The aurora is the spectacular phenomenon in which the night sky in the polar regions is bathed in light and colors produced by the interaction of charged particles from space with the Earth's atmosphere.
Recently, the phenomenon has been observed on other planets in our solar system. In fact, the aurora on Jupiter is, according to scientists, 100 times more intense and bright than on Earth. For the first time, scientists announced that they have detected traces of the phenomenon on exoplanets, that is, planets that have been detected in other solar systems in our galaxy.
The discovery
Researchers at the University of Leicester in the UK, using the Low-Frequency Array telescope in the Netherlands, have detected a series of radio emissions that they believe are the product of auroras, and of high intensity on exoplanets.
The discovery is considered particularly important because studying the radio emissions of the aurora can reveal a series of data about an exoplanet: data about its magnetic field, its "relationship" with its parent star, whether it has satellites, and even the duration of day and night on it.
