in the world northern Lights and southern lights in other words auroras it’s pretty awesome. However, our planet is not the only place in the solar system where these events can take place.

On every planet except some moons of Mercury and Jupiter and even a comet, sometimes in invisible wavelengths atmospheric a brilliance detected. But that’s where it gets interesting Hymn† The red planet is known for its missing global magnetic field, which is a component and plays a critical role in the formation of aurora elsewhere. However, this does not mean that Mars is completely free of magnetism. In some parts of the Earth’s crust, especially in the southern hemisphere, regions of localized magnetic fields are sprouting. A new study finds that these small, localized magnetic fields are used to produce Mars’ discrete ultraviolet northern lights. with the solar wind turned out they interacted in interesting ways.

How solar wind affects auroras on Mars revealed

University of Iowa physicist and astronomer Zachary Girazian said:We conducted the first detailed study to look at how solar wind conditions affect auroras on Mars.said.

giraffe, “Our main finding is that within the region of the strong crustal field, the rate of aurora formation largely depends on the direction of the solar wind’s magnetic field. Outside the strong crustal region, the rate of formation is largely dependent on the dynamic pressure of the solar wind.He explained why the Northern Lights appeared on Mars.

Auroras are formed the same way on Earth and in space.

The two largest examples of auroras on Earth are aurora borealis and aurora borealis. There is pretty clear scientific evidence for how these two auroras were formed. These lights are produced when particles from the solar wind collide with Earth’s magnetosphere. They then rain down to the upper atmosphere and accelerate along magnetic field lines to higher latitudes. They work together with atmospheric particles to produce lights that dance, twinkle in the sky.

Evidence emerging from the study shows that the phenomena occur in similar ways in other objects. For example, JupiterThe powerful, sustained Northern Lights are revealed by the massive planet’s complex magnetic field.

But Mars’ global magnetic field was disrupted quite early in the planet’s history, leaving only the magnetized minerals in the crust. magnetism left the pieces. Ultraviolet images of Mars at night revealed that northern lights tend to form near these magnetic fields in the Earth’s crust.

The solar wind is not the only cause of northern lights on Mars!

Girazian and his team’s work takes into account the conditions of the solar wind. At the same time, the team has been collecting ultraviolet images of the red planet since 2014.MAVEN) also analyzed data from the spacecraft.

The pressure of the solar wind seems to play little role in the brightness of these northern lights, according to the team’s work. This led Girazian and his team to think that space weather events such as coronal mass ejections, in which masses of charged particles are ejected from the sun and associated with higher solar wind pressures, could trigger the northern lights on Mars.

Within the magnetic field regions of the Earth’s crust, the direction of the magnetic field and solar wind appear to play an important role in the formation of the northern lights on Mars. In certain directions, the solar wind appears to be suitable for magnetic reconnection events or particle acceleration needed to produce ultraviolet radiation.

These results reveal new insights into how the northern lights may appear on a planet stripped of the global magnetic field from interactions with the solar wind, the researchers said.
