Life on Earth has been shaped by transformative microbial innovations and singularities that redefined planetary systems, from oxygenic photosynthesis to biological nitrogen fixation.
Our paper fills this gap based on a three year-long study by the NExSS Quantitative Habitability Science Working Group. We reviewed past studies of habitability, but find that the lack […]
In the State of the Cryosphere 2024 – Lost Ice, Global Damage report, over 50 leading cryosphere scientists warn of vastly higher impacts and costs to the global economy given […]
Around the equator, for example, vast networks of channels spread from Martian highlands, branching like trees and emptying into lakes and even, possibly, an ocean. NASA’s Perseverance rover, which landed […]
A fundamental goal of astrobiology is to detect life outside of Earth. This proves to be an exceptional challenge outside of our solar system, where strong assumptions must be made […]
Cosmic rays (CR), both solar and Galactic, have an ionising effect on the Earth’s atmosphere and are thought to be important for prebiotic molecule production. In particular, the H2-dominated atmosphere […]
Warming Mars’ surface could be a step toward making it suitable for life, but would represent a major science and engineering challenge.
For the first time, researchers have demonstrated that certain lichen species can survive Mars-like conditions, including exposure to ionising radiation, while maintaining a metabolically active state.
The colonization of Mars presents extraordinary challenges, including radiation exposure, low atmospheric pressure, and toxic regolith.
Scientists find evidence that our oceans used to be green, suggesting that this may be a sign of primitive life, including that on alien worlds.
