The findings were made in Uranus when the Voyager 2 spacecraft flew past the planet in 1986 not highlighted by spectacular, so that Uranus has been considered a planet since boring and has not been seen or investigated much.
Now this could change radically. Thanks to a new technique applied in the Keck Observatory in Hawaii, Uranus is being revealed through high resolution infrared images, as a world of amazing weather.
The blue-green planet’s atmosphere is full of hydrogen, helium and methane, the primary condensable gas Uranus. Winds blow mainly from east to west, with speeds up to 900 kilometers per hour (about 560 mph), although small amounts of energy available to them. Uranus’s atmosphere is similar to that of Neptune, the coldest planet in our solar system, with temperatures of around 220 degrees Celsius, cold enough to freeze the methane.
Great weather systems, probably much less violent storms on Earth as we know, behave strangely on Uranus.
Some of these weather systems remain fixed latitudes and suffer large variations in their activity. Others are seen floating toward the planet Ecuador while experiencing great changes in size and shape.
There discovered by the team of Larry Sromovsky and Pat Fry, both from the University of Wisconsin-Madison, Heidi Hammel of the Association of Universities for Research in Astronomy (AURA), and Imke de Pater of the University of California at Berkeley, reveals an astonishing complexity of Uranus atmospheric phenomena.
The complexity weather Uranus is disconcerting. The main drive of the climate should be solar energy, because there is no detectable internal power source. But Uranus Sun rays are 900 times weaker than on Earth because it is 30 times farther from the Sun, so it does not get the amount of solar energy required to drive the system. Instead, weather variations observed do not seem to fit with that.
Among the meteorological features found in the new study include a band of clouds that has a striking scalloped shape and is positioned just south of Ecuador, and a swarm of small convective zones in northern Polar Regions of the planet, features never before seen in southern Polar Regions of Uranus.
There is still no clear explanation for the observed.
