Uranus, the seventh planet from the Sun and the third largest in the Solar System, is in continuous processes of change. When the Voyager probe flew over it in 1986, what he discovered was a planet without little activity. For this reason, astronomers began to call it "the black hole of the Solar System."
But Uranus changed and keeps changing. In 2012, an international team of scientists discovered the strong wind gusts that blow on the planet. The images that revealed it were obtained thanks to a new technique used at the Keck Observatory in Hawaii.
The studies revealed that Uranus has a thick atmosphere formed by hydrogen, helium and methane. Winds blow on its surface, mainly, from east to west, and at speeds exceeding 900 kilometers per hour. And all this despite the small amounts of energy available to drive them.
Other more recent studies show that these strong winds are only found in a relatively thin layer of Uranus, a small area no more than 1,100 kilometers deep.
The climate of Uranus is strange, and its atmosphere is very similar to that of Neptune. Its temperatures drop enough to freeze methane, around -180 degrees Celsius. But scientists warn that Uranus is changing, and they don't expect the current surface situation to remain as it is.
