Summary

Story summary

Astronomers have identified a new planet type called "soot worlds," primarily made of carbon-rich materials.
Research suggests soot, found in comets, may constitute significant portions of planets beyond a defined "soot line."
The James Webb Space Telescope is studying exoplanet atmospheres to distinguish between water and soot worlds, impacting habitability assessments.
Further atmospheric data and modeling are needed to evaluate the potential for life on these planets.
