Planet with a 5,63,000-km-long tail discovered outside Solar System

India Today  

Astrophysicists have made a groundbreaking discovery regarding the exoplanet WASP-69 b, revealing that it possesses a comet-like tail of gas extending approximately 5,63,000 kilometers. This tail is formed as the planet, a hot Jupiter located 160 light-years from Earth, loses its atmosphere due to intense radiation from its host star. The observed tail is at least seven times longer than the planet itself, providing a unique opportunity for scientists to study how stellar activity affects planetary atmospheres. As astronomers continue to study WASP-69 b and its tail, they hope to uncover more about how such phenomena occur across various exoplanets and their respective stellar environments.
