Multiple controversial scenarios have been proposed explaining the emergence of life, both from environmental and chemical perspectives.
Sources and sinks of methane within an advanced serpentinization-influenced system were investigated at the Coast Range Ophiolite Microbial Observatory (CROMO) in Lower Lake, California. Subsurface water-rock reactions at CROMO contribute […]
Energetic particles continuously process water ice across astrophysical and planetary environments, from interstellar clouds and comets to icy planetary surfaces. Interpreting the resulting observables requires a physically grounded description of […]
JWST is transforming our ability to characterise small exoplanets, from sub-Neptunes to rocky worlds. A key open question is whether highly irradiated rocky planets can retain atmospheres or are stripped […]
The SPHEREx near-infrared space telescope is an all-sky spectroscopic survey mission launched on March 12th, 2025 UTC.
Earlier this week strong winds over the Saharan Desert blew westwards pushing clouds of dust and sand over southern and central Morocco and out into the Atlantic Ocean. This is […]
In addition to being delivered via exogenous means (e.g., chondritic meteorites and comets), amino acids are hypothesized to have been present on early Earth via Urey–Miller-type abiotic processes.
Building blocks of life such as amino acids, nucleobases, and fatty acids are central to prebiotic chemistry and represent key targets in the search for planetary biosignatures. In planetary materials, […]
China’s Tianwen-2 mission plans to return samples from a small, rapidly spinning Earth quasi-satellite (469219) Kamo’oalewa. Previous studies linked Kamo’oalewa to lunar composition and origin.
Planetary surface missions currently operate cautiously. On Mars, communication delays between Earth and rovers (typically between four and 22 minutes), as well as data transfer constraints due to uplink and […]
