LHS 3844 b: The Dead Rock That Shows Why Earth-Sized Does Not Mean Earth-Like
JWST has given astronomers one of the clearest looks yet at the surface of a rocky exoplanet, LHS 3844 b, also called Kuaʻkua. The result is not alien life, not oxygen, and not a second Earth. It is a dark, hot, likely airless super-Earth orbiting a red dwarf star every 11 hours, with a basalt-like or space-weathered surface and no detectable atmosphere. The discovery matters because it shows that the exoplanet era is moving from planet detection into planet interpretation, and it forces a harder lesson: Earth-sized does not mean Earth-like.

K2-18 b is not proof of alien life, but it may be one of the most important exoplanets ever studied because it shows how the search for life is shifting from imagination to contested atmospheric chemistry. JWST has detected methane and carbon dioxide in its atmosphere, while disputed DMS and DMDS claims show how difficult it will be to separate biology, chemistry, instrument noise, media hype, and human hope.
