New Earth-Sized Planet Discovered Orbiting Ultra-Cool Dwarf Star

SPECULOOS-3b, found 55 light-years away, offers insights despite its harsh, uninhabitable conditions

Astronomers detected SPECULOOS-3b using the SPECULOOS telescope network, focusing on ultracool dwarf stars.
The exoplanet completes an orbit around its star in just 17 hours, with one side perpetually facing the star.
SPECULOOS-3b is bombarded with intense radiation, making it unlikely to support an atmosphere or life.
The discovery underscores the capability of the SPECULOOS network to find Earth-sized planets around small stars.
Future observations with the James Webb Space Telescope aim to uncover more details about SPECULOOS-3b's composition.
