NASA announced that the James Webb Space Telescope has discovered a new exoplanet orbiting within the habitable zone of its host star, making it one of the most promising candidates for further study in the search for life beyond Earth.

The planet, designated TOI-7042 b, is approximately 1.2 times the size of Earth and orbits a red dwarf star about 130 light-years away. Initial atmospheric analysis suggests the presence of water vapor and carbon dioxide.

Scientists said the findings are preliminary but encouraging. Follow-up observations will be needed to determine whether the planet has a stable atmosphere and conditions potentially suitable for life.

The discovery underscores the Webb telescope transformative impact on exoplanet research since it began science operations two years ago. NASA said the telescope has now identified over 50 candidate exoplanets.
