Astronomers capture the futuristic magnetic field of the galaxy NGC 4217


When exploring deep space, astronomersencounter unusual, colorful phenomena that make it possible to assess the development and formation of distant galaxies. The survey of the magnetic field of the galaxy NGC 4217, carried out by the Dutch and American astrophysicists, in the spectrum invisible to the human eye made it possible to estimate not only the strength of the galaxy's magnetic field, but also to determine its orientation.

Galaxy NGC 4217 is located at 67 millionlight years away from the solar system and is classified as a spiral galaxy. Astronomers also know the orientation of the galaxy, which is turned sideways towards us. The magnetic field generated by NGC 4217 extends over 22.5 thousand light years.

When detecting the magnetic fields of galaxiesused synchrotron radiation generated by the contact of cosmic ray electrons (CRE) with the magnetic field itself. As a result, it was revealed that the magnetic field of NGC 4217 has an X-shape.

A more detailed study of the magnetic field wasdiscovered two giant "superbubbles", which may indicate the place of death or birth of stars. Also in the field of NGC 4217, giant magnetic loops are recorded, the origin of which cannot be explained by modern science. Scientists noted that the total field strength is relatively small and amounted to 0.9 microgauss, while the earth's field strength is 0.5 gauss.

At present, the main hypothesis aboutthe origin of the magnetic fields of space objects is based on the presence of an electrically conductive liquid that converts kinetic energy into magnetic field energy. So for the Earth it is a liquid molten core, for the Sun it is plasma. However, what generates the magnetic fields of galaxies is not yet reliably known.

On this occasion, many hypotheses have been put forward. One theory states that the movement of matter can be caused by a supernova explosion and the Coriolis force, as a result of which the compressing gas leads to the creation of a turbulent inhomogeneous system.
