First second-generation planet found orbiting white dwarf, formed from stellar debris
El DeberLO·2 days ago
Hubble and TESS data reveal a planet forming from the debris of a dead star, challenging the conventional model that planets only form during a star's early life. This is the first observed instance of a second-generation planet, indicating that planetary systems can regenerate after stellar death. The finding reshapes understanding of planetary evolution and the long-term fate of exoplanetary systems.
