Astronomers Uncover Secrets of a Giant Planet Orbiting a Dead Star

Recent observations have shed light on the unusual survival of WD 1856 b, a Jupiter-sized exoplanet orbiting a white dwarf star. Located 80 light-years away, this planet completes an orbit every 34 hours, much closer to its star than Earth is to the Sun. The findings may provide insights into the future of our solar system's gas giants, like Jupiter and Saturn, when the Sun eventually dies in about 5 billion years. Researchers utilized the James Webb Space Telescope to gather data on WD 1856 b's atmosphere, revealing unexpected characteristics and suggesting that massive planets can endure the violent death of their host stars in ways previously thought impossible.

Key Details: • WD 1856 b is located 80 light-years from Earth and orbits its star every 34 hours. • The planet's mass is estimated to be between four and eleven times that of Jupiter. • Observations were challenging due to the brief duration of the planet's transit, lasting only 8 minutes. • The research indicates the planet may have migrated closer to its star after its host's death, with implications for the future of our solar system.
