Overview

• 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.
