The identification of terrestrial analogs is a key strategy for advancing our understanding of the geological and geochemical evolution of Mars.
Editor’s note: for more than half a century we have been learning how to use the viewpoint from space to study our home world. The instruments we have developed often […]
We report the first detection of stratospheric propadiene (CH2CCH2) and propene (C3H6) at Jupiter’s mid-to-high northern latitudes using IRTF-TEXES measurements recorded on March 5-6, 2025.
Titan, Saturn’s largest moon, possesses a dense N2–CH4 atmosphere driving complex organic chemistry. The interplay among photochemistry, aerosol formation, organic cloud condensation, and surface deposition makes Titan a natural laboratory […]
The modern Martian surface is cold, dry, oxidizing, and perpetually bombarded with radiation, rendering it generally inhospitable to life as we know it.
Microbial productivity, metabolite fluxes, nutrient cycling and biosignatures are directly linked to microbial growth rates, which remain largely unknown in subsurface environments.
We use a three-dimensional model to calculate steady-state climates at various intervals in Earth’s future, across a parameter space of increasing insolation and decreasing CO2 mixing ratio.
Every morning, clouds roll in, and by evening, they have cleared off. This sounds like a weather forecast for a coastal city here on Earth — but it’s for WASP-94A […]
Life thrives in Earth’s most inhospitable environments, from boiling hydrothermal vents to hypersaline lakes and frozen polar deserts, thanks to the remarkable adaptations of extremophilic microorganisms.
The vast chemical space of possible small molecules, estimated at 1060 compounds for molecules composed of just C, N, O, and S, is only sparsely occupied by biology.
