Astronomers using the James Webb Space Telescope (JWST) have detected the first planet seen orbiting a dead star, offering new insights into how planets evolve during the final stages of a star's life.
The James Webb Space Telescope's observations of the exoplanet, named WD 1856+534 b, also confirm it is the coldest exoplanet to date, which could pave the way for the first detailed atmospheric studies of gas giant exoplanets and help us contextualize our solar system on a cosmic scale.
