Aurorae spotted in Jupiter sparks interest of scientists
Aurorae: Polaris, Borealis, and Australis
Aurorae (also known as natural light displays always) spark the interest of scientists, should they be seen here on Earth or if they occur in other space bodies. The reason for this is because these natural light displays hold a lot of information about what composes the magnetic field of a planet and this specific field functions.
A recent spotting of natural light displays in Jupiter conjured up studies about this phenomenon. One of these studies has been issued out in Science Advances with the title “How Jupiter’s unusual magnetospheric topology structures its aurora.”
This study is focused on studying the magnetosphere of Jupiter, analyzing the global magnetohydrodynamic model of the planet. Moreover, this study explored the polar caps of Jupiter.
What this study proved is that the polar caps of Jupiter wound around the magnetic field lines that are closed. In addition to this, because of these polar caps, these magnetic field lines do not open completely. This is a usual occurrence in other planetary bodies.
The Inside Scoop on The Polar Caps of Jupiter and Its Auroras
To show the difference between the concepts of auroras and magnetic fields in our very planet Earth and Jupiter, one must know how it goes on Earth.
Here on Earth, aurora light displays show themselves in magnetic field lines that are closed. These circle around a zone that is labeled as the auroral oval. This is considered to be the high-latitude ring that is found close to the tips of the magnetic axes of Earth.
Within that ring is the polar cap, an empty spot wherein magnetic field lines are dispersed throughout. Because of this, aurora light displays seldom appear.
One can compare this to an electrical circuit in one’s home that is not complete, with the concept of an incomplete circuit not producing lights.
For Jupiter, on the other hand, aurorae is still present even with a setup like that. This intrigued scientists and astronomers.
The Juno spacecraft by NASA is an assigned spacecraft to explore Jupiter. When it landed on Jupiter, the planet’s polar cap and the aurorae are some of the images that were recorded by Juno.
However, the images seen by Juno could not appease the confusion of scientists about the concept of open and closed lines, consequently baffling researchers and scientists.
Amazing phenomena just like auroras are always so breathtaking to witness, considering how it is usually a once in a lifetime experience to observe. Alas, it is rare for people to come across this kind of surreal moment. To be able to witness such moments in the comforts of one’s home, one may do so by checking in on Youtube or by watching it through TV channels on space exploration in SAMSUNG 65-inch Class Curved UHD TU-8300 Series.
