NASA Discovers Exoplanet with Massive Comet-Like Tail
The exoplanet WASP-69 b, a gas giant similar in size to Jupiter, has been found to have a 350,000-mile-long tail of gas, primarily helium, trailing behind it due to its close orbit around its star and the influence of stellar wind. This tail, acting like a 'stellar windsock,' provides insights into the interactions between the planet's atmosphere and stellar winds, offering a unique opportunity to study these phenomena. The discovery was confirmed using data from the W. M. Keck Observatory.
