Nearby exoplanet has grown a tail 44 times longer than Earth — and it's acting like a giant 'stellar windsock'Researchers have detected a giant tail of gas leaking from an exoplanet near Earth. The giant structure, which is up to 350,000 miles long, is being blown away from the alien world by stellar gusts, allowing researchers to use it like a windsock.
