science ๐ Exoplanet sends first-ever detected radio signal
Astronomers have detected a radio signal originating directly from an exoplanet for the very first time. This groundbreaking discovery was made by researchers from Harvard & Smithsonian and the University of Oregon, who pinpointed the source. The detection occurred in the Beta Pictoris system, which is located 63.4 light-years away from Earth. The signal is actually from the exoplanet's aurora, suggesting it has a strong magnetic field. This marks the first direct measurement of an exoplanet's magnetic field strength. ๐ฐ๏ธ
