Life Forms Can Planet Hop On Asteroid Debris – And Survive
Tiny life forms tucked into debris from an asteroid hit could catapult to other planets – including Earth – and survive, a new Johns Hopkins University study finds.
The COSPAR Policy On Planetary Protection: An Overview Of Governance And Activities
The search for both extant and extinct life within our Solar System and beyond has been a primary motivation for space exploration since its inception.
Experimental And Numerical Modeling Of Liposome Congregation In Meteorite Craters Of Early Earth
This paper provides experimental and numerical evidence supporting the occurrence of liposome congregation at the floors of meteor craters on Early Earth.
Survival Limits Of Psychrotolerant Microorganisms With Relevance For Planetary Protection Of The Icy Moons
Investigating the survival limits of extremophilic microorganisms exposed to simulated space conditions can shed light on the ability of terrestrial microorganisms to survive and propagate on other planetary bodies.
Can The Timing Of The Origin Of Life Be Inferred From Trends In The Growth Of Organismal Complexity?
The origin of life embodies two fundamental questions: how and when did life begin? It is commonly conjectured that life began on Earth around 4 billion years ago.
High-Pressure Torsion-Induced Transformation of Adenosine Monophosphate: Insights into Prebiotic Chemistry of RNA by Astronomical Impacts
The origin of life is yet a compelling scientific mystery that has sometimes been attributed to high-pressure impacts by small solar system bodies such as comets, meteoroids, asteroids, and transitional […]
Earth’s Ancient Atmosphere May Have Rained Down The Key Ingredients For Life
New research published in Proceedings of the National Academy of Sciences reveals that Earth’s ancient atmosphere may have acted as a global chemical factory, naturally producing sulfur-containing molecules that would […]
Potential Metabolic Viability On Asteroid Chemistry
While it has been long supposed that asteroids played a role in the delivery of important prebiotic compounds to early Earth, the exact nature of the interactions between asteroidal material […]
Lunar Spacecraft Exhaust Could Obscure Clues To Origins Of Life
Over half of the exhaust methane from lunar spacecraft could end up contaminating areas ofthe moon that might otherwise yield clues about the origins of earthly life, according toa recent […]
