The ongoing exploration of planets such as Mars is producing a wealth of data to define habitable environments beyond the Earth.
Extremophilic bacteria from extreme environments, such as the Atacama Desert, Salar de Huasco, and Antarctica, exhibit adaptations to intense UV radiation. In this study, we investigated the genomic and structural […]
Earth’s earliest life forms developed ways to survive the harmful effects of arsenic to cope with dramatic changes in their environment, a new study suggests.
Editor’s note: If we aspire to mount expeditions to new worlds and then embrace the task of characterizing and quantifying whatever life forms we find, the ability to map and […]
Previous models of microbial survival on the moon do not directly consider the permanently shadowed regions (PSRs). These regions shield their interiors from many of the biocidal factors encountered in […]
The subsurface oceans of icy moons, expected to retain appreciable concentrations of ammonia, are of significant interest to astrobiology. On Earth, ammonia is released in large quantities, primarily through anthropogenic […]
Executive Summary: Distinct lines of scientific inquiry drives the separation of NASA’s fundamental life science research into Space Biology and Astrobiology.
The relative abundances of exotic environments provides us with (uninformed) bounds on the habitability of those environments relative to our own, on the basis that our presence here is not […]
Research on the morphology, physiology and genomics of Asgard archaea has provided valuable insights into the evolutionary history of eukaryotes.
The experiment “Phage and Uracil Response” (PUR) will be accommodated in the EXPOSE facility of the International Space Station (ISS). Its objective is to examine and quantify the effect of […]
