Team wonders about CFCs in exoplanet atmospheres.
While the above headline is flippant, the research attempts are not.
A team of scientists across the nation is working on observing planets orbiting other stars, looking for signs of greenhouse gas emissions.
Doctor Jacob Haqq-Misra tells KTOK, chlorofluorocarbons, once widely used as a refrigerant and aerosol propellant, linger in a planet's atmosphere.
"If we saw an awful lot of CFCs, that as far as we know doesn't correspond to any non-technological process."
He said in other words, CFCs aren't expected to occur naturally.
Haqq-Misra said the presence of greenhouse gases like CFCs could indicate an advanced civilization. An indication of an industrialized world.
Haqq-Misra and others at the Blue Marble Science Institute of Space are looking at developing computer models of exoplanet atmospheres.
