Earth-Sized Exoplanet Discovered Orbiting Ultracool Dwarf Star

SPECULOOS-3 b, located 55 light-years away, presents unique research opportunities despite its harsh conditions.

  • SPECULOOS-3 b orbits its star every 17 hours and is likely tidally locked, with one side perpetually in daylight.
  • The planet's host star is cooler and dimmer than our Sun, affecting the planet's potential habitability.
  • Researchers believe the planet lacks an atmosphere due to intense stellar radiation.
  • The discovery was made by the SPECULOOS project, which aims to find Earth-like planets around dim stars.
  • Future studies with the James Webb Space Telescope could reveal more about the planet's surface and composition.
