This periodic table depicts the primary source on Earth for each element. In cases where two sources contribute fairly equally, both appear.

Key Building Block For Organic Molecules Discovered In Meteorites
Scientists from Japan and NASA have confirmed the presence in meteorites of a key organic molecule which may have been used to build other organic molecules, including some used by […]
The Astrobiological Periodic Table
The Astrobiological Periodic Table has been developed by astrobiologist Charles Cockell. This is the preliminary first version. A second, more advanced version is in development. Larger version.
Amino Acids in Chondrites
Many theories about the origins of life involve the delivery of organic molecules to the early Earth by objects from space. Previously, scientists have identified amino acids in carbon-rich meteorites. […]
The Origin of Complex Organic Molecules in Prestellar Cores
Complex organic molecules (COMs) have been detected in a variety of environments, including cold prestellar cores. Given the low temperature of these objects, these last detections challenge existing models. We […]
Key to Cosmic Carbon's Molecular Evolution
Scientists at NASA’s Ames Research Center now have the capability to systematically investigate the molecular evolution of cosmic carbon. For the first time, these scientists are able to automatically interpret […]
NASA Research Shows DNA Building Blocks Can Be Made in Space
NASA-funded researchers have found more evidence meteorites can carry DNA components created in space.
Carnegie: Meteorites – Tool Kits for Creating Life on Earth
Meteorites hold a record of the chemicals that existed in the early solar system and that may have been a crucial source of the organic compounds that gave rise to […]
NASA Identifies Carbon-rich Molecules in Meteors as the “Origin of Life”
Tons, perhaps tens of tons, of carbon molecules in dust particles and meteorites fall on Earth daily. Meteorites are especially valuable to astronomers because they provide relatively big chunks of […]
Particles, Environments And Possible Ecologies In The Jovian Atmosphere
The eddy diffusion coefficient is estimated as a function of altitude, separately for the Jovian troposphere and mesosphere. Complex organic molecules produced by the Ly alpha photolysis of methane may […]
