini last year. Although the hexagon itself is stationary, small white clouds inside the structure move at speeds exceeding 500 km/second, whipping around the hexagon like cars on a racetrack, says Ingersoll.

Intriguingly, the central eye of the northern storm isn’t clear but is covered by a dark cloud 600 km wide, which Cassini scientists have dubbed the bellybutton.

At the south pole, where it’s summer, Cassini took images in visible light and in infrared. The new images show features one-tenth as small as those seen before. Previous visible-light images showed an outer ring of high clouds surrounding what appeared to be a relatively cloud-free region, but the new close-ups reveal a second, inner ring of strong storms.

The outer ring has a diameter of 4,000 km with a wall of towering clouds 40 to 70 km high. The inner ring has about half the diameter of the outer one.

Infrared images of the south show that the entire region is marked by dark cloud spots, an indication of underlying thunderstorm activity similar to that in the north, notes Baines.

In the south, the central eye is clear. “Darned if I know” why a hexagon pattern appears only in the north and not in the south, says Ingersoll.

Earth is a living object. And every living thing is bound to die. There are many theories regarding the origins of Earth. Scientists are also trying to find an answer to another important question: How much longer will the planet be fit to live? Some scientists believe that the fate of Earth has been predetermined i.e. life on Earth will be burned out and destroyed even if each member of the human race should join the “green movement” one of these days.


A recent piece of scientific news came in as a nice surprise for the Russian public. Experts in geodynamics gathered irrefutable evidence about the ongoing movement of the Crimea, which is said to be drifting slowly but surely toward Russia at a speed of 2-3 cm per year. However, those who show lots of enthusiasm at the news may as well wake up in a house on fire. The point is that Earth’s tectonic and geologic processes portend the end of the planet and its subsequent transformation into a star. By and large, the prospects do not look so bright for the species.
