US EditionResearchers Find a Carbon-Rich Moon-Forming Disk Around Giant Exoplanet
The James Webb Space Telescope detected seven carbon-bearing molecules in a moon-forming disk around exoplanet CT Cha b, advancing knowledge of planetary system evolution.
- James Webb Space Telescope scientists reported the first direct measurements of a potential moon-forming disk around CT Cha b, with findings published in The Astrophysical Journal Letters.
- To understand why, researchers note observing planet and moon formation is fundamental, and the research team using the James Webb Space Telescope plans a comprehensive survey in the coming year.
- Using Webb's MIRI medium-resolution spectrograph, astronomers found seven carbon-bearing molecules including acetylene and benzene by analyzing archival Webb data with high-contrast methods.
- As an immediate outcome, the team says no moons were detected in the Webb data despite CT Cha b's carbon-rich circumplanetary disk, offering insight into moon formation and habitability.
- Chemically, the circumplanetary disk is carbon-rich while the circumstellar disk contains water but no carbon, indicating rapid chemical evolution over only 2 million years, and CT Cha b lies 625 light-years away about 496 AU from its star.

Moon-forming disk around massive planet offers insight into how the moons of gas giants might have formed
The NASA/ESA/CSA James Webb Space Telescope has provided the first direct measurements of the chemical and physical properties of a potential moon-forming disk encircling a large exoplanet. The carbon-rich disk surrounding the world called CT Cha B, which is located 625 light years away from Earth, is a possible construction yard for moons, although no moons are detected in the Webb data.

Webb peers into circumplanetary disk for first time
New Delhi: The James Webb Space Telescope has peered into a circumstellar disk for the first time. The disk is surrounding a large exoplanet designated as CT Cha b, with the host star around 625 lightyears from the Earth. CT Cha b is at a distance of about 496 astronomical units (AU) from its host star, with a single AU being the distance between the Earth and the Sun. The star is only two million years old, and is still growing from the infalli…
Webb Discovers Exomoon-Forming Circumplanetary Disk around Gas-Giant Exoplanet
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found the carbon-rich disk surrounding CT Cha b, a giant exoplanet around 620 light-years away from Earth in the constellation of Chamaeleon. The post Webb Discovers Exomoon-Forming Circumplanetary Disk around Gas-Giant Exoplanet appeared first on Sci.News: Breaking Science News.
