Space Hubble Telescope has detected a new secret dark storm on Neptune and gave a fresh look at a long-lived storm surrounded by a polar section north of Uranus, NASA said.
Like Earth, there are seasons in Ùranus and Neptune, who are likely to drive some of the features in their environments, according to the US space group.
However, the seasons are far beyond our planet, giving decades instead of months, NASA said in a statement.
The storm appeared during the most southerly planet summer, the fourth and the darkest darkest word captured by Hubble since 1993.
Two other dark storms were found by Voyager 2 spacecraft in 1989 when traveling with her; remote planet, NASA said.
Since then, Hubble has only been aware of the light of blue to find those delicious, emerging and rapidly evolving features.
An inspection was led by Andrew Hsu, a graduate student at the University of California, Berkeley in the USA, who perceives the dark places appear four to six years at different locations and after two years later.
Hubble sought the latest storm last September in the southern hemisphere of Neptune. The feature is about 6,800 miles away.
On the right side of the dark feature, a "bright cloud" is clear. Hubble has watched the clouds that come together with previous phones.
Like Jupiter's Great Red Spot, the dark phones are increasingly involved in the face of their face; chiclonics and they think they are Excavating material from deeper levels in the ice giant's atmosphere.
Hubble surveys show as soon as 2016, that the department has more room-based activity; appear on the appearance of a flash.
The images show that the watchphones can be deeper in the Neptune flame, and they will only see it when the top of the storm rises.
The image of Uranus, similar to the Neptune's image, features a key feature: a blurred stormy blow across its north pole.
Scientists believe that this new feature is the result of the special Uranus encirclement. Unlike all other planets in the solar system, Ùranus is covered close to it.
Due to this wilderness, in the summer of the world the Sun appears almost directly on its face; north pole and has never been a situation.
