Seven Tanpopo exposure units with different samples are placed inside the exposure panel. The Tanpopo-5 investigation studies the origin, transportation, and survival of life in space.
Panspermia is the hypothesis that life originated on Earth from the bombardment of foreign interstellar ejecta harboring polyextremophile microorganisms.
Editor’s note: Upon entering a spacecraft or arriving on a new, inhabited world, you would probably like to have your tricorder to have the ability to do a quick assay […]
There are life forms in space and the ancestor of Earth life came from interstellar space according to models like panspermia.
Reduced-oxidation-state phosphorus (reduced P, hereafter) compounds were likely available on the early Earth via meteorites or through various geologic processes.
Halite (NaCl mineral) has exhibited the potential to preserve microorganisms for millions of years on Earth. This mineral was also identified on Mars and in meteorites.
How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers from the University of […]
In this work we consider the potential of cometary impacts to deliver complex organic molecules and the prebiotic building blocks required for life to rocky exoplanets. Numerical experiments have demonstrated […]
Tons of space particles enter the Earth atmosphere every year, being detected when they produce fireballs, meteor showers, or when they impact the Earth surface.
A research team led by a Yale astronomer has some advice for our next close encounter with a wandering, interstellar object. Check its X-rays on the way out. Since 2017, […]
