"The Planetary Habitability Laboratory (PHL) is a research and education virtual laboratory dedicated to studies of the habitability of Earth, the Solar System, and exoplanets. Check the projects link for more details about the scientific projects. There are also links to scientific and educational materials, data and software tools related to planetary science and astrobiology that might be of interest to scientists, students, and the general public. The PHL is managed by the University of Puerto Rico at Arecibo."

'Project EDEN exploits state-of-the-art knowledge and methods in astrophysics, planetary sciences, and astrobiology to search for and characterize the closest habitable worlds.'

The Sustainability Solution states: the absence of ETI observation can be explained by the possibility that exponential or other faster-growth is not a sustainable development pattern for intelligent civilizations.

Of the twenty amino acids used in proteins, ten were formed in Miller's atmospheric discharge experiments. The two other major proposed sources of prebiotic amino acid synthesis include formation in hydrothermal vents and delivery to Earth via meteorites. We combine observational and experimental data of amino acid frequencies formed by these diverse mechanisms and show that, regardless of the source, these ten early amino acids can be ranked in order of decreasing abundance in prebiotic contexts. This order can be predicted by thermodynamics. The relative abundances of the early amino acids were most likely reflected in the composition of the first proteins at the time the genetic code originated. The remaining amino acids were incorporated into proteins after pathways for their biochemical synthesis evolved. This is consistent with theories of the evolution of the genetic code by stepwise addition of new amino acids. These are hints that key aspects of early biochemistry may be universal.
