Researchers have quantified a pathway for the formation of molecular oxygen from the interaction of carbon dioxide with electrons, key information for searches of life on other worlds.
Using data from the spaceborne JWST, researchers can infer the contents of exoplanet atmospheres with potential implications for the habitability of these worlds.
The present day habitability of Mars is an area of research that has exploded hugely in the last decade, to the extent that it s often hard to keep track of everything that s going on. This is by way of background material for my other articles on habitability of Mars.
