Well-known exoplanet researcher Dr Michel Mayor ( discoverer of Peg 51b with Dr Didier Queloz in 1995 ) today announced the discovery of the lightest exoplanet found so far. The planet, “e”, in the famous system Gliese 581, is only about twice the mass of our Earth. The team also refined the orbit of the planet Gliese 581 d, first discovered in 2007, placing it well within the habitable zone, where liquid water oceans could exist:

As an overall strategy, JWST is more of an intermediate and supplanting step:
On the European side, PLATO is supposed to launch around the same time that E-ELT becomes active (and around the same time GAIA's catalogue gets published), which will probably make a great pair in space-based detection and first characterization and then ground followup observation throughout the second half of the 2020s. The US side similarly works with TMT and the still only proposed WFIRST and ATLAST missions in the same timeframe. |
