Discovery of Rocky Outer Planet Challenges Planet Formation Theories
Astronomers have discovered a planetary system around the red dwarf star LHS 1903 that challenges traditional planet formation theories. This system features an unusual 'inside-out' arrangement where a rocky planet is located beyond its gaseous neighbors, contradicting existing models. The discovery was made by a team including Dr. Thomas Wilson from the University of Warwick, with contributions from NASA and the European Space Agency. The findings were published on February 13, 2026, and reported from Lewisville, Texas, United States. This unique planetary configuration has prompted scientists to reconsider and propose new mechanisms for how such systems might form.
