Original Caption

Limiting sensitivity of techniques of planet finding. Shown in the above figure are the sensitivity limits of radial velocity surveys, astrometric surveys, microlensing surveys, and space-based transit techniques. The lines show 5-σ limits with 50 re-samples. The shaded areas show the expected progress towards the detection of Earth-like planets by 2006 and 2010. Planets in our Solar System are also indicated, as well as the highlighted target area of TPF science. The filled circles indicate the planets found by radial velocity surveys (blue), transit surveys (red), and microlensing surveys (yellow). The discovered extrasolar planets shown in this plot represent the reported findings up until 31 August 2004.
