"Scientists Stunned by Impossibly Large Exoplanet Discovery"

Penn State researchers have discovered an unusually massive planet, LHS 3154b, orbiting an ultracool dwarf star. This finding, contradicting current theories, prompts a reassessment of star and planet formation processes. The planet's mass is over 13 times that of Earth, while its host star, LHS 3154, has a mass significantly lower than the sun. The discovery challenges existing models of planet formation and raises questions about the formation of stars. The researchers used the Habitable Zone Planet Finder (HPF) instrument to detect the planet, which is the most massive known planet in a close orbit around an ultracool dwarf star.
