Altered Cosmic Organics As Venus’ Ultraviolet Absorbers
[astro-ph.EP] Venus’ ultraviolet (UV) absorbers significantly contribute to the atmosphere’s energy budget. However, the composition of these absorbers remains a mystery.

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 […]

Development Of A Data Retrieval Algorithm For Venus Nephelometry In Preparation For The Rocket Lab Mission To Venus
[Science Direct] The Rocket Lab Mission to Venus (RLMV) will carry a single primary instrument, the Autofluorescence Nephelometer (AFN), to interpret atmospheric particle properties from light-scattering measurements. This process is […]

Venus: Dead? Far From It
[ETH Zurich] Simulations conducted by researchers at ETH Zurich suggest a strong likelihood that Venus’s rift valleys are still geologically active rather than being mere relics of a bygone era, […]
![Numerical computations corresponding to the candidate pattern in the H–alpha filter (λ0 = 656 nm), for the total flux (left) and the polarized flux (right). The background polarization signal has been subtracted from the latter. The decrease in spatial resolution due to the Earth’s atmosphere is not included. The planetary atmosphere is assumed to be horizontally homogeneous except for the gas density variations. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/Planet-wide.png?resize=1200%2C711&ssl=1)

Planet-wide, Concentric Density Waves in Venus’s Upper Atmosphere Revealed through Polarimetry?
[astro-ph.EP] We report observations of faint (10−6), concentric, planet-wide rings in the polarized flux of sunlight that is reflected by Venus, obtained during a serendipitous, 36-minute run in 2010, with […]

Coupled AtmospHere Interior modeL Intercomparison (CHILI). I. Evolutionary Modelling — Primordial Magma Oceans of Earth and Venus
[astro-ph.EP] Earth and Venus represent two evolutionary outcomes arising from initially molten ‘magma ocean’ periods, followed by lifetimes of chemical and geophysical divergence. Their physics is common to all rocky […]

A Panspermia Origin For Venus Cloud Life
[USRA] Panspermia is the idea that life can originate on one planetary body and then be transferred to other bodies. Impacts are often the suggested method for transfer, as they […]
