The origin(s) of life (OoL), which has puzzled scientists for centuries, remains a major scientific challenge in the 21st century. Understanding the processes relevant to the OoL demands theoretical frameworks […]
The “NASA definition” enjoys broad popularity among scientists, particularly in the astrobiology community: life is “a self-sustained chemical system capable of Darwinian evolution.”
Would a definition of life be really helpful? Undoubtedly, scientists have to specify what they are trying to reproduce in the laboratory. The same applies when implementing a space mission […]
The question of “what is life?” has challenged scientists and philosophers for centuries, producing an array of definitions that reflect both the mystery of its emergence and the diversity of […]
Future telescopes will survey temperate, terrestrial exoplanets to estimate the frequency of habitable (ηHab) or inhabited (ηLife) planets.
Self-Nominations Invited for Task Force 1 (TF1): Development of NASA-DARES 2025: The 2025 NASA Decadal Astrobiology Research and Exploration Strategy
Space exploration has long captured the imagination of humanity, with technological innovation often taking centre stage. From advanced propulsion systems to intricate robotic explorers, our focus has been on the […]
It has been argued that the historical nature of evolution makes it a highly path-dependent process. Under this view, the outcome of evolutionary dynamics could have resulted in organisms with […]
RED is a Training School about the “Basics in Astrobiology”. Astrobiology addresses questions related to the origins of life, its evolution, and distribution in the Universe. This school aims to […]
Editor’s note: When we begin to study the variety iof life forms on other worlds we’ll need to have a way to catalog what we have discovered, make an image […]
