Scientists have realized that the Uranus magnetic field is connected every day like a on and off light as the planet spins. Researchers at the Georgia Institute of Technology in the United States They were at the discovery in the Voyager 2 database NASA’s spacecraft, the last in 1986 turning the Uranus.
“The magnetosphere is” open “in the orientation so that the solar wind can flow into the magnetosphere and then close and create a shield against the sun’s wind and direct it from the planets,” the researchers said.
It is very different from Earth’s magnetosphere, which overlaps normally only between open and closed in response to changes in the Sun’s wind. From the same orientation of Earth’s magnetosphere Earth always magnetic fields that attach to the ubiquitous solar wind should change direction for reshape Earth Field from closed to face. This often occurs in strong solar storms.

To be focused and tilted about 60 degrees from its axis, these features make the magnetic field fall asymmetrically in relation to the direction of the Sun’s wind, while the ice giant completes its full rotation for 17.24 hours.
Instead of the solar wind that dictates the switch of this kind on Earth, it causes swift changes in Uranium rotation in the field of strength and orientation to the open-close-open-close-stage periodic falls that fall through the solar wind, according to the researchers.
“Uranium is a geometric nightmare, a magnetic field is very blurred very quickly because the child pushed the hill above the heel down,” said Carol Paty Associate Professor at the Georgia Institute of Technology.
“If the solar wind magnetizes suitably fortunately this field can reconnect and Uranus magnetosphere goes from openly closed every day to open,” he added.
Reconnection of magnetic field is a phenomenon in the entire solar system. This is one of the reasons for the earth auroras. The researchers used numerical models to simulate the global magnetosphere of the planet and to provide a suitable site to connect.
They joined Voyager 2 during his five-day booklet of collected data in 1986. This is the only time when he turns space ship.
“Perhaps what we see in Uranus and Neptune is the norm for the planet: a very unique magnetosphere and less-aligned magnetic fields,” said Cao Xin with the Georgia Institute of Technology.
“To understand how this complex magnetosphere protects exoplanet star radiation helps this newly discovered world’s habitability is essential,” said Cao.
