Astronomers using the James Webb telescope have discovered a planet orbiting a white dwarf—a dead star—revealing how planets can survive their host star's death. The discovery includes detection of aerosols and hydrocarbons in the planet's atmosphere, offering insights into planetary survival mechanisms and what Earth's fate might be when our sun dies.
·Webb telescope captured unprecedented atmospheric details of a planet around a white dwarf, including aerosols and hydrocarbons
·The planet survived its star's death and continues orbiting the stellar remnant
·Findings help scientists understand planetary survival and atmospheric composition around dead stars
·Research provides clues about Earth's distant future when the sun exhausts its fuel
·International team used spectroscopic analysis to detect chemical signatures in the surviving planet's atmosphere
