NASA team looks to ancient earth first to study hazy exoplanets
Moffett Field CA (SPX) Feb 10, 2017
For astronomers trying to understand which distant planets might have habitable conditions, the role of atmospheric haze has been hazy. To help sort it out, a team of researchers has been looking to Earth - specifically Earth during the Archean era, an epic 1-1/2-billion-year period early in our planet's history. Earth's atmosphere seems to have been quite different then, probably with little available oxygen but high levels of methane, ammonia and other organic chemicals. Geological evidence sugg ... read more
