A Moist Exoplanet in the Neptune Desert

A Moist Exoplanet in the Neptune Desert

Water vapor detection of exoplanet atmospheres has been a hot topic. This scientific question is included in the first set of results published by JWST. But it’s even more difficult to detect the presence of water vapor on exoplanets in the Neptune desert. This year, researchers detected water vapor on TOI-674 b for the first time by analyzing atmospheric transmission spectrum. It’s very exciting. This discovery provides an important target for subsequent detection with higher precision by JWST.
