If aliens were blanketing their planets with powerful greenhouse gases, as we do, we might notice. This is evident from a recent thought experiment in which scientists identified five “artificial” greenhouse gases that, if abundant enough, could be found in the atmosphere of certain areas. exoplanets using existing technology, including the James Webb Space Telescope … Read more

This includes separating nitrogen and oxygen from the air for medical purposes, separating carbon dioxide from other gases in the carbon capture process or removing impurities from natural gas.

A new study from UC Riverside identifies the artificial greenhouse gases that would be giveaways to a terraformed planet. A … Read more
