Auroras are not only in the world

Auroras - the result of the collision of charged particles from interstellar space with atoms in the atmosphere of a celestial body. On Earth, they can be observed in the polar regions. If you live in Russia, the most likely to see this beautiful natural phenomenon will appear in the vicinity of the Kola Peninsula.

Auroras occur not only on Earth. Astronomers were able to detect them in the atmosphere of the planets of the solar system - on Venus and Mars. On Mars, they, in spite of its name, there are poles apart in the equatorial regions, because the field of the planet is a residue once the full field.

Recently, an astrophysicist at the University of Leicester have discovered auroras outside our planetary system. As part of the study, the researchers used the model of the emergence of currents in the atmosphere of the gas giant, taking as an example Jupiter. It turned out that the model is suitable for brown dwarfs - celestial bodies representing intermediate class between stars and gas giants. The mass of these objects is sufficient to ensure that at some stage of their development within them the thermonuclear reaction, but this mass is not enough to maintain the "burning" hydrogen process energizes ordinary stars.

Thus, the researchers were able to learn more about the features of electromagnetic radiation of brown dwarfs - they should occur around the powerful lights. This is the first information of this kind for objects outside the solar system.
