This plot shows the extension of the recently redefined Habitable Zone around F, G, K, and M stars. The Warm 'Habitable' Zone is divided into a narrower 'Conservative Habitable Zone' (light green) and a wider 'Optimistic Habitable Zone' (dark green). Earth is at the inner edge of the 'Conservative Habitable Zone.' CREDIT: PHL @ UPR Arecibo.
