On Earth received the first data on Jupiter from the probe Juno, launched in 2011 and flew to the planet in 2016th. The most important discovery was that the magnetic field of the planet was much more powerful than the astronomers believed earlier. The value of the magnetic field is 7.766 Gauss, which is almost twice as strong as previously thought and approximately 10 times stronger than that of the Earth. In some places, the magnetic field of the giant is stronger, in some weaker, scientists report.
Also, Juno sent to the Earth pictures of Jupiter's poles with bright spots, which are powerful cyclones. At the North Pole, their diameter is 1.4 thousand kilometers, and on the south pole – 1 thousand.
Juno managed to fix the rings (not as powerful as Saturn's, but they also have Jupiter) and record "music" of Jupiter, which appear as a result of the interaction of the magnetic field with the solar wind.
