These extreme asymmetries mean that the interaction between Uranus’s magnetic field and the solar wind—charged particles constantly streaming out from the Sun in all directions—is also quirky. At Earth and other planets, the boundary where the solar wind slams into the planetary magnetic field and abruptly slows to form a turbulent shock wave, known as the bow shock, is relatively stable. But at Uranus, the bow shock is highly dynamic, changing shape and size throughout each Uranian day, like the expansion and contraction of breathing lungs.
