Alien Atmospheres - Methane, CFCs and other signs of smart ETs
Moffet Field CA (NASA) Jul 29, 2014
Sometimes we get lucky: an exoplanet many light-years away passes in front of its star at the perfect angle. This transit allows us to read certain features of that planet's atmosphere. The resulting spectra - lines made by molecules like oxygen and methane - allow us a peek into that planet's chemical anatomy. Certain features of those atmospheres make it more likely that something, or someone, inside is breathing. In the last few months, we've found even better ways of looking for these signs of ... read more
