A recent study reached a detailed three -dimensional drawing of the magnetic fields that permeate the Milky Way, which not only arises from heavenly bodies such as stars and planets, but also from the cosmic demolition and dust and hydrogen gas spread among the stars.
Although scientists realize the existence of these magnetic areas are old, the biggest challenge was in drawing a comprehensive map of the whole galaxy.
In contrast to the stars and planets, magnetic fields do not emit optical emissions independently, which makes their vision visually impossible through visual telescopes. To overcome this problem, scientists are looking for different mechanisms to find magnetic fields such as studying their interaction with charged particles or studying the change of the behavior of light through them.
In the case of stars and planets, magnetic fields are often planned by monitoring charged particles, such as ions that are traveling along the magnetic field lines, and the light is released in this process. It was the method in which the magnetic field of Jupiter was drawn for the first time, and the same applies to black holes.
But at the level of the galaxy and the widespread and widespread magnetic fields, it is more difficult to monitor the charged particles because they are weaker and more widespread, and thus the light issued is very dim. Instead, researchers use the polarized light technology that interacts with gas in different speeds based on its frequency, which results in a stable light beam that rotates and runs depending on the amount of ionized gas that passes it. And by virtue of the fact that the ionized gas is stuck in the magnetic fields, it is easy to draw the magnetic field in view of the various sources of light.
The polarized light is a light that fluctuates its waves in a specific direction, rather than the fluctuation randomly in different directions. This technique is used in several things such as polarized sunglasses that filter the light spreading from shiny things, and in water as it helps in getting rid of waves. As for space, there are many celestial bodies from which a stable light is emitted, such as the vibrant stars.
The recent study goes beyond that by combining the data coming from the Jaya spacecraft, as it provides a detailed map for the distribution and spread of stars and demolition in the local area of the Milky Way. With the inclusion of these data with the results of polarization of the spiral arm of the bow tower, the researchers enables to draw a detailed 3D map of the magnetic field of the galaxy.
The results have shown that the magnetic fields in the galaxy are not regularly spread, and do not fall along the level of the galaxy, but rather they take complex forms in many places between the stars. The researchers found that these magnetic fields can interact with and penetrate into the star incubators and affect the movement of gas and cosmic dust in it.
The results issued not only reveal how the new stars and their birth are formed, but also give a broader understanding of the structure and structure of galaxies and how they develop over time.
