Outside the Solar system spotted radiance
Astrology was the first to see the Aurora Borealis outside the Solar system. It was observed for brown dwarf called LSR J1835 in the constellation Lyra at the distance of 18 light years to Earth.
As they say in the article published in the respected scientific journal Nature, this 1 case study auroras on a brown dwarf. It is about the dwarf LSR J1835, research for which was conducted using the VLA radio telescope, telescope Gale and Hawaii Keck Observatory.
Found glow similar to earth's Northern lights, only millions of times brighter. Also, it is more red and not green as on Earth. This is because on a brown dwarf charged particles interact with the hydrogen in the atmosphere of a celestial body. The green glow on the Ground is due to the interaction with the atoms of the air.
With all of this, scientists are not yet able to establish the nature of this phenomenon: a brown dwarf is not a planet, next to which there are no stars like our Sun, is able to create a stream of charged particles, coupled with the illumination of the upper layers of the atmospheres of planets have a magnetosphere, gives the Aurora Borealis, also known under the name Northern lights.
Previously it was known that auroras can be observed at all planets of the Solar system, not just on Earth. They are often, for example, on Venus or on Mars, were recorded on Pluto. Astrologers think that the Aurora on brown dwarfs can have an impact on what is happening on their surface processes, and plan to continue the study of this phenomenon.
