In 1989, the Voyager 2 probe discovered the first proof of existence Auror in NeptuneThe field, however, has not yet been confirmed that this is a reality. A photograph was needed, and this was necessary for the rock -star of space telescopes. He James Webb.
In 2023, this took several photographs and measurements, with which it was possible to better know the atmosphere of the most further of the planets of the solar system (if we retain the thesis that Pluto is not). Now a new study published in Natural astronomy a team led from University of NorthumbriaIt reveals some images on which the aurors clearly see in Neptune, which have not yet been recorded. He did this, first of all, for his great ability to measure in an infrared position.
In addition to giving us precious images, worthy of the best of Savapantallas, this study is very useful because it helps us to find out better than one of the least famous planets of the solar system. And logically, because this is another proof of everything that James Webb can achieve, without even approaching the planet that you want to investigate.
What are Aurors in Neptune?
Aurors in Neptune have the same origin as the land and other planets, such as Jupiter, Saturn or Uranus.
They happen when charged particles from Solar activity They interact with atmosphere atoms. It produces excitation mentioned atoms, from -s The movement of electrons Inside, moving from the layer in which they are in superiority. The result is usually radiation of energy in the form of cauliflower, which depends on the atom that is excited. For example, greenish, reddish or purple aurors prevail on Earth. The first two shades are associated with oxygen, while the third is associated with the excitation of nitrogen atoms.
In the case of the Auros of Neptune, who captured James Webb, they look at curious turquoise tones. We know that the composition of its atmosphere is mainly hydrogen, helium and methane, and that the latter is responsible for the characteristic blue color of the planet. The excitement of some of these atoms, especially Attic hydrogen, is what leads to aurors.
Now, if there is something, which is very striking with Neptune Auroras This is that, unlike the Earth and other planets, they are no more intense in the poles. Vice versa. Most concentrate on medium latitudes.
What is it?
On Earth, aurors concentrate on the poles, because it is where The magnetic field is weakerThe field when charged particles from the sun reach us, usually the magnetic field transfers them to points where it no longer has such a great intensity. They said in very conversational methods and, in order to get an idea, they slipped like a slide until you find a place for entering. And this place is usually the northern or southern pole. That’s why we are always talking about Northern and southern radiance.
When solar activity is very intense, they can be further from the poles, as happened several months ago. The reason is that loaded particles are able to cross the more intense areas of the magnetic field. But all this is something more exceptional.
In Neptune, his magnetic field is inclined 47º relative to the axis of rotation. This makes Aurors not move towards the poles, but in the fact that they fall directly into the center.
Of course, James Webb does not stop giving us wonderful images, and they will not be an exception.
