Radio signals from an exoplanet have been detected for the first time

While astronomers discover many exoplanets every year, some of which are surprising, they have now detected signals from an exoplanet for the first time. But there is no reason to believe that these signals are linked to an extraterrestrial civilization. This phenomenon is entirely natural and was caused by auroras in the upper atmosphere of this celestial object. 

In fact, astronomers had already detected radio emissions in the past. However, they were unable to determine whether the signals came from an exoplanet or a star. But in the case of the gas giant β Pictoris b, the situation is different. 

A team of astronomers led by Kevin N. Ortiz Ceballos used the MeerKAT radio telescope, located in South Africa, to study the β Pictoris system, which is about 64 light-years from Earth. During their study, they detected faint bursts of radio signals coming from this system. By precisely locating the source of these signals, they discovered that they originated from the exoplanet β Pictoris b. 

But that's not all, because these bursts have allowed astronomers to learn more about this exoplanet. Thus, the magnetic field of this young gas giant is estimated to be at least 1,250 gauss at the emission site. By way of comparison, this is much stronger than that of Jupiter.
