Astronomers have long puzzled over a giant planet found orbiting a dead star in 2020. Now, data from NASA's James Webb Space Telescope (JWST) offers a potential explanation for the planet's improbable survival.
The planet's host star, after burning through its fuel, expanded into a red giant. This phase typically engulfs and destroys any nearby planets. Yet this gas giant somehow endured the stellar upheaval and later migrated closer to the remaining white dwarf.
JWST's infrared observations provide fresh clues. The telescope detected subtle signatures of debris disks and possible gravitational interactions that could have nudged the planet outward to safety before it spiraled back inward. These findings challenge existing models of planetary system evolution.
If confirmed, the scenario implies that some planets can survive their star's death throes and even change orbits dramatically. This reshapes our understanding of what happens to planetary systems as stars age.
No official peer-reviewed paper has been published yet. The team plans further JWST observations to strengthen the hypothesis.
