"Discovery: Exoplanet WASP-69 b's Enormous 350,000-Mile Tail"

Astronomers have discovered the gas giant exoplanet WASP-69b, located 160 light-years away, with a comet-like tail seven times longer than the planet itself. The tail is formed as the planet's atmosphere is stripped away due to its close proximity to its star, and observations from the WM Keck Observatory in Hawaii have provided valuable insights into the planet's atmospheric mass-loss in real time. Despite losing large amounts of hydrogen and helium, the massive exoplanet is not in danger of losing its entire atmosphere within the star's lifetime.

"Discovery: Distant Planet Found with 350,000-Mile-Long Tail"

Astronomers have discovered exoplanet WASP-69B, a hot Jupiter with a 350,000-mile-long comet-like tail formed by its leaking atmosphere caught in stellar winds. The planet sheds up to 200,000 tons of mass per second, yet researchers believe it will retain most of its atmosphere throughout its star's lifetime. This unique observation provides insight into planetary formation and could lead to new discoveries in space exploration.

"Scientists Discover Massive 350,000-Mile Comet-Like Tail on Distant Exoplanet"

The exoplanet WASP-69b, located 160 light-years from Earth, is trailing a massive comet-like tail approximately 350,000 miles long as its atmosphere is blown off by its parent star. New observations from the Keck Observatory in Hawaii reveal that the planet's atmosphere is escaping at a rate of 200,000 tons per second, forming an expansive tail not previously seen. This discovery provides a rare opportunity to study atmospheric mass-loss in real time and understand the critical physics that shape thousands of other planets.

"Scientists Discover Massive 350,000-Mile-Long Comet-Like Tail on Distant Exoplanet"

Astronomers have discovered that the exoplanet WASP-69b, located 160 light-years away, has a 350,000-mile-long tail of helium gas trailing behind it, resembling a comet's tail. This "Hot Jupiter" planet, slightly larger than Jupiter and very close to its star, is an eccentric addition to the known exoplanets and offers scientists an opportunity to study how planets lose their atmospheres.

"Massive 350,000-Mile-Long Comet-Like Tail Discovered on Distant Exoplanet"

Astronomers have discovered that the exoplanet WASP-69b, located 160 light-years away, has a 350,000-mile-long tail of helium gas trailing behind it, resembling a comet's tail. This "Hot Jupiter" planet, slightly larger than Jupiter and very close to its star, exhibits an extravagant tail due to its atmosphere heating to extreme temperatures and being accelerated into space by the star's intense radiation. The discovery sheds light on how planets lose their atmospheres and provides insight into the behavior of Hot Jupiters.
