This Telescope Might Be Able to See Aliens in Exoplanets
In France, astronomers have unveiled a radio telescope that can show exactly what's going on inside an exoplanet. The telescope searches for enhanced beam-like radio signals when a planet's magnetic field interacts with wind charged particles coming from its stars.
It's suspected that a magnetic field may be needed for a planet to harbor life because magnetic fields protect a planet's surface from cosmic rays. Also, magnetic fields are able to prevent the particles from extinguishing a planet's vital atmosphere.
In the mid-1950s, radio bursts were detected from Jupiter. Even though the signals of Jupiter are strong, they're still too weak to be seen at light-year distances. However; the exoplanets detected so far are "hot Jupiters" which means that they are gas giants too.
And the kind of a planet which is affected by a strong stellar-wind would offer more electrons to be enhanced by the planet's magnetosphere into a signal which could be a million times stronger than Jupiter's.
So, that is the reason why we aren't able to search for life in our solar system and it's easier to search for it in exoplanets.
It's shown on the video that when a star emits a powerful blast, a planet with a magnetic field survives the blast, while the one with no magnetic field cannot.
Thus, by detecting these radio signals, new life in the distant worlds can be found.
