The lights hold clues to the composition of the planet’s magnetic field and how this field works.

Peter Delamere, a professor at the University of Alaska Fairbanks Geophysical Institute, is part of an international team of 13 researchers who made the key discovery related to the aurora on the largest planet in our solar system.

Scientists have found that the magnetic field lines emanating from the poles of Jupiter are in fact closed, and not open, as previously thought.

Open (or open) lines are those that emanate from the planet, but go into space, and do not reunite with lines coming out of the same place on the opposite side of the planet. On Earth, for example, the aurora appears on closed lines in an area called the auroral ring. It is located in high latitudes near each end of the planet’s magnetic axis.

Внутри авроральной зоны на Земле и многих других планетах нашей Солнечной системы, есть место, называемое полярной шапкой. В нем сияния формируются редко из-за незамкнутых линий магнитного поля. У Юпитера тоже есть полярная шапка, но сияния там появляются часто. Этот факт долго не давал покоя ученым — было неизвестно, почему так происходит. Новое исследование наконец-то позволило это выяснить.
