Nitrogen-bearing polycyclic aromatic hydrocarbons (N-PAHs) are key precursors to complex organic molecules in both the interstellar medium and the nitrogen-rich planetary atmospheres.
Over 3.5 years of exploration in Jezero Crater, the Perseverance rover has explored several geological units of diverse origins and natures, performing multi-technique remote analyses of the chemistry and mineralogy […]
Recent high-precision atmospheric observations with JWST is enabling detailed characterization of sub-Neptune atmospheres and motivating efforts to understand and constrain their interiors.
The agency’s six-wheeled geologist took a self-portrait during its survey of an ancient landscape that may predate the formation of Jezero Crater itself.
Electromagnetic (EM) sounding can constrain the electrical structure of Enceladus and, in turn, the salinity of its ocean and the porosity, fluid content, and thermal state of its hydrothermally active […]
Thermal fatigue has been observed to be an important driver of boulder evolution on asteroid Bennu through the development of morphological features such as exfoliation flakes and linear fractures in […]
Through photometry and spectroscopy, we studied the evolution of the activity and chemical composition of comet 67P during its 2025 and 2021 perihelion passages and of comet 103P during its […]
Magma ocean crystallisation sets up the early structure and long-term evolution of terrestrial planets. Recent seismic evidence signals the presence of a silicate layer at the base of Mars’ mantle.
Earth planning date: Friday, May 1, 2026 Chile’s Atacama desert is the driest mid-latitude desert in the world, receiving only 15 millimeters (0.59 inches) of precipitation per year. Only the […]
Earth’s earliest continents may have set the chemical stage for life by regulating boron levels in ancient oceans, a new study in Terra Nova suggests.
