Newly Discovered Exoplanet Defies Expectations by Retaining Atmosphere

The planet, nicknamed Phoenix, challenges current theories about atmospheric loss in extreme environments near aging stars.

Phoenix orbits its red giant star at a perilously close distance, yet maintains a puffy atmosphere.
This discovery suggests planetary atmospheres may be more resilient than previously thought.
Phoenix's survival could offer insights into Earth's future as the Sun evolves into a red giant.
Researchers utilized data from NASA's TESS and Keck Observatory to study the planet's unique properties.
The findings prompt a reevaluation of how planets and their atmospheres evolve near dying stars.
