JWST finds reflective atmosphere on ultra-hot planet TOI-561 b
Researchers used the James Webb Space Telescope to study the atmosphere of the ultra-short-period exoplanet TOI-561 b in a new paper published recently.
Previous observations suggested volatiles
Earlier studies detected hints that this world possessed an atmosphere containing water and carbon dioxide. A 2025 analysis based on limited data proposed the presence of these volatile compounds.
New study confirms reflection
The latest work examined the planet with greater detail using JWST instruments. The team published their findings in The Astronomical Journal to share results about the highly reflective nature of the gas layer.
Lead author from Canada
Samuel Boucher from the Université de Montréal led the investigation into this unique exoplanet. His team revisited the object to confirm the atmospheric properties detected in prior limited observations.
