As the only known habitable (and inhabited) planet in the universe, Earth informs our search for life elsewhere. Future telescopes like the Habitable Worlds Observatory (HWO) will soon look for […]
Resilience is a property of social, ecological, social-ecological and biophysical systems. It describes the capacity of a system to cope with, adapt to and innovate in response to a changing […]
The discovery of a biosphere on another planet would transform how we view ourselves, and our planet Earth, in relation to the rest of the cosmos.
The Mesoproterozoic eon, often regarded as mundane and static, lays the foundation for dramatic transformations in Earth’s physical and biological evolution during the subsequent Neoproterozoic.
Astrobiology, while traditionally focused on understanding the origin of life on Earth and the potential for life elsewhere, offers powerful tools and insights for addressing urgent challenges on our planet.
Current understanding suggests that as the Sun brightens in the far future, Earth’s carbonate-silicate cycle will offset increasing temperatures by drawing CO2 out of the atmosphere, ultimately leading to the […]
There is strong evidence that the atmospheric moisture content of several solar system planets, including Earth, has varied over their lifetimes.
Water and land surfaces on a planet interact with gases in the atmosphere and with radiation from the star. These interactions define the environments that prevail on the planet, some […]
Terraforming Mars toward sustainable life-supporting ecosystems poses unprecedented challenges. Extremophilic microbes, which thrive in Earth’s most extreme environments, offer promising biological strategies for initial Mars colonization providing tools for resource […]
A new paper outlines how scientists came together to put together the first microbial conservation roadmap under the leadership of Applied Microbiology International President, Professor Jack Gilbert.
