Astronomers discovered something strange in the magnetosphere of the Earth at a distance of about 160,000 km from our planet. Short -term bursts of energy were discovered, that is, choral waves, in that part of the magnetosphere where they had never seen them before what puzzled by scientists. The study published in Nature magazine, writes Smithsonian Magazine.

Office waves are often called " Office waves began to be called so, because they sound like birds singing if they convert them to audio signals.

Until now, astronomers discovered choral waves next to our planet at a distance of a maximum of 50,000 km. But with the help of the Magnetospheric Multiscale spacecraft, scientists have discovered choral waves at a distance of 160,000 km, which challenges the existing theory about how these phenomena arise.

Previously, scientists believed that choral waves can be created only near the dipole magnetic field, that is, fields with the northern and southern magnetic poles, like the ground. These waves were also found around other planets with magnetic fields, such as Saturn and Jupiter.

It is believed that the choral waves are caused by the instability of the plasma, which is outside its equilibrium state. This outrage can lead to the fact that the electrons will behave randomly, rotating along the spirals along the lines of the Earth’s magnetic field and produce radiation, which interacts with other electrons. The obtained choral waves move along the curved magnetic field from the pole to the pole, and create their " Below you can listen to how the discovered choral waves sound.

Recently discovered choral waves are in the very elongated and distant part of the earth's magnetosphere, which indicates another possible reason for their occurrence. Instead, they can be caused by frequency changes when moving in a magnetic field.

Scientists do not exclude a completely initial theory, but a new study involves the need for additional observations of choral waves. Now scientists intend to find more such phenomena in the same remote area of \u200b\u200bspace.

The results of the study are important for future cosmos studies, since choral waves have the ability to produce high-energy " Understanding these powerful particles can also help protect astronauts in manned missions.

Focus has already written that the proposed Dyson spheres found in the Milky Way are not related to extraterrestrial civilizations. Researchers have checked the best candidates for alien megastrusters around distant stars.
