The oxygenation of Earth’s atmosphere 2.3 billion years ago, which on exoplanets is expected to be most detectable via the UV ozone feature at ∼0.25 μm, is often regarded as […]
Enceladus offers our best opportunity for exploring the chemistry of an ocean on another world.
We present a comprehensive multivariate statistical analysis of 517 exoplanets from the NASA Exoplanet Archive to identify potentially habitable worlds and quantify detection bias in current surveys.
Glaciers are important regulators of the Earth’s climate system, affecting the hydrological cycle, energy balance and the development of downstream ecosystems. Other than the polar regions, the Tibetan Plateau stands […]
The search for life beyond Earth currently hinges on the detection of biosignatures that are indicative of current or past life, with terrestrial life being the sole known example.
Studying the survival of terrestrial microorganisms under Martian conditions, particularly in the presence of perchlorates, provides crucial insights for astrobiology.
Planetary caves are desirable environments for the search for biosignatures corresponding to extant or extinct extraterrestrial life due to the protection they offer from surface-level solar radiation and ionizing particles.
NASA’s return to the Moon coincides with explosive growth in exoplanet discovery. Missions are being formulated to search for habitable planets orbiting other stars, making this the ideal time to […]
Europa, a moon of Jupiter, is a high-priority target for space exploration because of its potential to harbor life. A landed mission concept to collect and analyze samples for signs […]
We study the evolution of the Vis-NIR reflectance spectrum of salty granular ice analog samples in a simulation chamber under conditions relevant to the surface of Europa.
