JWST May Be Missing Water Hidden Deep Within Mini-Neptune Worlds
Sub-Neptune exoplanets, exoplanets that are slightly smaller than Neptune, have been designated as the most common type of planet in the Milky Way Galaxy based on their vast discovery numbers, totaling almost 3,300 out of the more than 6,300 confirmed exoplanets to date. Despite these numbers, the characteristics of sub-Neptunes remain relatively unknown. This is primarily due to our own solar system not having its own sub-Neptune to use as an a…
Researchers at the University of Chicago have discovered that the James Webb telescope may not be able to detect water on exoplanets classified as mini-Neptunes, such as TOI-270 d. The study, published in The Astrophysical Journal, suggests that these planets may harbor more water than previously thought, due to atmospheric characteristics that hinder observation. Sub-Neptunes: characteristics and observation challenges Mini-Neptunes are exoplan…
