Life After Stellar Death: JWST Confirms Atmosphere on White Dwarf Planet

The first detection of an atmosphere on a planet orbiting a white dwarf (WD 1856 b) shatters the assumption that stellar death ends planetary habitability. This discovery, confirmed by JWST in July 2026, extends the potential habitable epoch by billions of years and forces a radical recalibration of astrobiological models across the galactic timeline [1][2].
