NASA's TESS telescope has discovered a potentially habitable exoplanet named Gliese 12b, located just 40 light-years away.

Gliese 12b is slightly smaller than Earth and has a surface temperature of 42 degrees Celsius, suitable for liquid water.

Scientists believe this discovery could provide crucial insights into the pathways for planetary habitability.

Researchers plan to use the James Webb Space Telescope to analyze Gliese 12b's atmosphere and its potential for supporting life.

This finding, facilitated by NASA's Transiting Exoplanet Survey Satellite, may offer valuable information on habitable exoplanets and the evolution of our solar system.
