An exoplanet near Earth, called WASP-69 b, has a gigantic tail stretching over 40 times the length of Earth.
The tail is composed of gas leaking from the exoplanet's atmosphere and is being blown by stellar winds, resembling a giant 'windsock'.
The exoplanet is a gas giant similar in size to Jupiter and orbits a star about 160 light-years away from Earth.
The discovery of the tail provides valuable insights into the formation and evolution of gas giants and allows scientists to study stellar winds in distant stars.
