Story summary

NASA's James Webb Space Telescope (JWST) observed a carbon-rich disk around exoplanet CT Cha b, about 625 light-years from Earth, that may form moons.
The research team identified seven carbon-bearing molecules in the disk, contrasting with the chemistry of the surrounding star's disk.
The findings offer insights into early planetary and moon formation, tracing the solar system's development over 4 billion years ago, and were published in The Astrophysical Journal Letters.
