Because oxygen-bearing sulfate minerals trap and preserve signals from Earth’s atmosphere, scientists closely study how they form. Sulfates are stable over billions of years, so their oxygen isotopes are seen […]
Frozen in time, ancient microbes or their remains could be found in Martian ice deposits during future missions to the Red Planet.
M dwarfs have long been prime targets in the search for habitable exoplanets, owing to their abundance in the galaxy and the relative ease of detecting Earth-sized worlds within their […]
![[L] Latitude-longitude maps of surface temperature overlaid with the wind field at the bottom layer, and surface precipitation. The black contours indicate where the surface temperature is 50◦ Celsius. [R] Latitude-longitude maps of surface temperature overlaid with the wind field at the bottom layer, and surface precipitation, for ISR = 1580 Wm−2 , which brings the climate to the onset of a runaway greenhouse effect. The minimum surface temperature between the two surface albedo cases is 345 K or 72◦C.Latitude-longitude maps of surface temperature overlaid with the wind field at the bottom layer, and surface precipitation, for ISR = 1580 Wm−2 , which brings the climate to the onset of a runaway greenhouse effect.

Teegarden’s Star b, a nearby terrestrial world receiving an Earth-like instellation, is a prime candidate for next-generation observatories targeting temperate exoplanets in their habitable zones.
Any life on Mars in the past, present, or future would have to contend with challenging conditions including, among others, shock waves from meteorite impacts and soil perchlorates—highly oxidizing salts […]
Jezero Crater on Mars is a critical site for investigating ancient aqueous environments due to its preserved delta and lacustrine features.
Modern and ancient hypersaline lakes and oceans have been identified across the solar system, but the habitability and potential of these environments to preserve organic matter remain unknown.
Microbes from terrestrial extreme environments enable testing of biosignature production in conditions relevant to astrobiological targets.
NASA astronaut Jasmin Moghbeli took pictures of MBRSC astronaut Mohammad AlMulla while he was conducting a microbiological investigation close to the underground base camp in Abel Cave.
Ettore Lopo and Marco Vattano, the science team of ESA CAVES 2025 course, explain the latest details of microbiological analyses to astronauts Mohammad AlMulla (MBRSC) and Makoto Suwa (JAXA).
