Astronomers have discovered Gliese 12b, a potentially habitable Earth-like exoplanet located 40 light-years away in Pisces constellation. Orbiting a cool red dwarf star, Gliese 12b, sized between Earth and Venus, lies within the star's habitable zone, where liquid water might exist. Despite its 12.8-day orbit, its estimated surface temperature of 42°C hints at potentially life suitable conditions.
