Habitable Zones & Global Climate: January 2016

Why did the emergence of our species require a timescale similar to the entire habitable period of our planet?

The ubiquity of M dwarfs, combined with the relative ease of detecting terrestrial-mass planets around them, has made them prime targets for finding and characterising planets in the "Habitable Zone" (HZ).

"A globular cluster might be the first place in which intelligent life is identified in our galaxy," says lead author Rosanne Di Stefano of the Harvard-Smithsonian Center for Astrophysics (CfA).
