Venus’ Atmospheric Chemistry and Cloud Characteristics Are Compatible with Venusian Life
Venus is Earth’s sister planet, with similar mass and density but an uninhabitably hot surface, an atmosphere with a water activity 50-100 times lower than anywhere on Earths’ surface, and […]

Two Warm Super-Earths Transiting the Nearby M Dwarf TOI-2095
We report the detection and validation of two planets orbiting TOI-2095 (TIC 235678745). The host star is a 3700K M1V dwarf with a high proper motion. The star lies at […]

Large Interferometer For Exoplanets (LIFE): X. Assessing the Impact of Clouds on Atmospheric Retrievals at Mid-Infrared Wavelengths with a Venus-Twin Exoplanet
The Large Interferometer For Exoplanets (LIFE) initiative aims to develop a space based mid-infrared (MIR) nulling interferometer to measure the thermal emission spectra of temperate terrestrial exoplanets.

The Earth-sized Exoplanet Next Door: The Venus Cloud Discontinuity in 2022
First identified in 2016 by JAXA’s Akatsuki mission, the discontinuity/disruption is a recurrent wave observed to propagate during decades at the deeper clouds of Venus (47–56 km above the surface), […]
