Liputan6.com, Jakarta – In 1781, the German-born English astronomer viz William Herschel making Uranus the first planet discovered with the help of a telescope.
This planet, nicknamed the Cold Planet, is the third largest in our solar system.
However, this planet still has a mystery. What was studied hundreds of years ago was not all on target.
Most know about it Uranus obtained when NASA’s robotic spacecraft Voyager 2 made a five-day flight in 1986, cited from page Japan todayWednesday (13/11/2024).
But scientists have now discovered that the observations were made in unusual circumstances, namely a very strong solar wind event.
The impact led to false ideas about Uranus, and in particular its magnetic field.
The solar wind is a high-speed stream of charged particles emanating from the Sun.
The researchers looked at eight months of data from around the time of the Voyager 2 mission and found that the solar wind encountered Uranus just days after the solar wind destroyed the magnetosphere.
Another effect of the solar wind creates a protective magnetic bubble of the planet about 20% of its normal size.
“We found that the solar winds that were present during the flight occurred only 4 percent of the time. The flight occurred at the highest level of solar wind intensity over the entire eight months, “said space physicist Jamie Jasinski of NASA’s Jet Propulsion Laboratory. .
“We would have seen a much larger magnetosphere if Voyager 2 had arrived a week earlier,” Jasinski said.
Such a trip would likely show that Uranus’ magnetosphere is similar to that of Jupiter, Saturn and Neptune, the other giant planets of the solar system, the researchers said.
