Bad news for alien life? Earth-size planets may be less common than we thought

SMRTR summary

Astronomers found that up to 200 exoplanets may be larger than initially thought due to light contamination from nearby stars, affecting the search for alien life. This suggests fewer Earth-like planets have been discovered, with many potentially being ocean worlds or small gas giants. The findings impact prioritization for James Webb Space Telescope observations and our understanding of water worlds in the galaxy.
