I have never thought too much about organics from space (or panspermia for that matter).pinball1970 said:I was quite surprised with his answer which 'not required' as far as his research is concerned.
Yes, organic molecules can survive the journey to Earth. Meteorites and comets, which often contain organic compounds, provide a protective environment that shields these molecules from the harsh conditions of space and atmospheric entry.
A variety of organic molecules have been detected in space, including amino acids, nucleobases, sugars, and hydrocarbons. These molecules have been identified in meteorites, comets, and interstellar dust clouds.
Scientists use isotopic analysis and molecular composition studies to determine the origin of organic molecules. Isotopic ratios that differ from those typically found on Earth can indicate an extraterrestrial origin. Additionally, the specific types and arrangements of atoms in these molecules can provide clues about their source.
While space-derived organic molecules can provide essential building blocks for life, the process of catalyzing the formation of life involves complex chemical reactions and environmental conditions. Research is ongoing to understand how these molecules could contribute to the emergence of self-sustaining chemical systems that could lead to life.
Experiments include simulating the conditions of early Earth in laboratory settings to observe how organic molecules interact and form more complex structures. Additionally, space missions like those conducted by NASA's OSIRIS-REx and ESA's Rosetta are analyzing samples from asteroids and comets to study their organic content and potential to contribute to prebiotic chemistry.
