exoplanets

Researchers have reported detecting a direct radio signal from a planet outside the solar system for the first time. The announcement is being widely shared as a potential milestone in the study of exoplanets, since radio emissions have previously been observed mainly from stars and other cosmic objects rather than from planets themselves. Details about which planet was involved and how the signal was confirmed have not yet been widely reported.

Harvard scientists report detecting a radio signal apparently coming directly from a planet outside the solar system. If confirmed, it would be a rare example of a radio emission traced to an exoplanet, possibly generated by the planet's magnetic field interacting with its star. Astronomers say such detections could open a new way to study distant planets, though further observations are needed to verify the signal's origin.
