Cosmic Dust Identified As The Source Of Venus’ Enigmatic Lower Haze
Venus, often called Earth’s twin, is in fact a planet of extremes. Beneath its thick carbon dioxide atmosphere lie crushing surface temperatures and dense clouds of sulfuric acid. While the […]
Identifying Surface Degeneracies in Single-Visit Reflected Light Observations of Modern Earth using the Habitable Worlds Observatory
Characterizing the surface and atmosphere of Earth-like planets in reflected light is a key goal for upcoming direct imaging surveys.
Retrieving the Red Edge on Earth-like Planets with Heterogeneous Clouds and Surfaces
The detection and characterization of potentially habitable exoplanets is one of the chief goals of astrophysics for the coming decades. Imaging in reflected light is well suited for characterizing Earth-like […]
A Cloudy Fit To The Atmosphere of WASP-107 b
Context. WASP-107 b has been observed comprehensively by JWST in the near- and mid-IR bands, making it an ideal planet to probe the composition and internal dynamics. Recent analysis reveals […]
A Second Visit To Eps Ind Ab With JWST: New Photometry Confirms Ammonia And Suggests Thick Clouds In The Exoplanet Atmosphere Of The Closest Super-Jupiter
With JWST, we are directly imaging cold (~200-300K), solar-age giant exoplanets for the first time.
Hot And cloudy: High Temperature Clouds In Super-Earths And Sub-Neptunes
JWST observations provide for the first time evidence for an atmosphere on a rocky exoplanet – 55 Cnc e. The atmosphere of 55 Cnc e is hot with Teq>2000K and […]
JWST NIRSpec Finds No Clear Signs Of An Atmosphere On TOI-1685 b
Determining the prevalence of atmospheres on terrestrial planets is a core objective in exoplanetary science. While M dwarf systems offer a promising opportunity, conclusive observations of terrestrial atmospheres have remained […]
How To Spot Life In The Clouds On Other Worlds
An exoplanet with dense or even total cloud cover could help astronomers searching for signs of life beyond our planet.
Powerful Lightning On Venus Constrained By Atmospheric NO
Signs of lightning on Venus have long been sought, including by space missions and ground-based telescopes searching for optical flashes, plasma waves, or radio signatures.
