How microbial communities respond to extreme conditions in the stratosphere remains unclear.
Two fundamental questions have puzzled scientists for more than 150 years. “How did life become homochiral?” and “why was this specific handedness selected?”
A research team of Specially Appointed Associate Professor Harrison B. Smith of Earth-Life Science Institute (ELSI) at Institute of Science Tokyo and Specially Appointed Associate Professor Lana Sinapayen of National […]
The recent discovery of all five canonical nucleobases in samples from Bennu provides compelling evidence that some of life’s ingredients were synthesized abiotically in the parent body of this asteroid […]
Pushing back the detection limits, technological advances are now allowing the detection and analysis of very low content DNA samples. A so far unseen diversity of microbes emerges sometimes filling […]
On this date in 1971 the Astrobiology / Planetary Protection – themed film “Andromeda Strain” had begun playing in theaters.

About 15% of asteroids near Earth have small moons orbiting them, making binary asteroid systems common in our cosmic neighborhood.
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 search for both extant and extinct life within our Solar System and beyond has been a primary motivation for space exploration since its inception.
This paper provides experimental and numerical evidence supporting the occurrence of liposome congregation at the floors of meteor craters on Early Earth.
