Summary

Story summary

A study using the James Webb Space Telescope (JWST) revealed that GJ 1132 B, an Earth-sized planet, lacks a significant atmosphere.
This indicates that rocky planets near small stars may be inhospitable due to intense stellar radiation.
The JWST confirmed the absence of water and methane on GJ 1132 B, setting a new benchmark for exoplanet research.
Research suggests planets orbiting white dwarfs might support life, but face challenges like tidal heating.
The habitable zone around white dwarfs is much closer than that of the Sun, raising concerns about life viability.
