An international research team has identified the specific origins of most of the Martian meteorites that are now on Earth. They’ve traced the meteorites to five craters where they were […]
New research led by scientists at the Smithsonian proposes a plan to safeguard Earth’s imperiled biodiversity by cryogenically preserving biological material on the moon. The moon’s permanently shadowed craters are […]
Results of an experiment named “Test” on survival and variability of microorganisms in open space near the International Space Station are presented.

[NASA] ROSES-24 AMENDMENT 31: DELAY OF PROPOSAL DUE DATE FOR C.15 PLANETARY PROTECTION RESEARCH
Airborne microorganisms, especially those at high altitude, are exposed to hostile conditions, including ultraviolet (UV) radiation, desiccation, and low temperatures.
An SUV-sized Asteroid 2008TC# Impacted on October 7, 2008 in the Nubian Desert, Northern Sudan: Dr. Peter Jenniskens, NASA/SETI joined Muawia Shaddas of the University of Khartoum in leading an […]
The atmosphere hosts a microbiome that connects remote ecosystems but remains underexplored. In this study, we employed metagenomics to examine the ecological roles of the atmospheric microbiome, including the dispersal […]
Recent discoveries related to the habitability and astrobiological relevance of the outer Solar System have expanded our understanding of where and how life may have originated. As a result, the […]
![The age and configuration of the known planets in putative, icy exomoon-bearing Jupiter-like gas giant consisting of candidate exosystems. The size of the bubbles indicates the mass of the planets in MJup. The dotted, dashed, and solid black curves in the upper right corner of the plot show the estimated impact ratio in the case of Late Heavy Bombardment and are used as an indicator of higher probability bioaerosol ejection in space 28 (steady decrease impact flux: dotted and dashed lines, and single cataclysm - sensu stricto Late Heavy Bombardment: solid line scenarios) [51]. I.e. the curves may show the changing tendency in the probability of bioaerosol ejection and transportation in the case of various exosystems in the period marked by the transparent grey horizontal regions. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/06/Searching-For-Jupiter-And-Saturn.png?resize=1200%2C721&ssl=1)
Considering the possibility of complex organic molecules and microbial life appearing under the ice shell of those satellites in the Solar system, this study investigates the possible analog sources (targeting […]
Tardigrades can survive hostile environments such as desiccation by adopting a state of anhydrobiosis. Numerous tardigrade species have been described thus far, and recent genome and transcriptome analyses revealed that […]
