An enigmatic radio signal from the direction of Proxima Centauri, the Sun’s nearest stellar neighbor, has set the internet ablaze with rumor and speculation. It could turn out to be the real deal — a calling card from another civilization. More likely, it’s much ado about nothing.
The discovery was leaked to the British newspaper The Guardian, which reported the story December 18. Researchers subsequently granted interviews to Scientific American and National Geographic. Since then, however, the discovery team has remained tight-lipped about the signal.
