Venus (Probably) Ate Its Moon
[UC Riverside] Scientists have long speculated why Venus, with a similar size, mass, and structure to Earth, doesn’t have a moon. New UC Riverside research shows it’s because our hungry […]

The Venus Benchmark: Resolving Degeneracies in Terrestrial Exoplanet Spectra with DAVINCI
[astro-ph.EP]. The characterization of terrestrial exoplanets with thick, CO2-dominated atmospheres via transmission and emission spectroscopy is limited by degeneracies between atmospheric composition, cloud structure, and surface conditions.

Study: Peptides Can Form Well-defined Structures In Harsh, Venus-like Conditions
[MIT] When exploring solar system bodies for signs of past or present life, scientists have mainly focused on planets that have (or had) a liquid surface similar to Earth’s. However, […]

Study On The Venusian Atmospheric Thermal Structure: A Comparative Analysis Between VEX/Akatsuki And Venus-GRAM/VCD
[astro-ph.EP] We investigate the thermal structure of the Venusian middle atmosphere between 45 and 80 km using radio occultation (RO) measurements from Venus Express and Akatsuki spanning 2006-2024.
![HZ and planetary orbits in the GJ 12 system. The extent of the HZ is shown in green, where light green and dark green indicate the CHZ and OHZ, respectively. The solid line shows the orbit with the nominal eccentricity of 0.24, and the dashed lines represent 1σ boundaries (Turner et al. 2026). The scale of the figure is 0.2 AU along each side with a 0.02 AU grid.-- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/08/The-Tidal-.png?resize=1200%2C712&ssl=1)

Atmospheres As Habitats
[Astrobiology (Journal)]. The potential of planetary atmospheres as habitats is understudied and likely underestimated. Although planetary atmospheres can provide the fundamental physical, chemical, and energetic requirements for life, they also […]
